APPLICATIONS
Amplified DWDM 10Gb/s SONET/SDH
w/FEC
Amplified DWDM 10Gb/s Ethernet
and 10Gb/s Fibre Channel w/FEC
Finisar’s FTLX4213x3xxxx Small Form Factor 10Gb/s (XFP) transceiver complies with
the XFP Multi-Source Agreement (MSA) Specification
1
. It supports amplified DWDM
10Gb/s SONET/SDH +FEC,10 Gigabit Ethernet +FEC, and 10 Gigabit Fibre Channel
+FEC applications over ~200km of fiber without dispersion compensation. The standard
product supports narrow tunability on the C- and L-Band channels with 50GHz spacing.
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

Notes:
1. Module circuit ground is isolated from module chassis ground within the module.
2. Open collector; should be pulled up with 4.7k – 10kohms on host board to a voltage between 3.15V
and 3.6V.
