C85MS-4F-OC12SS

The Cisco Catalyst C8540 4-port OC-12 SMF-IR expansion module, identified by part number C85MS-4F-OC12SS, is designed to enhance the functionality of Cisco Catalyst 8540 systems. This module provides four OC-12 ports, which are capable of high-speed transmission over single-mode fibre (SMF). These ports are ideal for large networks requiring robust connections and reliable performance over longer distances, thanks to its use of intermediate range (IR) fibre optic technology.

Each of the OC-12 ports on the module supports data rates up to 622 Mbps, which delivers substantial bandwidth for demanding enterprise and service provider environments. This expansion card is appropriate for businesses seeking advanced capabilities in Wide Area Network (WAN) aggregation, enabling important organisational hubs or core routers to communicate over significant distances without sacrificing performance or reliability.

The expansion module fits seamlessly into Cisco's 8540 Series switches, delivering modular scalability to adapt to growing network demands. With these four ports, network administrators can easily incorporate high-bandwidth applications like video streaming, cloud services, or massive data transfers while maintaining efficient, reliable network operations. Its single-mode fibre (SMF) compatibility ensures that it works exceptionally well for deployments where long-term efficiency and low signal attenuation are critical factors.

This module also follows strict industry standards and is fully compatible with the relevant Cisco Catalyst systems, ensuring seamless reliability and integration into existing infrastructures. Organisations relying on scalable WAN connectivity will benefit from the ease and reliability of installing this module in their Cisco systems.
