Why Do People Still Use Copper SFP Transceivers?


Electric sfp Introduction

In the age of fiber optics and lightning-fast data transfer, it might come as a surprise that copper SFP (Small Form-factor Pluggable) transceivers are still widely used. In this blog post, we will discuss why copper SFPs continue to hold their ground in the networking world, as well as their advantages and disadvantages compared to their optical counterparts. We will also help you understand how to choose the right copper SFP for your needs.

What is Copper SFP?

Copper SFPs are transceiver modules that support data transmission over copper cables, such as Cat5e or Cat6, using RJ45 connectors. They are commonly used in applications where short distances and lower costs are priorities, like data centers and local area networks (LANs). Two popular copper SFP options are SFP-10G-T (10 Gigabit Ethernet) and 1000BASE-T (1 Gigabit Ethernet), while other notable variants include SFP-10G-T-S, SFP-1G-T, and QSFPTEK transceivers.

How Does the RJ45 SFP Transceiver Work?

An RJ45 SFP transceiver is a hot-swappable module that plugs into the SFP port of a network device, such as a switch or router. The transceiver receives electrical signals from the device and converts them into a format suitable for transmission over copper cables. On the receiving end, another transceiver converts the signals back into electrical form, allowing the data to be interpreted by the receiving device.

These transceivers support various data rates and standards, such as 1000BASE-T (1 Gigabit Ethernet) and 10GBASE-T (10 Gigabit Ethernet), and are compatible with a wide range of network devices. The use of copper cables with RJ45 connectors makes copper SFPs an attractive choice for short-range applications, as they are cost-effective and easy to install.

What is the Difference Between Optic SFP and Copper SFP?

Optical SFPs and copper SFPs both serve the same purpose: to facilitate data transmission between network devices. However, they differ in their underlying technology and the types of cables they use. Here are the main differences between the two:

  1. Transmission Medium: Optical SFPs use fiber optic cables for data transmission, while copper SFPs use copper cables.
  2. Distance: Optical SFPs can transmit data over much longer distances than copper SFPs, often spanning several kilometers, while copper SFPs are limited to shorter distances, typically around 100 meters.
  3. Data Rate: Both types of SFPs support a range of data rates, but optical SFPs generally offer higher speeds than copper SFPs.
  4. Cost: Copper SFPs and their associated cabling are typically less expensive than optical SFPs and fiber optic cables, making them more attractive for short-range applications.
  5. Signal Interference: Copper cables are more susceptible to electromagnetic interference (EMI) and signal degradation compared to fiber optic cables, which can lead to reduced performance over longer distances.

How to Choose Copper SFP and SFP+?

When choosing a copper SFP or SFP+ transceiver, consider the following factors:

  1. Compatibility: Ensure that the transceiver is compatible with your network devices and supports the desired data rate and Ethernet standard.
  2. Distance: Determine the maximum distance between your network devices and choose a copper SFP with a range that meets your requirements. Remember that copper SFPs are best suited for short-range applications.
  3. Data Rate: Select a copper SFP that supports the required data rate,such as 1 Gigabit Ethernet (1000BASE-T) or 10 Gigabit Ethernet (SFP-10G-T).
  1. Cable Type: Choose a copper SFP that is compatible with the type of copper cable you will be using, such as Cat5e or Cat6.
  2. Vendor: Opt for a reputable vendor, like QSFPTEK, that offers high-quality transceivers and provides good customer support.
  3. Budget: Copper SFPs are generally more cost-effective than optical SFPs, but prices can still vary. Consider your budget when selecting a copper SFP, but don’t compromise on quality for the sake of saving a few dollars.
  4. Power Consumption: Copper SFPs typically consume more power than optical SFPs, so factor in power consumption when making your choice.


