Chamber Distribution Box

The Chamber Distribution Box is a fibre optic closure for splicing and distributing fibre cables, primarily in underground networks. It provides six round in/out cable ports that accept cables between 8mm and 20mm in diameter, giving flexibility to route feeder and distribution cables through a single enclosure. Inside, splice trays with a capacity of 24 fibres keep spliced fibres organised and protected, making the box well suited to distribution points where a feeder cable is broken out towards customers. Manufactured from high-quality thermoplastic with high mechanical strength, the enclosure is designed to withstand the conditions found in underground chambers and footway boxes. An integrated seal keeps it airtight and waterproof, protecting against water, dirt and dust ingress that can degrade splices over time. For FTTx and telecom network builders, the Chamber Distribution Box offers a robust, practical way to create underground splice and distribution points that are easy to access for future maintenance and network expansion.

Applications

Underground distribution points: splicing and breaking out feeder cables in chambers and footway boxes on FTTx networks.

Network extension: creating new splice points when extending an existing underground fibre route to additional streets or premises.

Splice protection: housing up to 24 spliced fibres in a sealed, waterproof enclosure where water and dust ingress are a risk.
