2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA Overview
2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA Interface Specifications
The physical layer interface for the 2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA is Optical
Carrier-48 (OC-48), and provides SONET and SDH network connectivity with a per-port bandwidth of
2.488 Gbps.
2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA Cables, Optical Transceiver
Modules, and Connectors
Use single-mode (for intermediate-reach configurations) optical fiber cable to connect your router to a
network or to connect two 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:
•
Single-mode short-reach (SR) SFP module—SFP-OC48-SR
•
Single-mode intermediate-reach (IR) SFP module—SFP-OC48-IR1
•
Single-mode long-reach (LR) SFP module—SFP-OC48-LR2
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).
