This subrack is typically used in Optical Fibre Termination Frames.
The main functions of the subrack are to provide: a managed standard fibre installation, reticulation, interconnection, distribution, re-arrangement and maintenance activities at a common point. It also allows for fibre testing and fault finding activities. Typically the patch cords can cross-connect (in a FTF) or connect to transmission equipment.
A major feature of this tray is the minimum amount of movement that occurs to optical fibre cords, as the tray opens and closes. This ensures a very high degree of protection for working services. Also, the rear patch cords are located in a protected position, because there is very little chance of them being disturbed when front patch cords are being installed, as the subracks tray only needs to be opened a very small amount.
