1. Overview

Modular cables are standardized, customizable cable assemblies designed for flexible connectivity in electronic systems. Their plug-and-play architecture enables rapid deployment, scalability, and maintenance efficiency. These cables serve as critical infrastructure in data centers, industrial automation, and telecommunications, supporting seamless integration of hardware components while maintaining signal integrity and power delivery.

2. Main Types and Functional Classification

3. Structural Composition

Typical modular cables feature:

• Conductive Core: Annealed copper (20-24 AWG) with oxygen-free purity ( 99.95%)
• Insulation: Cross-linked polyethylene (XLPE) or fluorinated ethylene propylene (FEP)
• Shielding: Braided aluminum/mylar layers with 95%+ coverage
• Connectors: Hot-swappable RJ45/USB-C/M12 interfaces with 500+ mating cycles
• Strain Relief: Thermoplastic elastomer (TPE) boots for 20N+ tensile strength
