The Way of Select Correct 100G QSFP28 Transceiver


With the quick development of optical communication, QSFP28 is considered to be the mainstream package of today’s 100G optical transceiver market. Users normally deploy and apply 100G optical transceivers on a large scale in data centers, Ethernet switches and so on, we might become confused when we are going to select right one for our equipment under a wide variety of QSFP28 transceivers. This article will focus on the way of select correct 100G QSFP28 transceiver module.


Fiber Type of 100G QSFP28

The maximum transmission distance of MMF optical transceiver module can reach 550m while the transmission distance of a SMF module can reach 10 km, 40 km, 80 km or even more.


The QSFP28 SR4 transceiver module supports links of 70m (OM3) and 100m (OM4) over multimode fiber with MPO connectors.


The QSFP28 LR4 transceiver module designs for use in 100G Ethernet links up to 10km on single-mode fiber.


Transmission Distances of 100G QSFP28

Different transceiver modules can reach corresponding transmission distance and the particular conditions and application will be fully mentioned below.


The QSFP28 SR4 transceiver module offers four independent transmit and receive channels, each capable of 25Gbps operation for an aggregated data rate of 100 Gbps, which is ideal for short distance telecom applications and rack to rack connections in the data center .


The QSFP28 LR4 transceiver module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. The transceiver supports link lengths of up to 10km over single-mode fiber at the wavelength 1310nm using a duplex LC connector.


Price of 100G QSFP28

Optical component of a single-mode optical transceiver module is twice as expensive as a multi-mode module, so it is slightly more expensive than a multi-mode optical transceiver module.


100G QSFP28 SR4 mentioned only needs US $130.00 which is relatively cheaper than other online shopping stores. all of our optical transceivers all 100% tested before selling and fully compatible with major brands such as Cisco, Huawei ,Juniper, Arista....


100G QSFP28 LR4 mentioned only needs US $948.10 which is also cheaper than other online shopping stores, Utoptical is always focusing on the R&D and production of optical modules with 100% good quality guarantee.


QSFP28 from Third-party

.As we know, purchasing QSFP28 transceiver from third-party source allows you to save much money especially when you are working with a limited budget , Sometimes you may do not how to select online shopping stores about optical transceiver modules, people tend to choose like Amazon Ebay ,however it is hard for people to get professional online store about Photoelectric products . In this case, you will be able to view Utoptial online shopping store about Photoelectric products.



Generally speaking, the short-distance transmission application for the multi-mode optical transceiver module, and the long-distance transmission application for the single-mode optical transceiver module .According to the above provided information and suggestion, you will be able to select the correct QSFP28 transceiver for your application. Utoptical offers a variety of 100G QSFP28 modules for both short reach, long reach applications at very economical prices which can satisfy your requirements .
