# QSFP28 Cable Assembly Overview and Applications

## Introduction to QSFP28 Cable Assembly

The QSFP28 (Quad Small Form-factor Pluggable 28) cable assembly is a high-speed interconnect solution designed for modern data centers and high-performance computing environments. This advanced cabling technology supports data rates of up to 100Gbps per port, making it an essential component in today’s bandwidth-intensive applications.

## Key Features of QSFP28 Cables

QSFP28 cable assemblies offer several distinctive features that set them apart from previous generations:

• High-density 100Gbps connectivity
• Low power consumption compared to alternative solutions
• Hot-pluggable capability for easy installation and maintenance
• Backward compatibility with QSFP+ ports
• Multiple length options from 1 meter to 100 meters

Types of QSFP28 Cable Assemblies

There are several variants of QSFP28 cable assemblies available to meet different networking requirements:

1. Direct Attach Copper (DAC) Cables

These are cost-effective solutions for short-reach applications, typically used for connections within racks or between adjacent racks.

2. Active Optical Cables (AOC)

AOCs provide longer reach than DAC cables while maintaining low latency and high reliability.

3. Breakout Cables

These cables allow a single QSFP28 port to connect to multiple lower-speed ports (such as four 25Gbps connections).

Applications of QSFP28 Cable Assemblies

QSFP28 cables find extensive use in various high-performance networking environments:

• Data Center Interconnects: Connecting servers, switches, and storage devices in modern data centers
• High-Performance Computing: Supporting cluster interconnects in scientific and research applications
• Telecommunications: Backbone connections in 5G networks and service provider infrastructures
