Specifications

Product Overview:

The Cisco WS-X2961-XL is an advanced ATM 155 Mbps multimode fiber uplink module designed to provide high-performance, fiber-based ATM connectivity for Cisco Catalyst 2900 XL Series switches. Featuring a standard SC connector for multimode fiber (MMF), this module enables long-distance, high-speed uplinks—ideal for enterprise backbones, inter-building connections, or integration into legacy ATM WAN infrastructures.
Built to support Asynchronous Transfer Mode (ATM) networks, the WS-X2961-XL provides quality-of-service (QoS) capabilities critical for voice, video, and data convergence. It supports industry standards such as ATM UNI 3.1/4.0, ILMI, and PVC (Permanent Virtual Circuits), making it a robust choice for organizations needing consistent and reliable ATM performance.
This plug-in module allows easy expansion without reconfiguring your entire infrastructure, offering excellent interoperability between legacy ATM networks and modern Layer 2 switching.
