GB/T 4012-2013 2.6/9.5 mm composite coaxial cable for telecommunication use
Basic Information
Scope
This standard specifies the models, specifications, electrical performance, delivery length, acceptance rules, test methods, and marking and packaging of 2.6/9.5 mm coaxial integrated communication cables.
This standard applies to the manufacture, acceptance, and use of 2.6/9.5 mm coaxial integrated communication cables.
The cables specified in this standard are suitable for 24 MHz and lower analog trunk communication systems or high-speed data, image fax, television, and other digital or analog broadband information transmission communication systems. High-frequency four-wire groups and high-frequency twisted-pair groups are used for 123 kHz and lower analog communication systems. Low-frequency four-wire groups are used for audio communication systems.
