I n t rod u ct i o n The present document covers mechanical splices for single mode optical fibres and cables.

12、The optical fibres are those described in EN 188100 9 (sectional specification) and EN 188101 101 (family specification). 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 splice

13、s. The considered splices are between single fibres, between ribbon 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

14、obtain the required functional behaviour of mechanical splices it is necessary to follow a number of procedures for fibre preparation, fibre alignment, jointing and protection as described in FU-T Recommendation L. 12 8. All the following requirements are referred to protected splices measured in la

The scope covers the establi

16、shment of minimum uniform requirements for the following aspects: - - test conditions; optical, environmental and mechanical properties; - acceptance criteria. Some users may have additional specific requirements, such as a need to verify performance at lower temperatures. These users should specify

17、 mechanical splices conforming to the basic ETSI 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 R
