ESR-1OC12/P-SMI=

The Cisco ESR-1OC12/P-SMI= is an expansion module specifically designed for Cisco network hardware, providing a reliable solution for expanding network capabilities. This module supports OC-12/STM-4 interfaces, allowing it to deliver high-speed connectivity for enterprise and service provider environments. Its primary role is to extend the capabilities of a Cisco device by adding an optical interface for short-haul connections. The module is equipped with an SMI (Single-Mode Interface), ensuring compatibility with single-mode fibres, which are commonly used for long-distance data transmission due to their low attenuation and high capacity.

The ESR-1OC12/P-SMI= is designed for use in conjunction with Cisco's established networking products, ensuring that an organisation can easily scale its infrastructure to meet increasing data demands. As part of Cisco's comprehensive solution suite, this module provides compatibility with multiple OC-12 framing types and protocols, allowing for the seamless integration into high-performance networks. Due to its ability to operate within a variety of service provider environments, this module is ideal for expanding connectivity while maintaining robust performance and reliability.

Key specifications of the Cisco ESR-1OC12/P-SMI= include support for Packet over SONET/SDH (PoS) standards, which plays a critical role in optimising the transport of IP and other network layer protocols over optical networks. Additionally, the module enables up to 622 Mbps transfer rates, ensuring the delivery of high-bandwidth applications such as video streaming or large-scale data transfers. It also supports advanced error-checking mechanisms that enhance network reliability and uptime, which is crucial for mission-critical environments.
