eliminating the necessity to reinstall on 10G cable

 XFP 10G cable is a type of 10 Gigabit Ethernet optical transceiver. X2 transceiver is based on Xenpak transceiver module, and it has same function with Xenpak transceiver. X2 Module also can use one transceiver to fulfill all 10G Ethernet optical port function. X2 Transceiver is better for density installation for it is only half size of Xenpark transceivers.Its electrical interface for that host board can also be standardized and it is called XAUI (4 x 3.125 Gb/s).10G cable is a highly integrated, Serial optical transponder module for high-speed, 10Gbit/s data transmission applications.

Xenpak transceiver is packed in a 4.8 x 1.4 x 0.7 inch package, use DFB laser components, Xenpak working distance via G652 multimode fiber could reach up to 10km, another important components inside the Xenpak is the MUX/DEMUX parts, it consume 50% of the power and result in the bigger size. XENPAK modules are offered for physical layer interfaces supporting multi-mode and single mode fiber optic cables and InfiniBand copper cables InfiniBand Cables  with connectors referred to as CX4. Transmission distances vary from 100 metres (330 ft) to 80 kilometres (50 mi) for fiber and as much as 15 metres (49 ft) on 10G cable. Newer XENPAKs while using 10GBase-LX4 standard operated using multiple wavelengths on legacy multi-mode fibres at distances of up to 300 metres (980 ft), eliminating the necessity to reinstall cable in a building when upgrading certain 1 Gbit/s circuits to 10 Gbit/s.
