In computer networking, we know that 10 gigabit Ethernet (10GE or 10GbE or 10 GigE) refers to various technologies for transmitting Ethernet frames at a rate of 10 gigabits per second (10×109 or 10 billion bits per second), first defined by the IEEE 802.3ae-2002 standard. This article introduces 10G SFP+, Xenpak, X2 and 10G XFP transceiver module for 10 Gigabit Ethernet deployments.
Xenpaks are supported on routers and some Catalyst switches. The small form-factor X2 modules are supported on the Catalyst Switches. XFP modules are supported on routers with Shared Port Adapter (SPA).They provide customers a dual-rate interface for 10 Gigabit Ethernet and Packet-over-SONET/SDH (POS) connectivity.
10G SFP+ Transceiver Module
10G SFP+ transceivers are designed for the high performance integrated duplex data transmission over single mode optical fiber. The improved small form-factor pluggable(SFP+) is definitely an enhanced version of the SFP that supports data rates as much as 10 Gbit/s, the newest industry format supported by many network component vendors. The 10GBASE SFP+ modules offer customers a wide variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closet, and service provider transport applications.
10G X2 Transceiver Module
10G X2 Module 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 XENPAK Transceiver Module
10G XENPAK Module 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 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 CX4 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.
10G XFP Transceiver Module
The 10GB XFP transceiver module is a hot-swappable I/O device that plugs into 10-Gigabit ports. The XFP is a standard for transceivers for high-speed computer network and telecommunication links which use optical fiber, and its interface to other electrical components which is called XFI. XFP modules typically operate at near-infrared wavelengths (colors) of 850 nm, 1310 nm or 1550 nm.XFP modules make use of an LC fiber connector type, which makes it easily achieve high port density applications.
