Cisco CRS-4-FC CRS-4-FC Switch Fabric Module / Card

Overview
The Cisco CRS-4-FC Switch Fabric Module (also known as the CRS-4-FC Card) is a high-performance fabric component designed for the Cisco Carrier Routing System (CRS). It provides scalable, non-blocking switching capacity for large carrier and service provider networks, enabling efficient packet forwarding and robust resiliency across the core routing platform.

Key Features

• High density 40 Gbps fiber channel interfaces for ultra-fast data transport
• Non-blocking architecture that supports full line-rate traffic under peak loads
• Redundant power and cooling options for continuous operation
• Hot-swap capability allows maintenance without service interruption
• Advanced error detection and correction to ensure data integrity
• Seamless integration with existing CRS chassis and software releases
