IEC 60728-106:2023

Overview

IEC 60728-106:2023 is an international standard developed by the International Electrotechnical Commission (IEC) that addresses the optical equipment used in cable networks for television signals, sound signals, and interactive services where the systems are loaded with digital channels only. This standard provides a comprehensive framework for the measuring methods, performance requirements, and data publication requirements of optical devices utilized in modern digital cable networks. It is applicable to a wide range of equipment, including optical transmitters, receivers, amplifiers, directional couplers, isolators, multiplexing devices, connectors, and splices. The standard specifically covers systems operating in the frequency range of 5 MHz to 3,300 MHz.

Adoption of IEC 60728-106:2023 supports international harmonization in cable network design and maintenance, ensuring minimum performance levels and facilitating product quality, interoperability, and compliance testing.
