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-10GZR-OC192LR
Cisco qualifies the optics that are approved for use with its SPAs. The above-listed small form-factor
pluggable modules (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 3-13 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
XFP Connections
The XFP-10GLR-OC192SR, XFP-10GER-OC192IR, and XFP-10GZR-OC192LR 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 1550-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 3-14 shows an XFP module and
Table 3-8 shows the XFP module specifications.
