1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Overview
1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA Fixed Optical Transceiver,
40-Pin Connector, and Cables
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses fixed optical transceivers, one for receive
(RX) and one for transmit (TX), for SONET and SDH connection to the network. Only Very Short Reach
(VSR) optics are supported.
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA uses multimode MTP-type connectors:
• Multimode—9.95 Gbps, OC-192 optical fiber (SONET STS-192c or SDH STM-64c)
Use a multimode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns. (Nominal
diameter is approximately 10/125 microns.)
Use a multimode optical fiber cable to connect your router to a network.
Figure 3-29 shows the cable type for use with the fixed optic transceiver module on the 1-Port
OC-192c/STM-64 POS/RPR VSR Optics SPA.

Note The 40-pin connector on the 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA is used for resilient
packet ring (RPR) connections. Support for the RPR feature is dependent on the platform software
release feature content. Verify support for the RPR feature using SPA datasheets or by contacting your
Cisco representative.
Mate Interface Cables
The 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPA supports two mate interface configurations:
• Mate between two OC-192c SPAs in the same SIP
• Mate between two OC-192c SPAs in adjacent SIPs
Two 1-Port OC-192c/STM-64 POS/RPR VSR Optics SPAs are connected using a 40–pin connector
copper mate cable. The length of the cables allow only two possible connection scenarios, next slot
horizontal and same slot vertical. This assumes that the chassis is mounted vertically.
Figure 3-30 shows
the mate cables used to connect the SPAs.
