What is XFP Optical Module?

XFP transceiver (10 Gigabit Small Form Factor Pluggable) is a hot-swappable optical transceiver, independent of the communication protocol, usually the size is 850nm, 1310nm or 1550nm for the 10G bps SONET / SDH, Fibre Channel, gigabit Ethernet, 10 gigabit Ethernet and other applications, including DWDM link. XFP contains similar SFF-8472 digital diagnostic modules, but extended to provide a robust management tools. XFI electrical interface specification is part of the XFP Multi Source Agreement specifications.

10G optical module will be the next few years, the most market potential for optical devices. Now used widely 10G optical module the following: 300pin, XENPAK, XPAK, X2 and XFP. Which 300pin belongs to the first generation of modules, mainly used in SDH electrical interface changed can also be applied to 10G Ethernet 10G Ethernet.

XENPAK is the launch of the first generation of 10G Ethernet optical module using the standard IEEE 802.3ae 10G additional unit interface (XAUI) as the data path; XPAK and X2, XENPAK optical modules directly improved version, about 40% smaller; XFP A compact, inexpensive optical modules, somewhat similar to the miniaturization of Gigabit Ethernet pluggable optical module (SFP).

10G 1310nm 10km XFP Optical Transceiver

Compared to other optical module, XFP transceiver, not optical transceiver module, transponder. The optical transceiver is actually just a photoelectric conversion device, only responsible for the completion of the optical / electrical signal conversion, other functions, such as multiplexing / demultiplexing, 64B/66B codec by the chip implementation of the circuit board. XFP optical module can easily achieve high port density applications, XFP occupied area of only the XENPAK the 20% of the printed circuit board (PCB), the power consumption is only 1.5 to 2 W, can be used to achieve up to 16-port line card.

With the rapid development of the fiber-optic network, the choice has entered 10G high-speed construction phase. The 10G XFP optical module, as the mainstream of high speed optical modules, is more and more widely used.
