Overview
This Technical Specification specifies the processes to be employed for the repair of damage to installed optical fibre cabling by reinstatement of the outer sheath or the replacement of an optical fibre cable between existing closures with the objective of restoring its pre-damaged performance and in order to maintain pathway capacity. Interim repair procedures, including temporary and/or partial repairs including the introduction of additional joints of connections, which deliver the minimum functionality to meet immediate performance requirements, are also described. The repair processes specified are applicable to all installation environments except optical ground wires (OPGW) or optical phase conductors (OPPC). The responsible committee is DKE/UK 412.6 "Lichtwellenleiter und Lichtwellenkabel" ("Optical fibres and fibre cables") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
