APPLICATIONS
•
SONET OC-192 IR-2 Transmitter w/APD
SDH STM S-64.2b Transmitter w/APD
SDH STM S-64.3b Transmitter w/APD
ITU-T G.709 Transmitter w/APD
10GBASE-ER/EW Transmitter w/APD
10GBASE-ER/EW + FEC Tx w/APD
40km 10G Fibre Channel Transmitter
w/APD
Finisar’s 40km DWDM FTLX3912M3xx Small Form Factor 10Gb/s XFP transceivers
comply with the current XFP Multi-Source Agreement (MSA) Specification
1
. The
transmitter specification is based upon SONET OC-192 IR-2, OC-192 IR-3, SDH STM
S-64.2b, STM S-64.3b and 10-Gigabit Ethernet 10GBASE-ER/EW per IEEE 802.3ae but
uses an APD ROSA for additional link budget. Digital diagnostics functions are available
via a 2-wire serial interface, as specified in the XFP MSA. The optical transceiver is
compliant per the RoHS Directive 2011/65/EU
3
. See Finisar Application Note AN-2038
for more details
