Brand:

Arista

Specifications

Product Overview:

The Arista CAB-Q-4S-100G-3M is a high-performance 3-meter direct attach breakout cable engineered to bridge QSFP and SFP28 interfaces seamlessly. Designed for short-distance, high-speed connectivity, this cable supports an aggregate bandwidth of 100Gbps, split across four independent 25Gbps SFP28 links.
Ideal for modern data centers and cloud infrastructures, this breakout cable facilitates efficient network architecture by enabling one high-capacity QSFP port to connect multiple lower-speed SFP28 devices, optimizing switch port usage and reducing cabling complexity.
Its durable build and compact design ensure reliable signal integrity and easy routing within dense rack environments. The cable is hot-pluggable and compatible with standard QSFP and SFP28 ports, making deployment straightforward.

Key Features:

100Gbps Total Bandwidth – Supports 4 lanes of 25Gbps each via breakout connections.
3-Meter Length – Perfect for rack-level and short-range connections in data centers.
QSFP to 4x SFP28 – Converts a single QSFP port into four separate 25Gbps links.
Direct Attach Breakout Cable (DAC) – Low latency, low power, and cost-effective cabling solution.
Compact and Flexible – Simplifies cable management in high-density environments.
Plug-and-Play – Hot-swappable design with broad compatibility across networking gear.

Technical Specifications:

Cable Type: Direct Attach Breakout Cable (DAC)
Model Number: CAB-Q-4S-100G-3M
Cable Length: 3 meters
Connector 1: QSFP (CR4 interface)
Connector 2: 4 x SFP28 (25Gbps each)
Data Rate: 100Gbps aggregate (4x 25Gbps lanes)
Applications: Data Centers, Cloud Networking, Enterprise

Use Cases:

Breaking out a 100G QSFP port to multiple 25G SFP28 switch or server ports.
High-density rack cabling for top-of-rack (ToR) and leaf-spine network designs.
Cloud and hyperscale data center environments requiring flexible bandwidth aggregation.
Efficiently connecting storage arrays, servers, and switches with mixed interface speeds.

Benefits:

Maximizes port utilization by splitting a single 100G link into four 25G channels.
Reduces cable clutter and cost compared to deploying multiple separate cables.
Simplifies network upgrades with backward-compatible breakout support.
Ensures reliable high-speed connectivity with low latency and power consumption.
