10G X2 Transceiver
The 10G X2 Transceiver is a type of 10Gigabit Ethernet optical transceiver based on Xenpak Transceiver Module. X2 Module also can use one transceiver to fulfill all 10G Ethernet optical port function or 10G Fiber Channel versions. X2 Transceiver is better for density installation for it is only half size of the old generation Xenpark Transceiver Module. It is electrical interface for that host board can also be standardized and it is called XAUI (4x3.125Gb/s). Manufactures can supply X2 220m, X2 300m, X2 10km, X2 20km, X2 40km, X2 80km optical modules and all modules support Digital Optical Monitoring (DOM) function.
