2-Port OC-48 POS/RPR SPA Overview
1-Port OC-48c/STM-16 ATM SPA Interface Specifications
The physical layer interface for the 1-port OC-48 ATM SPA is Optical Carrier-48 (OC-48), and the
1-port OC-48 ATM SPA is designed to comply with ATM specifications. The 1-port OC-48 ATM SPA
provides one 2.488-Gbps ATM network interface for all supported platforms.
Each 1-port OC-48 ATM SPA has one duplex LC-type receptacle that allows connection to single-mode
optical fiber.
1-Port OC-48c/STM-16 ATM SPA Cables 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 SPA-OC48 accepts an SFP module with a duplex LC-type receptacle that allows connection to
single-mode optical fiber. For single-mode optical fiber connections, you can use either a duplex
LC-type cable (see
Figure 3-19) or two simplex LC-type cables, one for transmit (TX) and one for
receive (RX).