Copper SFP transceivers continue to be popular due to their cost-effectiveness, ease of installation, and compatibility with a wide range of network devices. When choosing a copper SFP or SFP+, be sure to consider compatibility, distance, data rate, cable type, vendor, budget, and power consumption. By carefully weighing these factors and selecting the right copper SFP for your needs, you can build a reliable and cost-effective network solution that meets your requirements.

6 Sfp Transceiver Facts You Should Know

 When you hear the name SFP transceiver, you might think that you know everything about it. Only experienced professionals know everything there is to know about these often-overlooked devices. The sfp optical module, or miniGBIC, has many iterations. Each version has traits that make it unique. Let’s now break down the SFP optical transceiver.

1. Sfp transceiver: What Is It?

The small form-factor pluggable (SFP) transceiver is a small device that converts computer data from one form to another for transmission. The 1g SFP transceiver is attached to devices such as network switches, network interface cards (NICs), and routers. The tail end of an sfp optical module joins a copper or optical fiber cable. The SFP transceiver is hot-pluggable thanks to the design of gigabit sfp ports.


Types of sfp transceivers include SFP, QSFP, SFP+, and QSFP+.Due to the different standards met by SFP connectors, you can make a robust network with them. An SFP transceiver, being hot-pluggable, can be upgraded quickly and on the fly. SFP modules support single-mode or multi-mode cables, and they can transmit data up to 80 kilometers. Furthermore, the sfp optical transceiver has bandwidths ranging from 10 megabits per second to 40 gigabits per second.

2. SFP module Differences

The market has a plethora of SFP modules, making it hard to select the best one. If you want to choose the ideal sfp transceiver, you must first define your objectives. The best sfp optical transceiver for one person might be of little to no use for another person. Regardless of the person looking to buy an sfp transceiver, the choice becomes simpler by looking at the specifications they need.

Sfp Transceiver Transmission Distance

The first class of SFP modules, according to distance, is short-range (sr) SFP modules. The other class is long-range sfp. Short-range sfp modules use multi-mode fiber cables to transmit data. A normal short-range SFP sends data up to 500 meters, while an extended SFP supports a 2-kilometer distance.

A long-range SFP transceiver can be standard or extended. It sends data between 10 and 80 kilometers over a single-mode fiber cable.

Sfp Transceiver Bandwidth

Your preferred sfp transceiver should be faster than your required speed. The data transfer limit of SFP modules ranges between 10 megabits per second and a gigabit per second. The SFP+ transceiver has a bandwidth of 10 Gbps. Additionally, QSFP+ can reach up to 40 Gbps. If you provide more headroom on your network, you don’t have to upgrade it for years.

sfp data rate capabilities

The SFP Transceiver cable type

An SFP transceiver can use copper or fiber optic cables. How you have arranged your servers will determine the type of cables you require. If your racks are a short distance apart, you can choose copper cables. However, if the racks are more than 15 meters apart, your only choice is optical cables. Optical cables are cheaper than copper cables which makes them the only option for long-distance connections.

If your racks have many wires, you should use copper cables because they are easier to bend without damage.

Copper cables are not preferable for networks where data loss is unacceptable. An SFP transceiver with copper cables can be inefficient if there is electromagnetic interference. Optical cables, however, are not affected by electromagnetic interference. They are therefore suitable for mission-critical data networks.

3. SFP fiber optics and Direct Attach Cable

A Direct Attach Cable (DAC) is a Twinaxial cable that has transceivers attached on both ends. You cannot detach the SFP transceiver at the end of this type of cable. Transmitting data over short distances in a server room requires the use of DACs. The main benefit of a DAC cable is that you do not need to use separate transceivers and cables. You need less money to buy DACs, and it also costs less to maintain them.

A DAC supports plug-and-play just like the SFP transceiver. The DAC also consumes less energy compared to standalone optical modules.

4. The Question Of Compatibility

Before you buy an SFP transceiver, you should find out if it works with your devices. The problem with compatibility is that not all sfp manufacturers make switches and other host devices. How do you make sure that an SFP optical module will work with your host devices? The only way to be safe is to buy compatible modules from manufacturers like QSFPTEK.

