The SO-SFP28-BX40D-xxyy-I is a bi-directional transceiver solution operating directly on a single-fiber without the need for a separate optical filter. This is achieved by having two transceivers that inject different wavelengths into the same single-fiber. The solution thus consists of two transceivers; SO-SFP28-BX40D-2731 and SO-SFP28-BX40D-3127, operating at 1270nm and 1310nm respectively. Using a single-fiber solution provides a cost-efficient solution for interconnect and it simplifies the patching since no separate transmit/receive direction has to be taken into account.
The transceiver pair supports 25GbE and CPRI option 10 services, having an optical performance that provides a bridgeable distance of up to 40km.
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.
The transceiver solution is available in the Industrial temperature range (I-temp) of -40°C to +85°C (-40°F to +185°F). The transceivers provide digital diagnostic functions via a 2-wire serial interface as defined by the SFF-8472 specification.
