This subrack is typically used in Optical Fibre Termination Frames, or Customer cabinets, to provide a reliable, low loss permanent connection between optical fibre cables for DWDM or similar systems.
The main functions of the subrack are to provide: a managed standard fibre installation, reticulation, interconnection and distribution activities at a common point. It also allows for fibre testing and fault finding activities.
A major feature of this subrack is the minimum amount of movement that occurs to loose tubes (and optical fibre cords), as the tray opens and closes. This ensures a very high degree of protection for working services. Also, the fusion splices are located in a protected position, because there is very little chance of them being disturbed when the subracks tray is opened.
