T/GDWCA 0073-2020 "Leader standard evaluation requirements for communication network cables"

Scope

Scope: This document specifies the terms and definitions, evaluation index system, and evaluation methods for the "Leader" standard of communication network cables. This document applies to digital communication cables used for wiring between the communication outlet in the work area and the distribution frame in building communication integrated wiring systems, as well as cables used for wiring between the user's communication outlet and the distribution frame in integrated wiring systems. Relevant organizations can refer to it when formulating "Leader" evaluation schemes for corporate standards, and enterprises can also use it as a reference when developing their own corporate standards. Main technical content: 1. The indicators included in the "Leader" standard for communication network cables are divided into basic indicators, core indicators, and innovative indicators. 2. Basic indicators include the relevant requirements covered by mandatory standards. 3. The core indicators for communication network cables include maximum transmission frequency, flame retardancy, and delay difference. 4. The core indicators are divided into three levels: advanced level, equivalent to a 5-star level on the corporate standard ranking list; average level, equivalent to a 4-star level on the corporate standard ranking list; and baseline level, equivalent to a 3-star level on the corporate standard ranking list. 5. The innovative indicators for communication network cables include environmental protection requirements, cold bending, and anti-cracking tests. It is encouraged to add relevant innovative indicators related to product performance and consumer concerns as conditions permit.
