Left back side of the cabinet is used for optical cables entry; there is a convenient access to optical shelves with splice cassettes.

Optical cables and patchcords entry is provided both from the top and bottom. Entries are provided with special means, which allow cable or tube fixing and optical patchcords or modules distribution in protecting tubes (streamer airspeed tube – up to 6 modules per a tube). Removable panels protect cable and patchcord entries from dust penetration. In case of need the panel is removed and is replaced by special device for cable fixation and patchcords distribution.

For unification it is recommended to use noncombustible cable with up to 144 fibers with one module capacity of 12 fibers.

The cabinet sides are removable to provide further optical crosses capacity increase. When additional cabinets are installed, the cabinet sides are removed and allow optical ports switching between cabinets.

 

RP14402 shelf

RP14402 optical shelf is a 4U modular constructive with possibility to be installed into 19II track Shelf capacity is 144 optical ports. 6 or 12 modules are assembled into the shelf. Each module provides 24 or 12 optical connectors according to customer’s requirements: SC/LC/FC.

If customized, it is possible to assemble optical splitters with divisions from 1/2 to up to 1/32 into the RP-14402 optical shelf. Splitters can be compact with terminated fibers in 900 µm buffer tube. Optionally splitters can be in box design with outlets in 2-3mm diameter patchcord jacket. In this case the splitters number in box design, splitters division, and outlets length should be customized. The shelf is covered with a removable panel.
