The Cisco Line Card Expansion Module, part number 4OC3X/ATM-IR-SC, offers enhanced network performance and versatility with its 4-port configuration. This module is designed to expand the port capacity of compatible Cisco networking systems. Each port supports OC-3/STM-1 connections, which are commonly used for high-speed data communication over multi-service networks, enabling up to 155 Mbps throughput. The module uses a SC-type fibre optic connector interface, ensuring compatibility with standard optical network equipment.
The module is specifically configured for Asynchronous Transfer Mode (ATM) services, making it suitable for transporting data, voice, and video over a single network infrastructure. The support for multiple services in one line card enhances the scalability of network solutions by delivering high-speed connectivity and reliable performance. The use of OC-3 ports, which operate on the SONET/SDH standard, supports long-distance transmission applications, making it ideal for Service Providers or large enterprise networks.
Thanks to its robust specifications, this expansion module is an excellent choice for organisations needing high-bandwidth capabilities to handle increased data loads over fibre optic connections. It fits into Cisco networking platforms without requiring extensive configuration changes, further simplifying integration into existing systems while boosting performance with four additional ports.
