2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA Cables, Optical Transceiver
Modules, and Connectors
Use single-mode optical fiber cable (for intermediate-reach configurations) to connect your router to a
network or to connect two OC-48-equipped routers back to back.
The 2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA supports the following types of optical
transceiver modules:
•
•
•
Each port on the 2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA has one duplex LC-type receptacle.
For single-mode optical fiber connections, you can use either a duplex LC-type cable (see
or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
