14、he present document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is a revision of I-ETS 300 783. ETSI ETSI TS 100 783 V1.2.1 (2004-08) 5 1 Scope The present document specifies requirements for fusio

15、n splices to be used in single mode optical fibre telecommunications land-based (not submarine) systems. The scope covers the establishment of minimum uniform requirements for the following aspects: - optical, environmental and mechanical properties; - test conditions; - acceptance criteria. The spl

16、ices are considered to be between single fibres, between ribbon fibres and between ribbon and multiple fibres. The optical fibres which are spliced are intended to conform to IEC 60793-2-50 4. These requirements cover splices with the same single mode fibre type. In order to obtain the required func

17、tional behaviour of the fusion splices, it is necessary to follow a number of procedures for fibre preparation, fibre alignment, jointing and protection as described in ITU-T Recommendation L.12 3. All the following requirements refer to protected splices measured in a laboratory. This ES is intende

18、d to provide criteria for the assessment of splicing equipment and techniques, including the splice protector. Some users may have additional specific requirements, such as the need to verify performance at lower temperatures. These users should specify splices conforming to the basic ETSI performan

19、ce standard plus the additional tests or more severe test conditions. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.
