2-Port and 4-Port OC-48c/STM-16 POS SPA Interface Specifications

The physical layer interface for the 2-Port and 4-Port OC-48c/STM-16 POS 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 SPA has one duplex LC-type receptacle that
allows connection to single-mode optical fiber.
For Cisco IOS XR Software Release 3.8.0, the 2-Port and 4-Port OC-48c/STM-16 POS SPA supports
Note
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.
