XFP optical module fully complies with the XFP MSA standard of version 4.5 and the power consumption is less than 3.5W. The working rate of XFP module is from 8.5Gbps to 11.3Gbps, which is suitable for Sonet/SDH, 10G Ethernet, Fibre Channel and G.707 OTN standards. XFP 10G transceiver module adopts high-reliability laser and PIN or APD receiving components, laser driver and supporting circuit at the transmitting end. An avalanche photo-diode (APD) or PIN ROSA and supporting circuits are used at the receiving end. A clock data recovery circuit (CDR) is also provided. XFP 10G has digital diagnostics (also known as digital optical inspection, DDM), which monitors optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage in real time. Compliant with IEC 60825-1 Class 1/CDRH Class 1 Laser Eye Safe and RoHS directive. IT is suitable for switches, routers, firewalls and other equipment. Widely used in telecommunications, data centers, security and military industries.
