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
