RoHS Compliant 4.25Gb/s Short Wavelength Tri-Rate SFP
Transceiver for Fiber Channel
Description
The LCP-4250A4CDR series are hot pluggable
3.3V Small-Form-Factor transceiver modules
designed
expressly
communication applications that require rates of
up to 4.25Gb/s. It is compliant with the Fiber
Channel standards FC-PI-2, as well as MSA
SFF-8472.
The LCP-4250A4CDR transceivers provide with
the LC receptacle that is compatible with the
industry
standard
transceiver is also compatible with industry
standard RFT connector and cage.
The post-amplifier of the LCP-4250A4CDR 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-4250A4CDR transceiver is a Class 1
eye safety product. The optical power levels,
under normal operation, are at eye safe level.
