Xfp Connections - Cisco SCE 8000 Installation And Configuration Manual

Chapter 2 Introduction to the Cisco SCE 8000 10 GBE Platform

XFP Connections

The qualified XFPs include an optical transmitter and receiver pair integrated with Clock and Data
Recovery (CDR) integrated circuits. The XFPs provide high-speed serial links at 10.3125 Gbps on single
mode fibers.
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 laser, enabling data transmission over fiber through an LC connector. The
receive side recovers and retimes the 10 Gbps optical data stream from a photo detector trans impedance
amplifier and passes it to an output driver.
See the label on the XFP for technology type and model.
