SFP28 25G/10G Ethernet 1310nm SM 10km 6.3dB LC

The SO-SFP28-LR is an SFP+ form-factor transceiver for 25 Gbps Ethernet applications. Since the transmission rate can reach up to 28Gbps, the engineering and industry name is SFP28. It is intended for use in interconnect applications between data centers with switches, routers, storage equipment etc.

The optical performance supports distances up to 10km over a SingleMode (SM) fiber. SO-SFP28-LR also supports the high data rate CPRI option 10 having a bit rate of 24.33024 Gbps. With the Clock and Data Recovery (CDR) functionality disabled, the transceiver can also be used for 10GbE-LAN and 10GbE-WAN services.

SO-SFP28-LR uses a single 1310nm channel @ 25.78 Gbps to transport a 25G Ethernet signal. As stipulated by the 25G Ethernet standards, Forward Error Correction (FEC) is required to be implemented by the host equipment in order to ensure reliable system operation.

The optical parameters below will provide a bit error ratio (BER) of 5 x 10-5 for 25G Ethernet. FEC will provide the required quality for secure service.
Digital diagnostics functions are available via an I2C interface, as specified by the MSA.
