The Cisco SPA-2XOC3-POS is a high-performance Shared Port Adapter (SPA) designed for use in Cisco routers. It provides two OC-3/STM-1 (Optical Carrier level 3/Synchronous Transport Module level 1) ports for use with Packet-over-SONET/SDH (POS) networks. This enables high-speed data transfer between network devices such as routers and switches, delivering reliable and fast data transfer. The Cisco SPA-2XOC3-POS provides line-rate delivery of packetized voice and data services through the use of POS interfaces. This is an important feature for network providers that require high-capacity backbones for their services. The two OC-3/STM-1 ports on the SPA-2XOC3-POS can be used individually or aggregated for high-speed data transfer. One of the key benefits of the Cisco SPA-2XOC3-POS is its ability to support a range of optical interfaces, including short-reach, intermediate-reach, and long-reach. This enables network providers to choose the appropriate optical interface for their network requirements, ensuring high-speed data transfer over the desired distance. Additionally, the Cisco SPA-2XOC3-POS supports SONET/SDH protocols and provides support for ATM, Frame Relay, and High-Level Data Link Control (HDLC) protocols. This enables network providers to easily integrate the SPA-2XOC3-POS into their existing network infrastructure. Overall, the Cisco SPA-2XOC3-POS is a reliable and high-performance Shared Port Adapter that is ideal for use in Cisco routers. Its ability to support multiple optical interfaces, provide line-rate delivery of packetized voice and data services, and support a range of network protocols make it a solid choice for network providers looking to improve their network infrastructure.
