 25G SFP28 optical transceivers

LANMexx’s 25G SFP28 optical transceivers include SR, LR commercial-temperature series, and SR, LR,CWDM industrial-temperature series. IEEE802.3by and SFF-8472 compliant, low power consumption.They are designed for applications of Data Center, 5G network, 25G Ethernet and Fiber Channel. 

25G fibre channel transceivers that are SFP compliant. This fibre channel transceiver solution supports high-speed serial links

over multimode optical fiber at signaling rates up to 25 GBd.Using the 2-wire serial interface defined in the SFF-8472 MSA,

these 25G fibre channel transceivers provide real-time temperature, supply voltage, laser bias current, laser average

output power and received input power.Compliant with Small Form Pluggable (SFP) Multi Source Agreement (MSA) mechanical and electrical specifications for LC Duplex transceivers, Fibre Channel transceiver for FC-PI-5 and FC-PI-2 gigabit applications.

Fibre Channel Protocol (FCP) is a transport protocol (similar to TCP used in IP networks) that predominantly transports SCSI commands over Fibre Channel networks.The fibre channel protocol has a rich roadmap of speeds on a variety of underlying transport media. For example, the following table shows native fibre channel speed variants
