Cisco 7600-ES+40G3CXL 7600 Series 40x 1GB SFP Line Card

The Cisco 7600-ES+40G3CXL line card is engineered to deliver high-density Gigabit Ethernet connectivity within the robust Cisco 7600 Series platform. Designed for enterprises, service providers, and large-scale network environments, this line card provides exceptional scalability, performance, and reliability. It integrates forty 1 Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports, enabling flexible optical connectivity options across a wide range of network infrastructures. With the inclusion of the Distributed Forwarding Card 3CXL (DFC-3CXL), this module enhances distributed forwarding capabilities, ensuring optimized packet processing and reduced latency.

High-Density Port Configuration for Scalable Deployments

The 40-port configuration of this line card makes it ideal for environments that demand extensive connectivity without compromising on performance. Each SFP port supports a variety of transceiver modules, allowing network administrators to tailor connectivity based on distance, bandwidth, and medium requirements. This flexibility enables seamless integration into metropolitan area networks, enterprise campus cores, and data center aggregation layers.

Flexible SFP Connectivity Options

The support for multiple SFP modules allows the Cisco 7600-ES+40G3CXL to adapt to diverse networking scenarios. Whether deploying short-range multimode fiber connections or long-range single-mode links, the module ensures consistent performance across varying environments. This adaptability significantly reduces infrastructure complexity while maximizing investment value.

Optimized Port Utilization

With forty Gigabit Ethernet ports available on a single line card, network designers can significantly reduce the number of required modules and chassis slots. This consolidation leads to improved rack space efficiency and simplified cable management, which is critical in high-density deployments.

Distributed Forwarding Card 3CXL (DFC-3CXL) Capabilities

The integration of the DFC-3CXL is one of the defining features of this line card. It provides local forwarding intelligence directly on the module, reducing dependency on the central supervisor engine. This distributed architecture enhances throughput and ensures consistent performance even under heavy network loads.

Enhanced Packet Processing Efficiency

The DFC-3CXL enables line-rate forwarding by offloading packet processing tasks from the central processor. This results in faster data transmission and improved network responsiveness. In high-traffic environments, such as service provider backbones or enterprise cores, this capability ensures uninterrupted service delivery.

Advanced Routing and Switching Features

With DFC-3CXL support, the line card is capable of handling complex routing protocols, including IPv4 and IPv6. It also supports advanced features such as multicast routing, access control lists, and quality of service mechanisms. These capabilities make it suitable for mission-critical applications that require precise traffic management.

Scalability for Growing Networks

The distributed forwarding architecture allows networks to scale horizontally without degrading performance. As additional line cards are added, each contributes its own processing power, ensuring that the overall system can handle increased traffic volumes efficiently.

Performance and Throughput Optimization

The Cisco 7600-ES+40G3CXL is designed to deliver high throughput across all ports simultaneously. Its architecture supports wire-speed performance, ensuring that data packets are transmitted without bottlenecks. This makes it particularly suitable for environments where high bandwidth utilization is critical.

Low Latency Data Transmission

Low latency is a key requirement in modern networking, especially for real-time applications such as voice over IP, video conferencing, and financial transactions. The line card minimizes latency through efficient hardware-based forwarding and optimized packet handling mechanisms.
