DESCRIPTION
General
Approved Optics 10GbE XENPAK transceiver module 0231A323-A 
is a hot pluggable in the highly integrated Serial optical transponder module for high-speed, 
10Gbit/s d a t a t r a n s m i s s i o n a p p l i c a t i o n s . That i s u s a b l e i n t y p i c a l 
r o u t e r l i n e c a r d applications, Storage, IP network and LAN and compliant to XENPAK 
MSA. The 0231A323-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). This transceiver line uses a cooled 1310 DFB Laser 
Diode to achieve 10K over standard single mode fiber as per 10GBASE-LR of the 
IEEE 802.3ae specification.
