Compare 3 SFP manufacturers: QSFPTEK, and

Optical transceiver (also known as the fiber module) is an indispensable part of the fiber optic communication network. With the large number of modules used in the network, the network budget is constantly increasing. So more and more customers tend to use relatively cheap third-party optical modules in the network. However, there are many different third-party transceiver vendors in the market, and the products offered vary in quality, price, service, and technical support. So how to choose the SFP manufacturers? In this article, we will give you an objective comparison of 3 of the historic SFP manufacturers right now which are QSFPTEK, and I hope it will be useful to you.


When choosing an SFP manufacturers, what should you pay attention to?

They should be qualified with industry certifications

The quality of your transceiver is the first factor you need to consider when choosing a qualified third-party module manufacturer. A reliable supplier of optical fiber transceivers is very strict with the manufacturing process from the input stage of material selection to product quality control process. In addition, the SFP modules they provide must conform to common industry certifications. For example ISO9001, CE (Construction Electrician), FCC (Federal Communications Commission), RHS (Restriction of Hazardous Substances) etc. What’s more, high-quality optical modules must go through TX/RX signal quality testing, spectrum evaluation test, reliability and stability test, and compatibility test before shipment. . Therefore, you should choose SFP manufacturers that fully provide the above test reports to be assured of quality.

Besides, the SFP manufacturer’s factory must ensure that there are three certificates, ISO9001, ISO14001, and TL9000. However, most third-party module sellers do not have their own module production line, and it seems most of them are looking for other manufacturers to make for them. Moreover, the third-party sellers do not know the process of the module, and the quality evaluation is limited to a few simple tests and customer feedback.

Provided with one-stop services

A reputable SFP provider will have a full service ecosystem for their customers to have the best experience. These include product service, technical support, ample inventory, and after-sales service.

Comprehensive Product Solution

Choosing a third-party transceiver supplier with comprehensive product solutions is essential. Because they can save you a lot of money. This criterion means that third-party module vendors have diverse product ecosystems. Not only do they offer different types of transceivers with different applications and data rates – like the 25G WDM transceiver used in the model. The 5G, 100G QSFP28 module is used in data centers or custom transceivers for special needs, but also provides other network components and equipment, such as Ethernet switches, cabling optical fiber, copper cable and the like to meet different network applications.

Have a professional technical support team

If you are a small to medium-sized business (SMB), the engineering team you own is unlikely to be able to design network topologies or plan network development. Then you should choose a supplier of optical transceivers with this to be able to provide technical support for you. It is essential when solving network problems or during maintenance and installation.

Efficient warehouse system

An SFP supplier with good warehouse management skills will deliver the products you need in a timely manner. Currently, most SFP vendors use automated processes to optimize product delivery. You must find out the storage capacity of your supplier’s warehouse to ensure that they service you timely.

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. Through the detection and settings in hardware and firmware, it detects a third-party transceiver and blocked it so won’t continue from working the device. They have been able to sustain the compatibility, many third-party SFPs are now equipped with the latest innovation.

The OEM manufacturers are now prohibited from voiding equipment warranties by Anti-competitive laws, due to the use of third-party transceivers. Users without the concern of compatibility issues can now confidently purchase the SFP.
