The Cisco 8-port OC-12c/STM-4 Packet over SONET Shared Port Adapter, part number SPA-8XOC12-POS, is a highly functional expansion module designed specifically for high-speed data transfer over fibre-optic networks. It supports data rates of up to 622 Mbps per port, facilitating robust and reliable long-distance communications. This module is compatible with various Cisco router models, enhancing network infrastructure flexibility.
This expansion module provides a total of eight OC-12c/STM-4 ports, which comply with the SONET (Synchronous Optical Networking) and SDH (Synchronous Digital Hierarchy) standards used widely in telecommunications networks. Each of the eight ports supports Packet over SONET (POS), a method of transporting IP packets over optical fibre networks, ensuring efficient and scalable performance. The high port density allows for simultaneous usage while optimising physical space in the chassis.
The SPA-8XOC12-POS integrates easily into systems with shared port adapters, offering flexibility for network administrators. This integration, paired with its support for SONET and SDH functions, makes it a versatile asset in telecom and large enterprise network environments requiring high-speed, reliable data transmission. The use of shared port architecture provides optimal utilisation of resources while ensuring network sustainability and scalability.
Additionally, this shared port adapter utilises single-mode fibre, which extends transmission distances and is perfect for metropolitan networks. Hot-swappable, it allows engineers to replace or add the component without causing system downtime, which is essential for maintaining continuous communications in mission-critical environments. The Cisco SPA-8XOC12-POS thus offers a solid combination of performance, reliability, and ease of use.
