The Cisco 1-Port OC48c/STM16c POS/RPR Shared Port Adapter, part number SPA-1XOC48POS/RPR, is a high-performance expansion module designed to support both packet-over-SONET (POS) and Resilient Packet Ring (RPR) protocols. This shared port adapter (SPA) is engineered to provide reliable, high-speed connectivity at the OC-48c (2.5 Gbps) or STM-16c rates, ensuring an efficient data transfer across wide-area networks (WANs) and metropolitan area networks (MANs).
The adapter supports multiple encapsulation types, including both Point-to-Point Protocol (PPP) and High-Level Data Link Control (HDLC), enhancing its versatility for different network types. The module is designed with one optical connector, utilising a Small Form-Factor Pluggable (SFP) transceiver, which allows the user to easily replace or upgrade optical components as needed depending on network requirements.
Its ability to handle both POS and RPR traffic enables the SPA to be used in a wide variety of network topologies — from point-to-point connections in fibre-optic systems to more complex ring configurations for added redundancy and efficiency. The use of RPR technology ensures a robust design optimised for self-healing ring structures, critical for maintaining network resilience in case of failures.
Another key feature of the Cisco SPA-1XOC48POS/RPR is its integration with Quality of Service (QoS) mechanisms, providing traffic prioritisation to meet the demands of voice, video, and data convergence in enterprise and service provider networks. The module is hot-swappable, allowing you to add or replace it without interrupting system operations, thus ensuring minimal downtime.
