Brand:

Arista

Specifications

Product Overview

The Arista CAB-Q-4S-100G-1M is a high-performance, 1-meter breakout cable designed for short-reach, high-speed data interconnects in modern data center and enterprise networking environments. With its QSFP+ to 4x SFP+ configuration, this cable splits a 40Gbps QSFP+ port into four independent 10Gbps SFP+ channels, delivering exceptional throughput and performance consistency.
This Direct Attach Copper (DAC) cable offers a cost-effective, energy-efficient alternative to optical transceivers for rack-to-rack and switch-to-server links.

Technical Specifications

Cable Type: Twinax Direct Attach Copper (DAC), Passive
Breakout Configuration: QSFP28 (100G) to 4 x SFP28 (25G)
Connector 1: QSFP28 (100GBASE-CR4)
Connector 2: 4 x SFP28 (25GbE)
Bandwidth Support: Up to 100 Gbps total (4 x 25 Gbps)
Length: 1 Meter (3.28 Feet)
Compatibility: Arista and industry-standard equipment supporting QSFP28 and SFP28 ports
Application Use Cases: Top-of-Rack connections, Switch-to-Server links, High-speed cluster interconnects

Key Features

Plug-and-play integration for Arista network switches and compatible gear
Ideal for short-reach connections up to 1 meter in high-speed data centers
Reduces latency and power consumption compared to optical alternatives
Rugged Twinax design for consistent signal integrity
Cost-effective high-bandwidth breakout solution

Compatibility & Use

The CAB-Q-4S-100G-1M is optimized for Arista 100GbE switches, but it’s also interoperable with many other systems supporting QSFP28 to SFP28 breakout configurations. Use this cable for:
Breaking out 100G ports into multiple 25G lanes
Server uplinks in virtualized environments
Direct connections between network elements in high-density deployments