Many people find that the Cisco sfp price exceeds their available budget. These people turn to third-party sfp manufacturers to buy optical modules. It is an excellent decision because third-party manufacturers such as QSFPTEK supply compatible SFP transceiver modules. These modules work with multiple host devices regardless of the OEM.

5. Standards Supported By An SFP optical module

Optical transceivers support multiple standards. The Multi-Source Agreement, commonly known as MSA, is the most common for third-party optical modules. The standard ensures that an SFP transceiver supports host devices of many different OEMs. Devices that conform to the MSA standard work with devices from other sfp manufacturers bearing the same certification.

Standards such as the MSA ensure cross-compatibility of optical modules. They also make it easier for manufacturers to develop products quickly. It is because the MSA specifies many electrical and mechanical parameters, so companies can know what works. That saves a lot of time and money in R&d.

Fiber optic Transceiver

What is a Fiber Optic Transceiver

Fiber optic Transceiver is used as a subcomponent of SFP Transceivers which are network equipment that is used as interface modules between network components and cabling. SFP stands for small form-factor pluggable, while the word transceiver is the portmanteau of transmitter and receiver, meaning the unit contains both of those components in itself. So, we can say Fiberoptic Transceivers both send and receive data using a fiberoptic medium. Generally speaking, Fiberoptic Transceivers are designed in accordance with Multisource Agreement in order to ensure compatibility between vendors

How does a Fiber Optic Transceiver Work?

As we discussed before, Fiberoptic transceivers use to send and receive data from a fiberoptic medium. The data may be sent in different protocols. To send certain data, the SFP Fiber Module would first encode it in the form of light pulses. Then data will be sent using a light source. Encoded data would travel in the form of light bouncing from the walls of the fiberoptic cable all the way from one end to another. To receive data, the SFP Fiber Module would be using a photodiode semiconductor. The photodiode would receive the signals, which would be decoded back to the original data by the module. In a typical SFP Fiberoptics module there would be two cables, one dedicated to sending the data and the other dedicated to receiving it. There are a few varieties that utilize a single cable, however since a single cable cannot do transmission and reception at the same time, modules using only a single cable can only be doing one of those in a given time.

Why Fiber Optic Transceiver is a Great Deal?

When we consider the world we live in, we can see the exponentially increasing network needs every day. With this continuously growing demand, a fast network connection is now a must have for everybody from individual users to large companies.

When we take the traditional copper wire-based network infrastructure into our hands, we can see that while it functioned very well in the past, it is no longer adequate for the growing needs. Even though conduction in copper wire is respectively fast, when we look at the size of the data transferred through networks every single day, it falls short. Now, let’s take a look into fiber optic cables. As we talked before SFP Fiber Modules use light to send and receive data. So, while it wouldn’t be entirely true to say our data travel in light speed in fiberoptic cables, it would give us a good idea to emphasize how fast fiberoptic cables transfer data. To give numbers, data travels in the fiberoptic cables in approximately 0.7 times of the light speed. So, using fiberoptics can give the user a much better data rate than copper.

Furthermore, speed isn’t the only factor that makes fiberoptics important. Copper cables are ferromagnetic, whereas fiber patch cables are not. Light can keep a strong signal between two points whereas copper would be affected by the electromagnetic signals in its path, copper wires close to each other may even interfere with each other. Due to electromagnetic interference, signals in copper wire may weaken drastically. However, fiberoptic cables are not prone to electromagnetic interference, hence can be placed into a much more compact space and cover greater distances much more effectively. When all of this is taken into account it is not much difficult to see why Fiberoptic Transceivers are crucial to our networking needs.

What is the Role of SFP Fiber optics?

