XFP is a hot-swappable, low-circuit, serial-to-serial optical transceiver that supports SONET OC-192, 10Gbps Ethernet, 10Gbps Fiber Channel and G709 links. XFP's multi-source protocol (MSA) directly uses the XFI interface specification to define the power interface, which fully meets the limits of the SDH optical transport network. Compared to 1X9 and SFP modules, XFP has a higher transmission rate and transmission capacity, but also makes the application of Ethernet extended to the MAN and WAN.
The XFP package is smaller than the earlier XENPAK and X2 packages, XFP while the XENPAK & X2 optical modules are slightly larger than the size of the original small package pluggable optical module (SFP). XFP As shown in the following figure, the structure of the XFP contains five components:
1, the transmission rate of 9.953Gbps ~ 10.3Gbps
2, XFP standard package
3, double LC type, in line with hot-plug MSA standard
4, transmission distance support 300m-80km
5, support digital diagnostic function
XFP application scope
1,10 Gigabit / sec Ethernet
2,10 Gigabit / sec Fiber Channel
3, SONET OC-192
4, SDH STM-64
5, OTN OTU-2
6, parallel optical link
XFP is a low-cost WDM transmission technology for metro access layer. XFP uses CWDM technology, through the external wavelength division multiplexer, XFP the different wavelengths of optical signals together, through an optical fiber transmission, thereby saving fiber resources. At the same time, the receiver needs to use the wave demultiplexer to decompose the complex light signal. XFP is divided into 18 bands, from 1270nm ~ 1610nm, every two bands separated by 20nm.
XFP is the so-called Dense Wavelength Division Multiplexing (XFP) optical module. In particular, XFP dense wavelength division multiplexing technology, is a fiber optic data transmission technology, the use of laser wavelengths in accordance with the bit parallel transmission or character transmission in the fiber transmission within the data. DWDM optical module is for dense wavelength division multiplexing optical module, XFP it has 44 common channels can choose.
