GB/T 4011-2013 1.2/4.4 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 1.2/4.4 mm coaxial integrated communication cables.
This standard applies to the manufacture, acceptance, and use of 1.2/4.4 mm coaxial integrated communication cables.
The cables specified in this standard are suitable for analog trunk communication systems with a frequency of up to 22 MHz or digital communication systems with a speed of up to 34 Mbit/s. High-frequency four-wire groups and high-frequency twisted-pair groups are used for analog communication systems with a frequency of up to 156 kHz, and low-frequency four-wire groups and low-frequency twisted-pair groups are used for audio communication systems.
