IEC 60728-1-1:2014

Overview

IEC 60728-1-1:2014 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies requirements for RF cabling in two-way home networks. This standard applies to networks distributing television signals, sound signals, and interactive services within the home environment. It covers wired and wireless transmission paths operating primarily between 5 MHz and 3,000 MHz, with extensions up to 6,000 MHz for wireless communication replacing wired cords.

The 2014 edition is a technical revision of the 2010 version, incorporating updated performance requirements to support modern digital broadcast technologies, including DVB-T2 signals. This standard should be used alongside IEC 60728-1:2007 for comprehensive understanding and implementation.

Key Topics

• Scope and Application: Focus on RF cabling within home two-way networks, supporting bi-directional signals primarily for TV, sound, and interactive services.
• Frequency Range: Supports 5 MHz to 3,000 MHz frequency range, extended to 6,000 MHz for wireless two-way communication technologies.
• Performance Requirements: Detailed parameters including impedance, signal level, carrier level consistency, frequency response, interference mitigation, and noise levels at system outlets and terminal inputs.
• Measurement Methods: Prescribed testing techniques for evaluating home network performance to ensure compliance with standard specifications.
• Home Network Interface (HNI): Specifications and performance criteria at different HNI points (HNI1, HNI2, HNI3) within the network setup.
• Home Network Design: Guidelines and practical examples using coaxial, balanced cables, optical fibers, and wireless links; including system outlet designs and return path configurations.
• Wireless Integration: Incorporation and coexistence of WLAN signals (IEEE 802.11) in home networks, support for 2 GHz to 6 GHz bands, and hybrid cable-wireless system configurations.
• Interference and Isolation: Strategies for minimizing intermodulation, crossmodulation, and signal interference between forward and return paths and among system outlets.
• Technical Figures and Tables: Illustrative examples of network configurations, signal levels, link budgets, isolation methods, MIMO techniques, and other essential data for practical deployment.
