Main Distribution Frame (MDF) Product Introduction
1. Product Overview
The Main Distribution Frame (MDF) is the core patching equipment in communication networks, designed for centralized connection, cross-connection, and protection between external cables and internal devices. As critical infrastructure in equipment rooms, base stations, and data centers, MDF provides high-density, modular patching solutions to ensure efficient transmission and flexible management of voice, data, and other communication signals.
Key Functions:
✔ Cable termination and cross-connection management
✔ Overvoltage/overcurrent protection (optional lightning protection module)
✔ Line testing and fault localization
✔ Supports hybrid deployment of copper cables (voice/data) and fiber optics
2. Product Advantages
✅ High-Density Design, Space-Saving
Supports configurations of 256/512/1024 lines and higher capacities
Modular terminal blocks, with each module supporting 25/32 lines for easy expansion
✅ Secure & Reliable, Intelligent Protection
Three-level protection (primary/secondary/tertiary lightning protection), compliant with ITU-T K.20/K.21 standards
Optional intelligent monitoring module (real-time monitoring of line status, current, and voltage)
✅ Flexible Adaptation, Efficient O&M
Dual-sided (front/rear) operation for easier jumper management
Color-coded labeling system for quick route identification
✅ Industrial-Grade Durability
Terminal blocks: Phosphor bronze gold-plated, with ≥200 insertion/extraction cycles
