This item is a Cisco Shared Port Adapter (SPA) that allows users to add four OC-3/STM-1 ports to their Cisco routers. These ports support synchronous optical networking (SONET) which is a standard for transmitting data over optical fibers at a rate of 155.52 Mbps. The SPA-4XOC3-POS-V2= is designed to be used with Cisco routers that support SPA interfaces and can be used to increase the number of available OC-3/STM-1 ports in a router. This increases the capacity of the network and allows for more connections to be made.

This SPA is often used by service providers to increase the capacity of their backbone networks, allowing for more efficient data transmission between different networks and locations. Additionally, it also supports POS (Packet over SONET) encapsulation, which enables it to transmit packet data over SONET networks. The V2 version of this device may have some additional features or improvements compared to the original version.

The SPA-4XOC3-POS-V2= is designed to provide high performance and reliability for service provider networks.

Performance-wise, the model provides four OC-3/STM-1 ports, each capable of transmitting data at a rate of 155.52 Mbps. This allows for a total of 622.08 Mbps of aggregate throughput when all four ports are utilized. This high-speed transmission capability makes the model well-suited for use in backbone networks, where large amounts of data need to be transmitted quickly and efficiently.

In terms of reliability, the model is built to meet industry standards for quality and durability. It is designed to operate in a wide range of temperatures and is built to withstand the rigors of a service provider environment. Additionally, the model supports various features that enhance its reliability such as hitless failover and fast convergence.

Cisco also provides regular software updates to improve performance and fix potential vulnerabilities. Additionally, Cisco provides technical support and service options to help ensure the model operates at peak performance and reliability.
