XFP optical module and other modules of different Jul 06, 2016

XFP optical module (10 Gigabit Small Form Factor Pluggable) is a hot-swappable, communication protocol-independent optical transceiver, size is usually 850nm, 1310nm or 1550nm, for 10G bps SONET/SDH, fibre channel, Gigabit Ethernet,10 Gigabit Ethernet and other applications, including DWDM links. XFP module includes digital Diagnostics similar to SFF-8472, but has been expanded, provides a robust management tool. XFI electrical interface specification is part of the XFP Multi Source Agreement specification. XFP developed by the XFP Multi Source Agreement Group.
Compared with several other modules, XFP optical transceiver device (Transceiver), not optical transceiver module (Transponder). Optical transceivers is really just a photoelectric conversion device, only responsible for optical/electrical conversion, other functions such as multiplexing/demultiplexing, 64B/66B codecs, etc by chip on the circuit board. XFP optical modules for easy application of high port density, occupied as XFP printed circuit board (PCB) area only Xenpak 20%, only 1.5~2 w power consumption, so it can be used for up to 16-port line card.
XFP optical module and interface with 10G serial interface circuit of the circuit board (XFI). Now manufacturers offer XSBI-to-XFI and XAUI-to-XFI chips, chip manufacturers in the development of the XGMII-to-XFI.
XFP optical transceiver, so a protocol-independent, can be widely applied to 10G OC-192 SDH and Ethernet, 10GFC, universality of application to equipment manufacturers to improve procurement, so as to achieve the purpose of reducing costs. In addition, the XFP provides a two-wire serial interface, you can implement data Diagnostics, real-time monitoring of optical module parameters, such as temperature, laser bias current, sending optical power, received optical power, voltage, etc.