As we mentioned before SFP transceivers are the interface modules between network components and cabling. In order to transmit data in Fiberoptic cables, fiberoptic infrastructure solely is not enough, the network equipment user has, should also consist of the module that will convert the data to the wanted structure, i.e., the light. SFP Fiberoptics Module simply does this upgrade, and it allows us to use fiberoptic infrastructure networks in a very easy way! As emphasized in the name, SFP Fiberoptics modules are compact in size and they are hot pluggable, means that you can upgrade your network without making major changes in the infrastructure.

Using an SFP Fiberoptics module, not only the user would upgrade the maximum data rate of the network, but due to their physical nature SFP Fiberoptics modules cover much higher distances when compared to copper using modules, meaning their range is much higher. There is a great variety of modules available in the market which support high data rates, cover large distances, contain the channel count best fitting for the user.

SFP optics devices and Fiberoptic Transceivers are what allow us to take use of this high technology while sending and receiving data. As we go into the future, with the IoT devices, and big data implementations, the networking needs are only expected to grow. Hence, we believe we can easily say Fiberoptic Transceivers and SFP Fiber Modules will only be more crucial in the future.

To Summarize…

In the continuously growing world we live in, fiberoptics can be considered as the new standards right now. The best way to follow with these growing standards is the get the best use of SFP Fiberoptics Modules. Due to their physical nature, using them provides the user the network upgrade very easily. Hopefully with this blog article we managed to give you an idea of the importance of fiberoptics transceiver and SFP Fiberoptics Modules. Plus, here is a big tip for anyone who is on board with a network upgrade: With the big variety of products available on QSFPTEK website, it is incredibly easy find the best product for the user. With the selection of SFP modules of QSFPTEK, it is inevitable to meet and exceed the highest networking standards of today.

Are Modern Third-Party SFP 10g lr Transceivers As Good As Their OEM Counterparts?

One common question facing network engineers today is whether they should buy generic sfp 10g lr optic transceivers instead of OEM transceivers. In the past, the answer to whether you could trust an sfp 10g sr transceiver from a third party was a shifting goalpost. The quality of third-party optic modules from QFSPTEK has always been consistently good. It is now common for fiber optic transceivers to have comparable performance with OEM brands even though the sfp 10g sr price of generic brands is significantly lower. By the end of this article, we shall break down why generic transceivers are worth a second look.

Why Do OEMs Claim To Have Better SFP 10g lr Modules?

sfp 10g lr
sfp 10g lr

The sfp+ transceiver market has changed dramatically because of rapid technological advancement. It is now easier than ever for a third party to make an sfp+ module that can trade blows with any OEM branded unit. The OEMs were not counting on having to deal with so much competition so quickly. As a knee-jerk reaction, they have resulted in spreading fear and misinformation to prevent people from buying the sfp 10g lrm module not made by them.

There are several key points that they say differentiate them from third parties that make the 10g sfp+ port. Let’s delve deeper into the perceived differences between an OEM sfp 10 lr module from a third-party version.

Compatibility of Third-party SFP 10g sr Transceiver With OEM Switches

The age-old excuse used by OEMs to dissuade people from buying third-party optic modules is that they might not work properly. This point used to be true some time ago before third parties started to make compatible transceivers. When ordering a 10g sfp+ Port from a third party, a person can get a version compatible with numerous OEM switches. Some third parties will even offer to write code to an sfp+ module to make it compatible with the customer’s switch.

To try to counter this, OEMs now commonly include software in their switches that check if an attached transceiver is from a third party to disable some or all its features. Some also claim that third-party sfp+ transceiver modules invalidate their switch warranty.

Is An OEM SFP 10g sr Module Better Quality Than Generic Ones?

The quality of a 10gbase sr sfp module varies a lot from one third-party manufacturer to another. Some manufacturers don’t employ stringent control over their production process to make reliable sfp 10g sr s modules. These ‘bad apples’ taint the image of other makers of generic sfp 10g sr s modules.

