The FTTx Solution® SlimBox™ Drop System – Where Simplicity and Versatility Meet to Provide a Smarter FTTH Connection

The SlimBox Underground Terminal is used to connect distribution cables in the outside plant network to drop cables in FTTx networks, including Fiber to the Home, Building, or Cell Site. It enables quick and easy connections through plug and play connectorized drop cables, fusion splicing, splice on connectors, or mechanical connectors.

It has one area for storage and splicing, and a separate area for management and activation of subscribers. The mechanical sealing system supports round drop cables, making the terminal ideal for both underground and aerial applications.

The SlimBox Underground Terminal can be configured to support a variety of needs: fusion splices (up to 4 splice trays, with 16 splice protectors holder each), spliced and connectorized drops (up to 2 splice trays and 1 adapter tray with up to 16 SC adapters). In addition it can house up to 2 factory connectorized 1x8 splitters, or 1 factory connectorized 1x16 splitter. It can also house unconnectorized splitters.

The terminal accepts entry cables with a maximum diameter of 17.5 mm. It is possible to implement mid-span branching of the main cable using the oval ports, whereas the network branching can be implemented using the round ports. It is compatible with round (2 to 4 mm) drop cables.

The terminal also has wall, pole and steel wire mounting supports, besides being suitable for underground installation.
