The Cisco SPA-2XOC48POS/RPR is a 2-port, OC-48c/STM-16c Packet over SONET/DWDM (POS) and Resilient Packet Ring (RPR) Shared Port Adapter designed for high-performance data transport over SONET/SDH networks. This expansion module provides significant flexibility and scalability for service providers and enterprises aiming to optimise data traffic over long distances.
This adapter supports two optical interfaces, specifically engineered to handle OC-48c (SONET) and STM-16c (SDH) data rates. With these optical carrier levels, the Cisco SPA-2XOC48POS/RPR allows seamless integration into SONET-based metropolitan or global transport networks. Furthermore, the module supports POS, a protocol designed to map IP packets directly over SONET frames. This results in reduced protocol overhead and maximised data throughput.
Additionally, the hardware supports Resilient Packet Ring (RPR) technology, ensuring high availability and fault tolerance across the network. RPR is particularly well-suited for service providers looking to achieve 50ms failover times, critical for network uptime when handling time-sensitive applications, such as voice and video traffic.
The SPA-2XOC48POS/RPR is compatible with Cisco routers and can be deployed in environments that demand high data transmission speeds, such as data centres and large service provider infrastructures. The modular design of Cisco's SPA technology makes it well-suited for scalable deployments, offering hot-swappable capabilities to minimise downtime during upgrades or repairs.
EOL Technology supports the SPA-2XOC48POS/RPR by offering replacement parts, repair services, and professional assistance. Whether you need a replacement component for this expansion module or expert diagnosis and repair, EOL Technology provides the necessary support to ensure that your hardware continues to operate smoothly in its intended network environment.
