The SFP28 optical transceiver module is mainly used for the interconnection of data center servers and switches. It is a new Ethernet standard with multiple advantages. It was proposed by the IEEE 802.3 working group and was completely revised in 2016. The advantage of 25G SFP28 optical transceiver module Ethernet technology is that it can maximize bandwidth and port density. It can achieve 100Gb data transmission through 25Gb/s single-channel physical layer technology.

The best input/output (I/O) performance and fiber capacity of the SFP28 optical transceiver module is 2.5 times that of 10G Ethernet, and it has a higher port density. It can also save operating costs by reducing the number of TOR switches and cables. Compared with 100G optical transceiver module, the loss of 25G SFP28 optical transceiver module is also smaller.
SFP28 optical transceiver modules can be used in high-density 25G Ethernet switch and network interfaces, thus providing operators with a more cost-effective solution for upgrading 10G Ethernet. The QSFP28 optical transceiver module can provide four 25Gbps high-speed signal channels, and is applied to high-density 25G Ethernet switch and network interfaces, providing a smooth upgrade possibility for data centers to further evolve to 100Gbps Ethernet (4x25Gbps).
According to different transmission rates, optical transceiver module can be divided into 1G optical transceiver module, 10G optical transceiver module, 25G optical transceiver module, 40G optical transceiver module, 100G optical transceiver module and 400G optical transceiver module.

25G optical modules are roughly divided into three types, 25G dual-fiber modules, 25G WDM modules, and 25G BIDI modules
100G SR4 multi-mode optical modules can be used for interconnection. Under the premise of equipment support, 100G QSFP28 ports can be configured as 4*25G mode, and then MPO-LC fiber jumpers are used to connect 100G SR4 optical modules and 25G SFP28 optical modules.
At present, 25G SFP28 optical modules can transmit up to 40 kilometers. There are 25G SFP28 ER, 25G SFP28 bidi, 25G SFP28 CWDM, and 25G SFP28 DWDM.
The power consumption of this module <1w.
It plugs in, it just works. No mess, no fuss.
Unbeatable price and delivery time
I bought two of these transceivers to connect two switches together and I have to say It was never so easy my first time with fiber
Works great! Ships the same day.
The transceiver works just fine, I installed it, connected it and the link was up and running.
