Description
The LCP-155A4HSRBx series are hot pluggable
3.3V Small-Form-Factor transceiver module designed
for high-speed communication applications that require
rates of up to 155Mbit/sec. It is compliant with the Fast
Ethernet standards, as well as the SFP Multisource
Agreement (MSA).
The LCP-155A4HSRBx 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-155A4HSRBx also
includes a LOS (Loss Of Signal) circuit that provides a
TTL logic-high output when an unusable optical signal
level is detected.
The LCP-155A4HSRBx transceiver is a Class 1
eye safety product. The optical power levels, under
normal operation, are at eye safe level.
Applications
100Base Fast Ethernet
Switch to Switch interface
Switched backplane applications
File server interface
