The Basic Principles Of XFP

- Jun 15, 2017-


The advantages of the XFP optical module are mainly due to the faster transmission speed, support 10 Gbps Ethernet transmission, but the volume is larger than the SFP + optical module, so no SFP + optical module is popular. Source (Fast Fiber)

XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable, independent communication protocol optical transceiver, usually the wavelength of the transmission of light is 850nm, 1310nm or 1550nm, for 10Gbps SONET / SDH, Fiber Channel , Gigabit Ethernet, 10 gigabit Ethernet, XFP and other applications, including DWDM links. The XFP contains a digital diagnostic module similar to SFF-8472, XFP but has been extended to provide a powerful diagnostic tool.

XFP (miniaturized hot-swappable) optical module and the basic principles of optical transceiver module design, using the CDR (clock data recovery), APC (automatic power control), LA (limiting amplifier) and launch driver integrated main chip GN2010EA, compared with the traditional design not only reduces the design costs, but also reduces the complexity of the design. The test results show that the module can maintain a stable optical power and extinction ratio over a wide temperature range, XFP and meet the requirements of the ITU-T standard and meet the 10 Gbit / s optical module design requirements.

The basic principles of XFP optical modules, low-cost design, and related testing (feasibility of verifying solutions). This design uses CDR (clock data recovery), APC (automatic power control), LA (limiting amplifier) and driver integrated master chip GN2010EA, reducing the number of devices, XFP reducing the difficulty of making the process to achieve a low cost The
