Cisco ESR-6OC3/P-SMI : 6 Port OC3/STS3c/STM1c POS Line Card, single mode

The Cisco 10000 Series six-port OC-3c/STM-1 POS line card is a high-capacity, high-performance interface that enables service providers to offer dedicated Internet access services and peering to other service providers at OC-3c/STM-1 rates. With its line-rate OC-3c/STM-1 capacity (155 Mbps), this Cisco 10000 Series module provides a powerful combination of scalability and flexibility - enabling service providers to substantially increase the data load over their optical transport infrastructure.

The Cisco 10000 Series six-port OC-3c/STM-1 PoS card provides the unique advantages of efficient bandwidth utilization combined with line-rate performance.

A major advantage of mapping IP packets directly into SONET/SDH technology is the ability to provide superior performance. OC-3c/STM-1 line-rate performance of 155 Mbps provides the increased bandwidth required by many ISPs to handle the most demanding user requirements such as faster access to the Internet and data-intensive applications such as real-time video and large file transfers.
