1-Port 10-Gigabit Ethernet SPA Overview the other SPA pair may not use the excess bandwidth. When using a SIP with a PRE3, we recommend that you balance the overall SPA bandwidth between the top two SPA subslots and the bottom two SPA subslots. Also, install the SIPs in the outside slots of the chassis first.

1-Port 10-Gigabit Ethernet SPA XFP Optical Transceiver Modules, Connectors, and Cables
The 1-Port 10-Gigabit Ethernet SPA supports the following types of optical transceiver modules:
•
•
Single-mode short-reach (SR) XFP module—XFP-10GLR-OC192SR
Single-mode intermediate-reach (IR) XFP module—XFP-10GER-OC192IR
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of the above-listed small form-factor pluggable (XFPs) are the only optical transceiver modules qualified for use.
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.
XFP Connections
The XFP-10GLR-OC192SR and XFP-10GER-OC192IR XFP modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide high-speed serial links at the rate of 10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber

(SMF). 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 or 155-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector transimpedance amplifier and passes it to an output driver.
See the label on the XFP module for technology type and model.
Figure 3-4 shows an XFP module and
