X2 Transceiver is a kind of 10 Gbit/s fiber optic transceiver. Its development was based on former XENPAK standards. The X2 10 Gbit/s transceiver’s inner function is almost similar with XENPAK that also can use one transceiver to fulfill all 10 Gigabit Ethernet (10GbE) optical port function. X2 transceiver is about half size of XENPAK, which enables it suitable for density installations. X2 transceiver is a hot pluggable in the Z-direction module that is usable in typical router line card applications, Storage, IP network and LAN and compliant to XENPAK MSA. The XENPAK transceiver is a fully integrated 10.3 Gbit/s optical transceiver module that consists of a 10.3 Gbit/s optical transmitter and receiver, XAUI interface, MUX and DEMUX with clock and data recovery(CDR).
10GbE standards were defined by IEEE in 2002, it not only enlarges the data transmission rate, but it has greater working distance. IEEE 802.3ae 10GbE standard defined the working distance from 300 meters to 40km. We supply the X2 10G fiber optic transceivers that are fully compatible with equipment from other suppliers.
An X2 transceiver module uaually consists of these parts:
