19” High Density Front Patching/Splicing Shelf

1. General Product Description

Designed for fiber management in a rack environment, the FOMS-FPS-HD is a high density multi-purpose mechanical shelf with front patching and optional
single element splicing. The compact design makes it possible to handle a large amount of fibers in a small footprint. FOMS-FPS-HD delivers carrier-class
fiber management to central offices and points-of-presence, as well as FTTH, mobile and local area networks.
Two versions are available

  • Patching only
  • Splicing and patching to terminate loose tube, central core, IFC (intrafacility cable) and break-out cables.

3. Shelf Description

Chassis and pivoting bottom plate

The FOMS-FPS-HD chassis are ready to be fitted inside an optical rack using mounting brackets, screws and cage nuts. The chassis width is designed
according to the 19″ standard. Adaptation brackets to ETSI are available as an option.
All chassis are painted (color RAL 7035).

Cable termination kit

A strength member fixation and cable entrance kit are included in the standard shelf to terminate loose tube single fiber or intra-facility cable.

Shelf roof

The roof of the shelf can easily be removed to facilitate internal access before the shelf is installed in a rack.

Mounting brackets

The shelf has field-mountable brackets to accommodate for:

  • back-mounting specifically for CommScope’s FIST racks
  • 2 other different back mounting positions
  • 3 different front mounting positions (see installation instructions)

A small tool (Allen key 2.5mm) is included to fix the brackets on the shelf.

Front patch panel

The patching module plane is right or left angle oriented to reduce the risk of eye damage when working with active fiber. This also prevents the outgoing
patch cords from making strong bends when leaving the shelf.

Patching-only configuration

1HU
Patch cords enter the shelf on the side and are guided towards the back of the patch panel via overlength storage basket which controls the bend radius. Patch cords connected at the front of the patch panel leave the shelf in a controlled way via the integrated bend control and the wrap-around trumpet. Adaptors are typically pre-mounted.
Caution: The 1HU patch/patch shelf doesn’t support front pigtail entrance (not enough space to install a pigtail bridge)
2HU
Patch cords enter the shelf via the front, the side or the back and are guided towards the back of the patch panel via overlength storage basket that
controls the bend radius. Patch cords connected at the front of the patch panel leave the shelf in a controlled way via the integrated bend control and the
wrap-around trumpet.
Adaptors are typically pre-mounted.

Splicing and patching configuration

Loose tube or intra-facility cables (IFC) enter via the side or back of the shelf and are guided towards the splicing trays. In case of a loose tube cable and a non pre-connectorized IFC, fibers have to be spliced to secondary coated pigtails in the splicing trays and then guided towards the back of the patch panel. In case of a pre-connectorized IFC, overlength is stored in a basket.
Patch cords connected at the front of the patch panel leave the shelf in a controlled way via the integrated bend control and the wrap-around trumpet. Secondary coated pigtails are typically pre-installed in the shelf. The tray tower can be pivoted to improve accessibility for splicing.
