Description 
The LCP-1250B4QDRx series are 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 LCP-1250B4QDRx series are designed 
to be compliant with SFP Multi-source Agreement 
(MSA).  Digital diagnostic monitoring functions 
(Temperature, V
CC
, TX optical power, TX laser 
bias current, and RX received optical power) 
compliant with SFF-8472 are also available.    See 
order information for details. 
The post-amplifier of the LCP-1250B4QDRx 
series 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.
