GB/T 18899-2023All dielectric self-supporting optical fibre cable (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting: This document replaces GB/T 18899-2002 "Full Dielectric Self-supporting Optical Cable": Compared with GB/T 18899-2002, except for structural adjustment and Apart from editorial changes, the main technical changes are as follows:

a) The structural type composition of ADSS has been changed (see Figure 1 in 5:2, Figure 1 in 4:2 of the:2002 edition);

b) The code of the application scenario of the optical cable is added (see 5:2:3);

c) The index requirements for optical fiber ribbons have been added (see 6:1:3:2);

d) The requirements for the inner sheath are added, especially the requirements for the thickness of the inner sheath of optical cables with a span greater than 800m (see 6:1:11);

e) Deleted multimode fiber and its index requirements (see 6:4:1, 8:1:2 of the:2002 edition);

f) The requirements for fiber attenuation index after cabling are added (see 6:4:1:3);

g) Changed the requirements for the breaking force index of the optical cable (see Table 5 in 6:4:3:2, Table 4 in 8:3:2 of the:2002 edition);

h) Changed the classification requirements for decay temperature characteristics (see Table 7 in 6:4:4:2, Table 6 in 8:4:2 of the:2002 edition);

i) The test method for combustion performance has been changed (see 6:4:4:6, 9:6:6 of the:2002 edition);

j) Added requirements and test methods for outer sheath wear and loose tube bending (see 7:3:1);

k) Changed the acceptance requirements for the impact test (see 7:5:5, 8:3:4 of the:2002 edition);

l) Changed the acceptance requirements for repeated bending tests (see 7:5:6, 8:3:5 of the:2002 edition);

m) Added the bending test under tension (see 7:5:11);

1 Scope

GB/T 18899-2023 is the Chinese national standard on all dielectric self-supporting optical fibre cable, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 23 May 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2023. Classification: ICS 33.180.10, CCS M33. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the model, designation, requirements, test methods, and inspection of all-dielectric self-supporting optical cables (ADSS optical cables, hereinafter referred to as optical cables): Regulations, packaging, transport and storage: This document is applicable to the design, development, production and testing of ADSS optical cables for communication lines used in overhead power transmission systems, and is also applicable to lightning-prone ADSS optical cables in aerial laying environments such as strips and large spans:
