Cisco XFP Transceiver Module

The 10 Gbps 1310 nm XFP transceiver is an integrated fiber optic transceiver that provides high-speed serial link at the following signaling rates: 9.95 Gbps, 10.31 Gbps, 10.51 Gbps, and 10.66/10.71/11.10 Gbps. These rates apply to 10GBASE-LR (Fibre Channel and Ethernet) as well as OC-192/STM-64 SONET/SDH. The XFP integrates the receiver and transmit path. The transmit side recovers and retimes the 10 Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310 nm DFB (distributed feedback) laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10 Gbps optical data stream from a positive-intrinsic-negative (PIN) photo detector, transimpedance amplifier and passes it to an output driver.
