3U Rackmount Fiber Enclosure

This 3U rackmount fiber enclosure from Black Box Corporation accepts up to 12 adapter panels or LGX cassettes. It supports a maximum of 288 fibers for high-density terminations. The unit fits both 19-inch and 23-inch rackmount fiber applications. A smoked-plastic, lockable front door protects patch cords while allowing easy viewing of connections.

Rack Compatibility and Panel Requirements

Before ordering, verify that your rack uses standard 19-inch or 23-inch mounting rails and has 3U of free vertical space. The enclosure requires fiber adapter panels or LGX cassettes to terminate fibers, which are not included. Ensure you have the correct panel types for your connector style and fiber count. Adjustable rackmount brackets are supplied for installation flexibility.

Suited for High-Density Patch Management

This enclosure suits network managers who need to organise and secure up to 288 fibers in a single 3U chassis. The lockable front door and removable rear cover provide both security and rear access for patch cords and pigtails. It is not intended for users who require pre-loaded cassettes or adapter panels included in the package. Buyers needing a smaller footprint or lower fiber capacity should consider alternative enclosures.

Questions about this item

What comes with the enclosure and do I need to buy adapter panels separately?

The unit includes adjustable rackmount brackets for 19 or 23 inch racks, a smoked-plastic lockable front door and a removable rear cover. Up to 12 fiber adapter panels or LGX cassettes must be purchased separately to reach the 288-fiber capacity.

Should I choose 19-inch or 23-inch rackmount brackets for my cabinet?

Both bracket sets are supplied and adjustable, so the same enclosure fits either a 19-inch or a 23-inch rack without needing a different model.

How many fibers can I actually terminate when the enclosure is fully populated?

With all 12 adapter panels or LGX cassettes installed, the enclosure supports up to 288 fibers for high-density patching and termination.
