Description
The LCP-155A4HSRx series is 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) except for
TX fault function is not implemented.
The LCP-155A4HSRx 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-155A4HSRx
also includes a Loss Of Signal (LOS) circuit that
provides a TTL logic-high output when an
unusable optical signal level is detected.
The LCP-155A4HSRx transceiver is a Class
1 eye safety product. The optical power levels,
under normal operation, are at eye safe level.
Applications
SONET OC-3/SDH STM-1
ATM Network
Fast Ethernet
Switch to Switch interface
Switched backplane applications
File server interface
Performance
LCP-155A4HSR (H/T) Data Link up to 2km in
62.5/125µm Multi-Mode Fiber.
