Introduction

GB/T 18233 "General Cabling for Information Technology User Buildings" is intended to guide the design of general cabling systems in specific types of buildings.

GB/T 18233 is compiled based on ISO/IEC 11801.According to ISO/IEC 11801, according to different building types and scenes, GB/T 18233 is planned to consist of 6 parts.

--- Part 1: General requirements. The purpose is to provide a design basis for a general cabling system for user buildings and to provide a design basis for a cabling system for a specific location.

Provides a general reference for system design.

--- Part 2: Office space. The purpose is to provide a design basis for general cabling systems in office spaces.

--- Part 3: Industrial buildings. The purpose is to provide a design basis for a general cabling system for industrial buildings.

--- Part 4: Residential. The purpose is to provide a design basis for common residential cabling systems.

--- Part 5: Data Center. The purpose is to provide a design basis for a general cabling system for a data center.

--- Part 6: Distributed building facilities. The purpose is to provide a design basis for a common cabling system for distributed building facilities.

This document specifies requirements for general cabling within a residence. A residence may consist of one or more buildings (e.g. a farm), or be located in an area containing in buildings with multiple residences (e.g., a residence in a multi-family building).

According to relevant standards, such as GB/T 18233.1-2022 or IEC 60728 (all parts).

General cabling is specified in GB/T 18233.6.

Information technology cabling standards developed by ISO/IEC JTC1/SC25 and translated into Chinese the overview and context of the standards include universal cabling design standards, universal cabling installation, operation and management standards, and installed universal cabling testing standards.

This document.

a) Specifies a general cabling structure that supports multiple applications, including but not limited to the applications in Appendix A of GB/T 18233.1-2022;

b) Uses Class D, Class E, Class EA, Class F, Class FA and Class BCT-B balanced cabling as specified in GB/T 18233.1-2022 link;

c) BCT-C coaxial cable channels and links specified in GB/T 18233.1-2022 are used;

d) The component requirements specified in GB/T 18233.1-2022 are adopted, and the requirements for ensuring that permanent link and channel performance meet or exceed Deployment methods that are required by specific application groups (such as levels).

The life expectancy of a general cabling system depends on the environmental conditions, the application being supported, the material of the cable, and other factors such as the length of the path.

Access (campus paths are more difficult to access than building paths). By selecting appropriate components, the expected life of the general cabling system that meets the requirements of this document can be Life span is more than 10 years.
