The building drop cable is the access network from the user introduction point to the user termination point (such as the campus distribution frame, building distribution frame, etc.) or the user. A section of optical cable between optical nodes, usually drawn from outdoors and terminated indoors. At present, there are differences in the different laying methods of the incoming optical cables in buildings. structure and performance requirements. GB /Z 41287 "Introduction to Optical Cables for Communication Buildings" is divided into the following two according to the laying method of optical cables part.

1.Drop cables for pipes and direct burial. The purpose is to standardize communication buildings with pipelines and direct burial Structure and performance requirements of drop cables.

2.Self-supporting overhead drop cables. The purpose is to standardize the introduction of communication buildings with self-supporting overhead laying. The structure and performance requirements of the incoming optical cable. Building drop cables for communication Part

1 Scope

GB/Z 41287.2-2022 is the Chinese national standard on optical fibre telecommunication cables for use in premises cabling - part 2:optical fibre cables for self-supporting aerial application, in the field of telecommunications and audio-video engineering. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 9 March 2022 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. 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.
