fixtures or materials, rather than by thermal fusion Note to entry: Index matching material may be applied between the two fibre ends General description Three test procedures are described Procedure A tests the ability of optical mechanical splices to be re-installed after disassembly Procedure B tests the ability to re-enter fibre management systems and closures, by accessing fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits Procedure C verifies the sealing performance after frequent opening and closing of enclosures The mechanical splice, fibre management system or (en)closure shall be assembled and reassembled a specified number of times following the manufacturer's instructions, including any specified cleaning or recovery procedure The test shall be done according to requirements referenced in IEC 61753-1 Assembly and disassembly of the mechanical splice, fibre management system or closure shall be carried out at room temperature, unless otherwise specified Procedure 5.1 Preparation of the specimen Assembly tools and consumable materials, as specified by the manufacturer, shall be used 5.2 Test procedures 5.2.1 Procedure A: Re-installation of an optical mechanical splice after disassembly General description of the steps for Procedure A is defined as follows 1) Assemble the mechanical splice according to the manufacturer's installation instructions using the specified fibre or cable 2) Perform any required examination and measurements as specified in the relevant performance standard 3) Perform the temperature ageing cycle as specified in the relevant performance standard When not specified, the ageing cycle as defined in Table shall be used After the ageing cycle allow the specimen to recover at ambient temperature for at least hours 4) Disassemble the mechanical splice to the specified extent or to the point that all internal fibres and devices can be accessed or removed 5) Perform any specified cleaning and fibre preparation operations 6) Re-install the mechanical splice according to the manufacturer's instructions 7) Perform any required examinations and measurements as specified in the relevant specification 8) Repeat steps through for the number of cycles specified 5.2.2 Procedure B: Optical stability during product reconfiguration General description of the steps for Procedure B is defined as follows BS EN 61300-2-33:2012 61300-2-33 © IEC:2012(E) –7– 1) Assemble the (en)closure or fibre management system according to the manufacturer's instructions using the specified fibre or cable An optical circuit is built as specified in the performance standard 2) Perform any required examination and measurements as specified in the relevant performance standard The change in attenuation in the optical circuit shall be measured with the transient loss procedure, IEC 61300-3-28, when performing steps 3, and 3) The handling operations shall be performed as specified in the performance standard (see Annex A for a typical example) The (en)closure shall be disassembled to the specified extent or to the point that the internal fibres and devices can be accessed or removed 4) Perform the specified reconfiguration operations 5) Close and secure the fibre management system and reassemble the (en)closure according to the manufacturer's instructions 5.2.3 Procedure C: Sealing performance after frequent opening and closing of the enclosures General description of the steps for Procedure C is defined as follows 1) Assemble the (en)closure according to the manufacturer's installation instructions using the specified fibre or cable 2) Perform any required examination and check sealing performance as specified in the relevant performance standard 3) When specified in the performance standard, perform the specified temperature ageing cycle After the ageing cycle, allow the (en)closure to recover at ambient temperature for at least hours 4) Disassemble the (en)closure to the specified extent or to the point that all internal fibres and devices can be accessed or removed 5) Re-install the (en)closure according to the manufacturer's installation instructions 6) Perform any required examinations and check sealing performance as specified in the relevant specification 7) Repeat steps through for the number of cycles specified 5.2.4 Ageing procedure If specified in the relevant performance standard, the product shall be submitted to an aeging process between assembly and disassembly operations The major reason for the ageing process is to speed up the creep of the polymeric materials in the alignment area or sealing area after a re-entry is completed The purpose of the ageing procedure includes: – identification of the design failures; – identification of manufacturing defects; – impact of product ageing on assembly and disassembly Table shows ageing conditions The ageing conditions are based on the operating environmental conditions given in IEC 61753-1 BS EN 61300-2-33:2012 61300-2-33 © IEC:2012(E) –8– Table – Ageing procedure between two cycles of assembly and disassembly of fibre optic mechanical

procedure for closure – optical stability When installed in the network, a fibre optic closure may be subjected to a number of manipulations related to interventions for network repair or maintenance It is important to note that after any repair or maintenance is carried out, closure operation should be restored and reset for optical transmission as it was originally specified This annex describes how to simulate the effect of these manipulations for the evaluation of the suitability of the closure This optical evaluation is carried out at room temperature, without any ageing cycle Before, during and after the manipulations, the change in attenuation in the existing optical circuits shall be measured with the transient loss procedure, IEC 61300-3-28: a) closure and cable handling: – removing a closure from its installed location to an appropriate working location; – handling of a cable that is attached to a closure b) re-entry/access after initial installation: – opening and closing of drawers and doors, or removing and reinstalling the cover of a closure; – gaining access to previously installed fibres in a fibre management system c) adding cables: – terminating and connecting additional cables; – routing the fibres to the required position and connecting them d) internal reconfiguration of connections and fibres: – breaking a splice and connecting to another fibre end; – disconnecting a connector and mating with another connector; – cutting one or more uncut fibres and connecting to another fibre end; – adding subsequent elements/devices of the fibre management system and connecting the fibres BS EN 61300-2-33:2012 61300-2-33 © IEC:2012(E) – 11 – Bibliography IEC 61300-1, Fibre optic interconnecting devices and passive components – Basic test and
