About the Cisco SPA-2XOC3-POS Cisco Shared Port Adapter (SPA)
The Cisco SPA-2XOC3-POS is a Shared Port Adapter designed to integrate with Cisco 7600 Series and Cisco ASR 1000 Series routers, delivering dual-port optical connectivity for service provider and enterprise backbone networks. This single-wide SPA provides 2 ports operating at OC-3 / STM-1 line rates of 155.52 Mbps per port, enabling high-capacity SONET STS-3c and SDH STM-1 framing over SC duplex optical connectors. Part number SPA-2XOC3-POS supports Packet over SONET (POS) and HDLC encapsulation with RFC 2615 compliance for PPP over SONET/SDH deployments, ensuring standards-based interoperability across carrier-grade infrastructure.
Network engineers and infrastructure teams will appreciate the adapter's hot-swap capability and comprehensive diagnostic features, including internal and line loopback modes for in-service troubleshooting. The platform supports Cisco IOS, IOS XE, and IOS XR operating systems (dependent on platform), with integrated hardware-assisted QoS and MPLS functionality for dynamic traffic engineering and service differentiation. ITU-T G.707 compliant payload scrambling ensures signal integrity and compatibility with existing optical networks. Omnixon Global stocks the SPA-2XOC3-POS to support rapid deployment of mission-critical WAN and carrier access solutions across the Middle East and beyond.
Deployment Scenarios
- Service provider backbone interconnection and carrier handoff with redundant dual-port architecture
- Enterprise WAN acceleration and MPLS-enabled traffic engineering across geographically distributed data centers
- Legacy SONET / SDH network modernization with hot-swap field upgrades on active routers
- POS-based VPN aggregation and voice / video transport requiring deterministic QoS
- Network monitoring and diagnostics using internal and line loopback for non-disruptive testing