The picture on the ground is quite different from the one OEMs paint about third-party optical sfp 10g lr module reliability. What OEMs don’t tell you is that their devices share many components with third-party units. The reason is that OEMs often don’t manufacture the chips inside their modules. They simply source them from manufacturers like Finistar, package them, and brand them. Sure, they may have patents on their designs, but the components they use are owned by other companies and are hence available to both OEM and third-party alike.

The Performance Debate About sfp 10g lrm Modules

Any customer who wants to buy an sfp 10g lr module wants to know if it will be as fast as a unit from an OEM brand. OEMs want you to think that generic units won’t perform as well as theirs but this is far from the truth. The fact is that to get industry standardization marks, manufacturers of generic sfp 10g modules must meet a set of rules set out by various governing bodies. This means that performance must meet a certain threshold, which it often surpasses for major third-party manufacturers such as QFSPTEK.

Is a Third Party sfp 10g sr Transceiver Different From An OEM Version?

The gap between an OEM sfp+ port and a generic one has been reducing in leaps and bounds. Sure, there is a certain amount of confidence that people get when the name on their sfp+ connector matches the name of the switch it is attached to. Original equipment manufacturers want people to believe that that is the only configuration that will give them the best performance and reliability. However, people who buy sfp 10g sr replacement from third parties quickly find out that the case for OEM modules is not as strong as they would have you believe.


Benefits Of Buying Generic SFP 10g sr Transceivers

The following advantages of generic optic modules make them a no-brainer for anybody looking for great network equipment no matter where it comes from. They are the reasons why OEMs do not want people to buy cisco sfp 10g sr modules from third parties.

How sfp 10g sr Price Compares With OEM units

Original equipment manufacturers have big R&D departments which means that they spend a lot to develop their products. The 10g sfp price is significantly higher for an OEM product compared to a generic one. The demand for low-cost transceivers such as the 10g sr module is on the rise and this gives third party manufacturers a positive outlook according to QSFPTEK News.

You Get Better Service From A Generic sfp+ module Manufacturer

Contrary to what many people believe, it is common for third-party module manufacturers to have a wider product portfolio than OEMs. Third parties can also provide longer warranty periods for their sfp+ transceiver units because of the need to compete favorably with other generic brands and OEMs.

Wider Compatibility Of Generic Optic Transceivers

It is a fact that no optic transceiver works better with a particular switch than one from the manufacturer of that switch. This strength of OEM modules is also one of their greatest weaknesses and one shared by a few generic cisco sfp 10g sr compatible transceivers. Generic transceivers are made to work with a broad range of switches and other equipment.


The quality and reliability of third-party transceivers have improved dramatically. The question of whether you should buy an OEM SFP 10g sr has now been put to rest. You can now expect comparable performance from generic transceivers to most OEM-branded ones.

All the things you should know about SFP Transceiver


SFP optical module is a short term for small form-factor pluggable, it is a small compact, a pluggable device that helps with the connection of and its interfaces between cable and networking equipment. It helps in customizing the user’s networking equipment since these are available with a specification to help the users meet their specific needs.

Why does SFP is also known as miniGBIC? The GBIC is the term for Gigabit Interface Converter, it was called miniGBIC, because GBIC is larger than SFP, so it was called miniGBIC. However, since GBIC is quite larger and bigger and still works with the same purpose, it was replaced by SFP in most applications today.

Remember that gigabit ethernet sfp comes with a lucent connector while GBIC comes with the standard connector, both of them are fiber-optic but they are differentiated based on their sizes.

According to the market, there are lots of SFP transceivers and SFP cables, so you should know what is best for you. You can choose if between single-mode or multi-mode, depending on the type that you need since, it helps in transmitting the data anywhere in the world. It provides a transfer rate of 500m as far as 70km to 80km, with a speed of 10 Mbps up to 40 Gbs. As you can see that’s efficient for the users who want to have a faster speed of connections.

