SFP28 25G/10G Ethernet 850nm MM 1.9dB 100m LC
A dual-protocol SFP28 transceiver for 25G and 10G Ethernet applications
Product information
The SO-SFP28-SR is an SFP+ form-factor transceiver for 25Gbps Ethernet applications. Since the transmission rate can reach up to 28Gbps, the engineering and industry name is SFP28. It is intended for use in inter- and intra-connect applications within data centers between switches, routers, storage equipment etc. The optical performance is in accordance with the IEEE -SR standard, i.e. for optical distances up to 100m over a MultiMode (MM) OM4-grade fiber.
With the Clock and Data Recovery (CDR) functionality disabled, the transceiver can also be used for 10GbE-LAN and 10GbE-WAN services.
SO-SFP28-SR uses a single 850nm channel @ 25.78 Gbps to transport a 25G Ethernet signal. Digital diagnostics functions are available via an I2C interface, as specified by the MSA.
As stipulated by the 25G Ethernet standards, Forward Error Correction (FEC) is required to be implemented by the host to ensure reliable system operation. The optical parameters below will provide a bit error ratio (BER) of 1 x 10-5 for 25G Ethernet. FEC will provide the required quality for secure service.
