The SO-CSFP-1000BASE-BX20D-43-O2 is a CSFP (Compact SFP) transceiver where both ports are bi-directional| i.e. providing
double capacity as compared to normal BiDi transceivers where one port is not used. This requires that the host equipment support
Each port operates directly on a single-fiber without the need for a separate optical filter. Each transceiver function uses a 1490nm
transmitter and a receiver operating at 1310nm. The solution requires that the far end host equipment uses bi-directional SFPs that
transmit on a 1310nm wavelength and a receiver that accepts a 1490nm wavelength.
The transceiver supports a bit rate range between 100 Mbps and 1.25 Gbps| e.g. 1G Fiberchannel (1G FC) 100M Ethernet (FE)
and 1G Ethernet (GbE) services| having an optical performance that provides a bridgeable distance of up to 20km.
The transceiver solution is available in two temperature range options| one being 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.
