Specifications

Product Overview:

The Cisco WS-X2972-XL is a premium ATM 155 Mbps long-reach single-mode fiber (SMF) uplink module designed for seamless integration with the Cisco Catalyst 2900 XL Series switches. Utilizing an SC connector, this module supports long-range fiber uplinks up to 40 km, enabling powerful connectivity across wide-area networks (WANs), inter-campus links, or remote branch sites.
Built to meet the demands of enterprise-grade ATM deployments, this module complies with ATM UNI 3.1/4.0 standards, and supports Permanent Virtual Circuits (PVC), ILMI, and QoS features for real-time voice, video, and mission-critical data traffic. Its 155 Mbps throughput over single-mode fiber ensures high-speed, low-latency communication over extended distances.
With its simple plug-in form factor and compatibility with VLAN-aware Catalyst switches, the WS-X2972-XL offers scalable fiber backbone connectivity, excellent EMI immunity, and investment protection for hybrid ATM-Ethernet infrastructures.
