ITU-T L.103 (04/2016) i Recommendation ITU-T L.103 Optical fibre cables for indoor applications Summary Recommendation ITU-T L.103 (formerly, L.59) describes characteristics, construction and test methods for optical fibre cables for indoor applications.

6、 In order for an optical fibre to perform appropriately, characteristics that a cable should have are described. Also, the method of determining whether the cable has the required characteristics is described. Required conditions may differ according to the installation environment; detailed test co

7、nditions need to be agreed upon between the user and manufacturer for the environment where a cable is to be used.

ITU-T L.103 (04/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The

10、 ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standar

11、dization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information t

12、echnology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Comp

13、liance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other o

14、bligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementa

15、tion of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As

16、of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged

24、ecifies the mechanical and environmental characteristics of the optical fibre cables concerned. The optical fibre dimensional and transmission characteristics, together with their test methods, should comply with one or more of ITU-T G.651.1, ITU-T G.652, ITU-T G.653, ITU-T G.654, ITU-T G.655, ITU-T

25、 G.656, ITU-T G.657 and IEC 60793-2-10; Specifies the fundamental considerations related to optical fibre cable from mechanical and environmental aspects; NOTE Other types of fibre may be used to meet the intent of cables according to this Recommendation. Specific attributes may differ, and require

26、agreement between the manufacturer and user. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
