RoHS Compliant 8.5Gb/s Short Wavelength SFP+ Transceiver
Description
The LCP-8500A4EDR is hot pluggable 3.3V
Small-Form-Factor transceiver modules designed
expressly
for
high-speed
applications that require rates of up to 8.5Gb/s.
It is compliant with SFP+ MSA, SFF-8431
specification and Fiber Channel FC-PI-4, as well as
MSA SFF-8472.
The LCP-8500A4EDR transceivers provide with the
LC receptacle that is compatible with the industry
TM
standard LC
connector. The transceiver is also
compatible with industry standard RFT connector
and cage.
The post-amplifier of the LCP-8500A4EDR 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-8500A4EDR transceiver is a Class 1
eye safety product. The optical power levels,
under normal operation, are at eye safe level.
