RoHS Compliant Multirate Small Form Factor Pluggable Transceiver
for SONET OC-48/SDH STM-16 with Digital Diagnostic Function
Description
The LCP-2488A4EDRxM is hot pluggable
3.3V
Small-Form-Factor
designed expressly for high-speed communication
applications that require rates up to 2.5Gb/s. The
transceiver is data rate transparent, which means it
can comply with Gigabit Ethernet as specified in
IEEE Std 802.3 and Fibre Channel FC-PI 13.0.
They are compatible with SONET OC-48, SONET
OC-12 and SONET OC-3 standards.
The LCP-2488A4EDRxM is designed to be
compliant
with
SFF-8472
Agreement (MSA) with five digital monitoring
functions: Temperature, V
laser bias current, and RX received optical power.
The post-amplifier of the LCP-2488A4EDRxM
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.
