The Cisco 4-Port OC-48c/STM-16c POS/RPR Shared Port Adapter, with part number SPA4XOC48POSRPR-RF, is a versatile expansion module designed for high-performance networks. It features 4 ports that support both OC-48c (Optical Carrier Level 48) and STM-16c (Synchronous Transport Module Level 16) connections. These specifications are suitable for transmitting large volumes of data over fibre-optic networks at speeds up to 2.5 Gbps per port.
This Shared Port Adapter (SPA) provides high-speed Packet-over-SONET (POS) capabilities, enabling efficient communication over Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) protocols. The POS functionality ensures reliable, high-speed packet transmission through standardised, long-distance optical links. Additionally, the SPA supports Resilient Packet Ring (RPR) technology, which improves bandwidth efficiency while offering ring-based fault tolerance and network resilience. By leveraging RPR, the adapter can dynamically allocate bandwidth between ports, allowing for better utilisation of network resources, especially in metro Ethernet and carrier-grade infrastructures.
Designed to enhance modularity and scalability, the SPA is compatible with select Cisco routers that feature shared port adapter slots. It offers multiple configuration options to meet network expansion needs and operational flexibility. The unit helps maintain high network reliability and perform relevant optical diagnostics via built-in monitoring and status features.
