1 Scope This standard specifies communication cables - coaxial/twisted pair hybrid cables The product classification, requirements, test methods, inspection rules, packaging and packaging markings, transportation, and storage of cables (hereinafter referred to as cables). The products specified in this standard are mainly used to connect telephone/multimedia lines from wiring terminals to network interface devices or network interface units or users. Coaxial cable units are used to transmit video, analog signals, and compressed digital signals, as well as high-speed digital signals. The work of coaxial cable units The frequency range is 5-1000MHz; Twisted pair units are typically used for transmitting audio, analog signals up to 150kHz, and digital signals up to 2048kbit/s. Under certain conditions, their maximum operating frequency can reach 6.3MHz. 2. The clauses in the following documents are referred to in this standard and become the clauses of this standard. For dated documents, all subsequent amendments (excluding corrected content) or revisions are not applicable to this standard. However, parties to agreements based on this standard are encouraged to study whether to use the latest versions of these documents. For undated references, the latest version applies to this standard.
