RoHS Compliant Single Mode SFP Transceiver for GbE and Fiber
Channel
Description
The
LCP-1250B4QDRx
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
(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
, TX optical power, TX laser
CC
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.
