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), which 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-48c/STM-16 POS/RPR SPA has one duplex LC-type receptacle
that allows connection to single-mode optical fiber.
Note For Cisco IOS XR Software Release 3.8.0, the 2-Port and 4-Port OC-48c/STM-16 POS/RPR SPA
supports Dynamic Packet Transport (DPT) feature. Cisco DPT family of products delivers scalable
Internet service, reliable IP-aware optical transport, and simplified network operations. The Spatial
Reuse Protocol (SRP) is a MAC-layer protocol developed by Cisco and is used in conjunction with Cisco
DPT products, which utilizes a pair of counter-rotating rings in an optimum fashion to provide improved
bandwidth utilization over an equivalent SONET network.
