RoHS Compliant SFP Transceiver for SONET OC-48/SDH STM-16 with
Digital Diagnostic Monitoring Function
Description
The
LCP-2488B4HDRx
pluggable
3.3V
Small-Form-Factor
modules
designed
communication applications that require rates up to
2.5Gb/s.
The LCP-2488B4HDRx 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-2488B4HDRx
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.
