Description 
The LCP-1250 CWDM series are designed 
for coarse wavelength division multiplexing 
applications (CWDM) and hot pluggable SFP 
transceiver modules that data rates up to 1.25Gb/s. 
The LCP-1250 CWDM series are support GbE 
(1.25Gb/s) and 1x Fiber channel (1.062Gb/s). The 
selectiveness of center wavelength has 1470, 
1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm.
The LCP-1250 CWDM series are designed to 
be compliant with SFF-8472 SFP Multi-source 
Agreement (MSA) with digital diagnostic 
monitoring functions: Temperature, V
CC
, TX 
optical power, TX laser bias current, and RX 
received optical power. 
The post-amplifier of the LCP-1250 CWDM 
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. 
Applications 
 
Gigabit Ethernet 
 
Switch to Switch interface 
 
Switched backplane applications 
 
File server interface
