Introduction to the Cisco SCE8000 10GBE Platform

Figure 2-5

The interface connector on the 1-Port 10-Gigabit Ethernet SPA is a fiber optic receiver that supports one

XFP.

The types of optics modules that have been qualified for use with the 1-Port 10-Gigabit Ethernet SPA on

the Cisco SCE8000 platform are as follows:

•

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.

XFP dimensions are:

•

The XFP operating temperature range is 0°C to 70°C.
