13、resent document. Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is a revision of ES 201 263 4. Introduction The present document covers mechanical splices for single mode optical fibres and cables. The

14、 optical fibres are those described in IEC 60793-2-50 3. To minimize reflection loss caused by an air gap between the fibre ends, index-matching material can be used. Mechanical splices can be used both as temporary or permanent splices. The considered splices are between single fibres, between ribb

15、on fibres and between ribbon and multiple single fibres. Mechanical splices are field-mountable passive optical components; therefore they will be assembled by users. The manufacturer should give instructions for assembly. In order to obtain the required functional behaviour of mechanical splices it

16、 is necessary to follow a number of procedures for fibre preparation, fibre alignment, jointing and protection as described in ITU-T Recommendation L.12 2. All the following requirements are referred to protected splices measured in laboratory. ETSI ETSI TS 101 263 V1.2.1 (2004-07) 5 1 Scope The pre

17、sent document specifies requirements for mechanical splices to be used in single-mode optical fibre telecommunication land based (not submarine) systems. The scope covers the establishment of minimum uniform requirements for the following aspects: optical, environmental and mechanical properties; te

18、st conditions; acceptance criteria. Reliability aspects of connector sets are not covered by the present document. Some users may have additional specific requirements, such as a need to verify performance at lower temperatures. These users should specify mechanical splices conforming to the basic E

19、TSI performance standard, plus additional tests or more severe test conditions. Two grades of mechanical splices have been established in the present document regarding their performance in environmental tests. These are referred to as grades V and T. 2 References The following documents contain pro

20、visions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply.
