1-Port OC-48/STM-16 POS SPA Optical Transceiver Modules, Connectors, and
Cables
The 1-Port OC-48/STM-16 POS SPA uses a single-mode, 9.95 Gbps, OC-48 optical fiber (SONET STS-48)
optical transceiver module for SONET connection to the network.
The 1-Port OC-48/STM-16 POS SPA supports the following type of optical transceiver module:
•
•
•
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.

connections.

Mate Interface Cables

The 1-Port OC-48/STM-16 POS SPA supports two mate interface configurations:
•
•
Two 1-Port OC-48/STM-16 POS 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 2-42 shows the mate cables used to
connect the SPAs.
