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.
