Specifications

Product Overview

The Arista DCS-7500R2-36CQ-LC is a high-performance 36-port 100 Gigabit Ethernet QSFP100 line card purpose-built for Arista 7500R Series modular switches. Designed to meet the demands of next-generation data centers, enterprise backbones, and cloud-scale networks, this module enables scalable high-throughput networking with wire-speed performance across all ports.
Supporting both QSFP100 and QSFP28 transceivers, it ensures flexibility in deployment and supports a wide range of connectivity options, including 100G, 2x50G, and 4x25G configurations. The card is ideal for dense core, spine, and interconnect architectures, where ultra-low latency and power efficiency are critical.
Built with reliability in mind, this line card delivers consistent performance for mission-critical workloads and ensures non-blocking throughput across all 36 ports.

Key Features

36 x 100GbE QSFP100 Ports – Delivers exceptional port density for high-bandwidth aggregation and core deployments.
Wire-Speed Throughput – Each port supports full 100 Gbps without compromise on latency or performance.
Low Latency Architecture – Ideal for high-performance environments like AI/ML, financial services, and large-scale web infrastructure.
Flexible Optics Support – Compatible with QSFP100 and QSFP28 modules including SR4, LR4, CWDM4, DACs, and AOCs.
7500R Series Compatibility – Seamlessly integrates with all Arista 7500R modular chassis.
Energy-Efficient Components – Designed to minimize power draw without compromising reliability or throughput.
Field-Replaceable Line Card – Simplifies upgrades and maintenance with hot-swappable functionality.
Robust Design for High Availability – Built to operate reliably in continuous-use environments.
