DWDM 80km 10G Ethernet
DWDM 80km 10G Fibre Channel
DWDM 80km 10G Ethernet with FEC
Finisar’s 80km FTLX3811M3xx Small Form Factor 10Gb/s (XFP) transceivers comply with the
current XFP Multi-Source Agreement (MSA) Specification
1
. They exceed the requirements for
DWDM 10Gb/s SONET/SDH interfaces per ITU-T G.698.1 S-D100S1-2D, and support DWDM
10-Gigabit Ethernet, 10-Gigabit Fibre Channel, and 10-Gigabit Ethernet with FEC applications.
Digital diagnostics functions are available via a 2-wire serial interface, as specified in the XFP
MSA. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC
3
, and Finisar
Application Note AN-2038
