Different Angles To Understand XFP Transceiver


What is the XFP Transceiver?

The XFP transceiver (10 Gigabit Small Form Factor Pluggable) is a standard optical transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical component switch is called XFI. A XFP module is a device comprising both a transmitter and a receiver which are combined and share common circuitry or a single housing.

The XFP Transceiver Development

The XFP specification was developed by the XFP Multi Source Agreement Group. It is an informal agreement of an industry group, not officially endorsed by any standards body. The first preliminary specification was published on March 27, 2002. The first public release was on July 19, 2002. It was adopted on March 3, 2003, and updated with minor updates through August 31, 2005.

The XFP Transceiver Detail Info

1. XFP modules are hot-swappable and protocol- independent.

2. They typically operate at optical wavelengths (colors) of 850 nm, 1310 nm or 1550 nm.

3. Principal applications include 10 Gigabit Ethernet, 10 Gbit /s Fibre Channel, Synchronous optical networking (SONET) at OC-192 rates, Synchronous optical networking STM-64, 10 Gbit /s Optical Transport Network (OTN) OTU-2, and parallel optics links.

4. They can operate over a single wavelength or use dense wavelength-division multiplexing techniques.

5. They include digital diagnostics that provide management that were added to the SFF-8472 standard.

6. XFP modules use an LC fiber connector type to achieve high density.

The XFP Transceiver Accessories

The XFP product line is designed to support 10 Gigabit Fibre Channel, 10 Gigabit Ethernet and OC192/STM-64. Constructed from a metal frame, the cage assembly is designed to be bezel-mounted to an I/O panel with compliant pins for pressing onto the host PCB. The cage assembly features four EMI gaskets, which block any EMI emissions emanating from the transceiver when installed. The front flange provides a flat surface to contact the EMI gasket (attached to the perimeter of the bezel cutout) and stabilizes the cage assembly during insertion and extraction of the transceiver. Heat sinks are optional for applications requiring increased heat dissipation and are attached to the cage assembly using a clip.

The XFP Transceiver Work

XFP modules 10Gb/s (XFP) transceivers are compliant with the current XFP Multi-Source Agreement (MSA) Specification. XFP modules typically operate at near-infrared wavelengths (colors) of 850 nm, 1310 nm or 1550 nm. Principal applications include 10 Gigabit Ethernet, 10 Gbit/s Fibre Channel, OC-192 rates, STM-64, 10 Gbit/s Optical Transport Network (OTN) OTU-2. FiberStore provide a full range of XFP Modules, including DWDM XFP, CWDM XFP, BiDi XFP,10G XFP and compatible Cisco XFP, Juniper XFP, Brocade XFP, ect.
