RoHS Compliant Multi-Rate CWDM SFP Transceiver for Fast
Ethernet, ATM and SONET/SDH STM-1/OC-3 with DDM Function
Description
The LCP-155 CWDM series are designed for
coarse
wavelength
applications (CWDM) and hot pluggable SFP
transceiver modules that data rates up to 155 Mb/s.
The LCP-155 CWDM series are support Fast
Ethernet, ATM and OC-3/SDH STM-1 standards.
The selectiveness of center wavelength has 1470,
1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm.
The LCP-155 CWDM 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-155 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.
