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 an external optical fibre cable is fusion spliced to pigtails, which are connected to patch cords. Typically the patch cords can cross-connect (in an FTF) or connect to transmission equipment.
A major feature of this tray 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 and pigtails are located in a protected position, because there is very little chance of them being disturbed when patch cords are being installed, as the subracks tray only needs to be opened a very small amount.
Splice/Patch RH pivot open Subrack (2RU), for 72 multimode OM3 optical fibres, rear mounts in a 19“ rack
Maintains fibre bending radii throughout, for optical fibres at 30mm.
Supplied with 1 set of 6 high 12 fibre, splice tray assemblies (Part No: TC251S-6AX), for 72 fusion splices.
Two splice protector holder clips located on each splice tray.
Splicing aided by using the splice tray holding bracket, to hold open splice tray stack
Optical fibre tubes are fed to the trays LHS entry securing point, then around the rear of the body under a guiding/protection plate, to pass around the RHS guiding cylinder to the splice trays, through smooth, large curves.
Cable is secured at LHS entry point