The first thing that the users need to see is how far the distance is, considering it will make them choose if they need a Short Reach sfp fiber optics or the Long Reach sfp fiber optics.  If you want a cheaper option, you can probably choose SFP for shorter a distance. Always put in mind that before the users purchase the products, they should know what material do they need and be compatible with the equipment.

How do Single-Mode fiber optic cable and Multi-Mode fiber cable differ? They both have a core but differ in size and wavelength. Not just that, when it comes to fiber optic patches don’t, they have similar color, Single-mode cable has a yellow cord while the Multi-mode cable has an aqua green cord.

What are the things to consider in checking with SMF and MMF SFPs? First, ensure that both ends of the fiber patch cord have the same wavelength, with consistent color modules. Upon choosing the SFP module, make sure that you confirm the transmission distance and wavelength. Always remember that bending the fiber optic will result to increase attenuation. Lastly, keep on track with the prices check and verify correct cost as the cost for it keep increasing over overtime.

The achievable network speed today is 10G speed with the help of an SFP optic. Let’s look at some of the standard SFP optics in today’s world.

1000BASE-T SFP: It is the SFP transceiver which is the RJ-45 version. We also call the rj45 sfp module. It operates up to 100m distances, on standard CAT 5 UPT copper cable link length.

1000BASE-SX SFP: It works on multi-mode fiber and operates up to 100 to 550m, using a 770 to 860 nm wavelength.

1000 BASE-LX SPF: This type of transceiver is implemented using either multi-mode or single-mode fiber-optic cabling, it could reach up to a maximum of 10 KM.  

1000 BASE-EX SFP: This type of transceiver is similar to 1000 BASE -LX but achieves a greater running speed of 1310 nm wavelength and a longer distance of 40 KM over single-mode fiber. It is also known as LH (Long Haul) which is a non-standard industry-accepted optic.

1000 BASE-ZX SFP: It uses the speed of 1550 nm wavelength and runs with a distances speed of 70-80 KM in just a single-mode fiber.

CWDM SFP Transceivers: type of optical transceiver that involves technology. Similar to any CWDM or SFP, it is also a cost-effective solution for adopting Fiber Channel and Gigabit Ethernet in data-center, campuses, and metropolitan-area access networks. It can also be found with a variety of transmitter and receiver types, to allow the appropriate transceivers to have each link provide the required optical reach.

DWDM SFP Transceiver: A term for Dense Wavelength-Division Multiplexing. Transceivers are also part of DWDM optical networks rendering BW with high performance across all-optical fiber networks. It is also a multi-range interface that supports any protocol from 100Mbps up to 4.25 Gbps.

SPF PLUS: It is an upgraded version of the SFP transceiver with higher data rates up to 16 Gbps. It is also a 10G fiber optic transceiver which is used for 10G Ethernet and Optical Transport Network. It also has the same dimension as regular SFPs.

Steps in Installing an SFP Transceiver:

  1. Remove the SFP module from the packaging without removing the dust plug.
  2. Verify the SFP transceivers label on the body, to confirm the accurate model required for the network.
  3. Find the location of send and receive markings that identify the top side.
  4. Remove the plugs from the SFP’s optical bores.
  5. Connect or attach the network interface cable connector to the SFP transceiver.
  6. Connect the SFP transceiver to your device.
  7. Check the port status LED.

Third-party manufacturers like QSFPTEK assure compatibility with the help of MSA standards. It helps SFP transceiver modules to have an open market. They are the one who ensures that the competing manufacturers can create an SFP that is compatible with work across multiple brands. With the help of MSA (Multi-Source Agreement), all the elements of both electrical and mechanical are specified, so that the users can feel confident that SFPs modules sold by vendors are identical and with the same standards in form of performance and factor to OEM top brands.

How do lock practices work? To answer that manufacturers from large industry, participate in vendor lock-in practices.
