Description
The LCP-1250xxxx series are hot pluggable
3.3V Small-Form-Factor transceiver module
designed expressly for high-speed
communication applications that require rates of
up to 1.25Gbit/sec. It is compliant with the Gigabit
Ethernet standards, as well as the SFP
Multisource Agreement (MSA).
The LCP-1250xxxx 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-1250xxxx 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-1250xxxx transceiver is a Class 1
eye safety product. The optical power levels,
under normal operation, are at eye safe level.
z EEPROM with Serial ID Functionality
z Laser Class 1 Product which comply with the
requirements of IEC 60825-1 and IEC 60825-2
z Duplex LC Connector interface
Applications
z Gigabit Ethernet
z Fibre channel
z Switch to Switch interface
z Switched backplane applications
z File server interface
