T/CSTE 0108-2021 Leader Standard Evaluation Requirements for Indoor Optical Cables

Scope

Scope: This document specifies the terms and definitions, evaluation index system, evaluation methods, and grade classification for the "Leader" standard evaluation of indoor optical cables. This document is applicable to the evaluation of enterprise standards for indoor optical cables with an outer diameter not exceeding 12mm used in communication networks, communication equipment, and data centers. Relevant institutions may refer to this document when formulating evaluation schemes for enterprise standards of "Leader". Enterprises may also refer to this document when formulating enterprise standards. Main technical content: 4.2 Classification of evaluation indexes 4.2.1 The evaluation indexes for the "Leader" standard of indoor optical cables mainly include: basic indexes, core indexes, and innovative indexes; 4.2.2 Basic indexes include heat shrinkage rate, environmental performance, crushing, impact, repeated bending, twisting, flexure, coiling, bending under tension, bending, and single-rod vertical combustion. 4.2.3 Core indexes include attenuation coefficient, flame retardancy, temperature cycling, tensile strength, smoke density, and low-temperature coiling. Core indexes are divided into three grades, including advanced level, equivalent to the 5-star level in the enterprise standard ranking list; average level, equivalent to the 4-star level in the enterprise standard ranking list; and baseline level, equivalent to the 3-star level in the enterprise standard ranking list. 4.2.4 Innovative indexes include adaptability to constant humid and thermal environments and maximum core count. Innovative indexes are divided into three grades: advanced level, average level, and baseline level. Among them, advanced level is equivalent to the 5-star level in the enterprise standard ranking list; average level is equivalent to the 4-star level in the enterprise standard ranking list; and baseline level is equivalent to the 3-star level in the enterprise stand
