2-Port and 4-Port OC-48/STM-16 POS SPA Overview
2-Port and 4-Port OC-48/STM-16 POS SPA Interface Specifications
The physical layer interface for the 2-Port and 4-Port OC-48/STM-16 POS SPA is Optical Carrier-48
(OC-48), and provides SONET and SDH network connectivity with a per-port bandwidth of 2.488 Gbps.
Each port on the 2-Port and 4-Port OC-48/STM-16 POS SPA has one duplex LC-type receptacle that
allows connection to single-mode optical fiber.
2-Port and 4-Port OC-48/STM-16 POS 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 OC-48-equipped routers back-to-back.
The 2-Port and 4-Port OC-48/STM-16 POS SPA supports the following types of optical transceiver
modules:
•
Single-mode short-reach (SR) SFP module—SFP-OC48-SR OC48/STM16c
•
Single-mode intermediate-reach (IR) SFP module—SFP-OC48-IR1 OC48/STM16c
•
Single-mode long-reach (LR) SFP module—SFP-OC48-LR2 OC48/STM16c
Each port on the 2-Port and 4-Port OC-48/STM-16 POS 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).
