Description and Specifications of Cisco XFP Module

The 10 Gbps 1310nm XFP transceiver is an integrated fiber optic transceiver and it provides high-speed serial link at the signaling rates: 9.95 Gbps, 10.31 Gbps, 10.51 Gbps, and 10.66/10.71/11.10 Gbps. These signaling rates apply to 10GBASE-LR (Fibre Channel and Ethernet) and 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 Single Mode Fiber (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.
