The Cisco 2-Port OC-3c/STM-1c POS Shared Port Adapter (SPA-2XOC3-POS) is an expansion module designed for high-performance network connectivity. This adapter features two OC-3c/STM-1c ports that enable Point-to-Point Protocol (PPP) or High-Level Data Link Control (HDLC) connections, which are commonly used for WAN forwarding and carrier networks. With support for Optical Carrier Level 3 (OC-3) and Synchronous Transport Module 1c (STM-1c), it provides reliable high-speed data transmission of up to 155.52 Mbps per port.
Its design follows the shared port adapter (SPA) architecture, meaning it delivers both scalability and flexibility through the Cisco SPA Interface Processor (SIP), which works with various Cisco networking devices. The adapter uses Packet-over-SONET (POS) technology that allows efficient encapsulation for IP and other network protocols over SONET/SDH networks. This makes the module particularly suited for provider edge routers and high-speed interoffice communication.
The SPA-2XOC3-POS supports single-mode fibre connections, offering durable and highly efficient optical links for long-distance data transfer. It is also compatible with various Cisco platforms, and overall network integration is streamlined thanks to the use of Cisco IOS software, delivering strong traffic management and protocol handling features.
In addition, the module supports hot-swapping, enabling network upgrades or changes without disruption to ongoing operations. Additionally, it is fully compliant with SONET and SDH standards, ensuring interoperability with a wide range of telecommunications infrastructure.
