ESR-4OC3ATM-SM-RF

The Cisco ESR-4OC3ATM-SM-RF is an expansion module specifically designed to enhance a compatible Cisco router’s network capacity and functionality. This module features four OC-3/STM-1 ports that are designed to support Asynchronous Transfer Mode (ATM) services. One of its key benefits is that it allows routers to significantly improve their high-speed data transmission capabilities, useful for organisations requiring large bandwidths for data-intensive applications.

The ESR-4OC3ATM-SM-RF module is a single-mode fibre type, enabling users to achieve high-speed connectivity over long distances. Single-mode fibre is particularly beneficial for wide-area network (WAN) connectivity, ensuring that the module is well-suited for enterprise and service provider environments that necessitate long-reach connections.

Furthermore, its support of ATM technology allows for versatile and reliable data transfer, making it an excellent solution for users who need efficient, high-capacity data handling across networks. This module comes with redundant interfaces, providing reliability and uptime, which are crucial for demanding environments where downtime is not an option.

Additionally, the Cisco ESR-4OC3ATM-SM-RF unit is a refurbished product, identified with the suffix "-RF", meaning it has been inspected, refurbished, and tested to ensure dependable performance in line with Cisco standards. This provides a cost-effective option for organisations aiming to expand their network hardware without compromising on network quality or reliability.
