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 Release 12.0(32)SY.
XFP Connections
The XFP-10GLR-OC192SR, XFP-10GER-OC192IR, and XFP-10GZR-OC192LR 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 the following rates: 9.95 Gbps (OC-192) and 10.3125 Gbps
(10 Gigabit Ethernet) 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 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 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
The XFP temperature range is 0°C to 70°C. For a picture of an XFP, see
