Chapter 2 Introduction to the Cisco SCE8000 Platform
Introduction to SIPs and SPAs
Modular Optics
The SPAs implement 10GBE small form-factor pluggable (XFP) optical transceivers to provide network
connectivity. An XFP module is a transceiver device that mounts into the front panel to provide network
connectivity.
Note It is highly recommended only to use the XFP modules listed as supported in this document. Use of
unsupported or unqualified XFP modules may affect reliability or operation.
Figure 2-5 10GBE Small Form-factor Pluggable (XFP0)
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-10GLR-OC192SR
• XFP-10GER-OC192IR
• XFP-10GZR-OC192LR
• XFP-10G-MM-SR
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:
• Height 12.5 mm
• Width 18.35 mm
• Length 71.1mm
