Description
The LCP-1250B4MDRx is hot pluggable 3.3V
Small-Form-Factor transceiver modules designed
expressly for high-speed communication
applications that require rates up to 1.25Gb/s.
The transceiver is data rate transparent, which
means it can support GbE (1.25Gb/s) as well as
1x Fiber channel (1.062Gb/s) operations.

The post-amplifier of the LCP-1250B4MDRx
also includes a Loss of Signal (LOS) circuit that
provides a TTL logic-high output when the
received optical level is below a preset LOS
Assert threshold.
