General Description
Approved Optics 10Gb/s X2 transceiver module J8437A-A is a hot pluggable 
module that is usable in typical switch or router line card applications that are 
compliant to X2 MSA standards. The J8437A-A is a fully integrated 
10.3Gbit/s optical transceiver module that consists of a 10.3Gbit/s optical 
transmitter and receiver, XAUI interface, Mux and Demux with clock and data 
recovery (CDR). The J8437A-A transceiver uses an uncooled 1310nm DBF 
Laser Diode to achieve 10km over standard single mode fiber as per the IEEE 
802.3ae specifications.
