those designed to support rates in the range of 10G cable

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 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 SFP+ Passive DAC 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.Fiber Optic Transceiver module is a self-contained component that can both transmit and receive. Each of these physical form-factors is defined in a standards document know assembly for superior as a Multi-Source Agreement, or MSA. Optical Transceivers types can be generally grouped into those supporting transmission speeds on the order of 1Gbps and those designed to support rates in the range of 10G cable. Optical transceivers form factors associated with 10Gbps transmission are: XFP, X2, XENPAK and SFP+ transceiver is a small form factor hot pluggable module designed for 10G network applications including 10G cable and fibre channel. XFP transceivers are with dual LC interface and the industrial acknowledged standards for XFP is called XFP MSA. XFP is a hot-swappable and protocol independent module
