1 Port 10-Gigabit Ethernet SPA Overview
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
• Single-mode very-long-reach (ZR) XFP module—XFP-10GER-OC192LR
• Multi-mode short reach (SR) XFP module—XFP-10G-MM-SR
Cisco Systems qualifies the optics that are approved for use with its SPAs. As of Cisco IOS XR
Release 3.4.1, 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.
Figure 2-10 shows the cable
type for use with the XFP optical transceiver module on the 1-Port
10-Gigabit Ethernet SPA.

Note The 40-pin connector on the 1-Port 10-Gigabit Ethernet SPA is used for resilient packet ring (RPR)
connections. This feature is not supported in Cisco IOS XR Release 4.3.0.
XFP Connections
The 10GLR, 10GER, and 10GZR 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
Green On SPA is ready and operational.
Amber On SPA power is on and good, and the SPA is being configured.
