Foreword

This code is revised by China Mobile Group Design Institute Co., Ltd. jointly with the

organizations concerned according to the requirements of Document JIANBIAO [2012]

No.5 issued by the Ministry of Housing and Urban-Rural Development- Notice on Printing

and Distributing 'the Development and Revision Plan of National Engineering

Construction Standards in 2012'.

During the process of formulating this code, the code drafting group carries out extensive

investigations and studies, carefully summarizes the practical experience, refers to the

relevant international and foreign standards, extensively solicits opinions and finalizes this

code through review.

This code comprises nine chapters and three annexes, with the main technical contents

including. General Provisions, Terms and Abbreviations, System Design, Fiber to the

Subscriber Unit Communication Facilities, System Configuration Design, Performance

Indicators, Installation Requirements, Electrical Protection and Grounding, Fire

Prevention, etc.

The following technical deviations have been made with respect to the former code.

(1) The design requirements of the campus and building generic cabling system and the

communication infrastructure engineering are supplemented and perfected on the basis of

the contents of GB 50311-2007 Code for Engineering Design of Generic Cabling System.

(2) The contents relevant to the application of cabling system in weak system are added.

(3) The engineering design requirements for fiber to the subscriber unit communication

facilities are added, and the mandatory provisions relevant to the engineering construction

of fiber to the subscriber unit communication facilities are newly added.

(4) The installation requirements for pipe chase and equipment are enriched.

(5) Relevant annexes are added.

In this code, the provisions printed in bold type are mandatory ones and must be enforced

strictly.

The Ministry of Housing and Urban-Rural Development the People's Republic of China is

in charge of the administration of this code and the explanation of the mandatory

1 General Provisions

1.0.1 This code is formulated with view to standardizing the construction of network

integrating voice, data, picture and multimedia services for buildings and campus.

1.0.2 This code is applicable to the engineering design of generic cabling system for

constructed, extended and renovated buildings and campus.

1.0.3 The construction of facilities in generic cabling system shall be included in the

corresponding planning and design of buildings and campus. The design shall be carried

out according to the nature, functions and environmental conditions of engineering project

and the short-/long-term subscriber demands, and the construction and maintenance

convenience shall be taken into consideration to ensure the quality and safety of generic

cabling system engineering and to achieve advanced technology and economic

rationality.

1.0.4 Generic cabling system should be planned as a whole and also be designed
