RoHS Compliant Small Form Factor Pluggable Transceiver for Fast
Ethernet, ATM, SONET OC-3/SDH STM-1
FEATURES
Description
The LCP-155B4MSRx series are a hot
pluggable 3.3V Small-Form-Factor transceiver
module designed expressly for high-speed
communication applications that require rates of
up to 155Mbit/sec. It is compliant with the ATM,
SONET OC-3/SDH STM-1 standards, as well as
the SFP Multisource Agreement (MSA).
The LCP-155B4MSRx transceivers provide with
the LC receptacle that is compatible with the
industry standard LC connector. The transceiver
is also compatible with industry standard RFT
connector and cage.
The post-amplifier of the LCP-155B4MSRx also
include a LOS (Loss Of Signal) circuit that
provides a TTL logic-high output when an
unusable optical signal level is detected.
The LCP-155B4MSRx transceivers are a Class
1 eye safety product. The optical power levels,
under normal operation, are at eye safe level.
Compliant with SFP Transceiver MSA
