2-Port OC48-POS/RPR SPA Interface Specifications
The physical layer interface for the 2-Port OC48-POS/RPR SPA is Optical Carrier-48 (OC-48), and the
2-Port OC48-POS/RPR SPA is designed to comply with POS specifications. The
2-Port OC48-POS/RPR SPA provides two 2.488-Gbps network interfaces for all supported platforms.
2-Port OC48-POS/RPR SPA Cables, Optical Transceiver Modules, and
Connectors
Use single-mode (for intermediate-configurations) optical fiber cable to connect your router to a network
or to connect two OC-48-equipped routers back-to-back.
The 2-Port OC48-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 OC48-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).
