9、ized agency in the field of telecommunications, information and communication technologies (ICTs). The 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 wit

10、h a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization 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 Reco

11、mmendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this publication, the expression “Administration“ is used for conc

12、iseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this publication is voluntary. However, the publication may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the publication is

The use of such words does not suggest that compliance with the publication is required of any party. INTELLECTUA

24、dations Optical fibre and cable Recommendations and standards guideline 1 Scope This fibre guideline aims at providing a road map with regard to the specifications of various kinds of fibres and their test methods, as well as the most important fibre optics hardware which will be very useful for eng

25、ineers reading the ITU-T Recommendations and other documents to design an optical fibre network. This guideline should also make it easier for readers to correlate the specifications found in the fibre, terrestrial system interface, components, submarine systems and physical infrastructure Recommend

26、ations currently being developed in ITU-T. Moreover, this guideline provides important information for system designs and optical fibre cable installations in relation to, for example, high power limitations and reliability, which is available to optical fibre cable installation suppliers and system

27、 designers. This guideline contains: Definitions of fibre parameters not specified in current ITU-T fibre Recommendations but which are very important for practical use. Features of existing optical fibre categories and their application areas. The relationship between fibre parameters and interface

28、 parameters. Optical fibre properties for operation and maintenance. In the appendices, the following items are described for reference: Standardization criteria for optical fibres in ITU-T Study Group 15. Optical fibre cable structures and constructions. Fibre optics hardware and passive components

29、 mostly used in the construction of an optical network. Comparison of ITU-T Recommendations and IEC documents related to optical fibre specifications and test methods. In particular, this guideline is prepared concisely by quoting document numbers so as to avoid any overlap with existing ITU-T Recom

30、mendations and Handbooks or IEC documents. This guideline would be a very useful desk book for engineers dealing with optical transmission systems. 2 References ITU-T G.650.1 Recommendation ITU-T G.650.1 (2004), Definitions and test methods for linear, deterministic attributes of single-mode fibre a
