RoHS Compliant Multimode SFP Transceiver for GbE and Fiber
Channel
Description
The
LCP-1250A4FDRx
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-1250A4FDRx series are designed to
be compliant with SFF-8472 SFP Multi-source
Agreement
(MSA)
monitoring functions: Temperature, V
optical power, TX laser bias current, and RX
received optical power.
The post-amplifier of the LCP-1250A4FDRx
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.
