Fiber optic wall indoor box EFB Elektronik FTTH for 4x SC simplex / LC duplex, IP20

The EFB Elektronik FTTH fiber optic wall indoor box is a compact enclosure designed to provide a tidy termination and distribution point for indoor fiber installations. Intended for mounting on walls, the unit accommodates up to four SC simplex or LC duplex connectors and includes space for fiber routing and splice protection. Its IP20 rating makes it suitable for protected indoor environments in residential and small commercial FTTH deployments, offering organized connector access and simplified maintenance.

Advantages

The enclosure provides organized housing for multiple fiber connectors while protecting terminations from accidental contact. Its compact form factor and clear internal layout allow for straightforward installation and cable management. The design supports both SC simplex and LC duplex connector types, enabling flexibility in connector use and network planning. The IP20 protection class ensures the unit is appropriate for indoor use where dust and contact risks are limited.

How to use

Mount the box on a clean, dry interior wall at a convenient height and route incoming and outgoing fiber cables into the enclosure through the designated cable entries. Secure fibers in the routing channels and manage excess fiber length according to bend-radius guidelines to avoid signal loss. Install connectors or fusion splices in the provided splice area and secure them following standard optical fiber termination practices. Close the cover to protect terminations and maintain organized access for future maintenance.

Usage recommendations

Use appropriate cable strain relief and maintain minimum bend radii for single-mode or multimode fibers. Perform connections and splicing in a dust-free environment and use dust caps on unused adapters. Reserve the enclosure for indoor, protected locations consistent with the IP20 rating and avoid exposure to moisture or harsh contaminants.
