Fiber optic wall indoor box EFB Elektronik FTTH FTth-box-in-2 for 2x SC simplex / LC duplex, IP20

Indoor FTTH wall box by EFB Elektronik designed for subscriber fiber terminations and neat cable routing in apartments, small offices and other indoor environments. The Ftth-box-in-2 accepts up to two SC simplex connectors or one LC duplex connector and provides integrated fiber management and connector protection in an IP20-rated housing. The compact design allows flush or surface mounting on standard walls and offers a tidy, low-profile termination point for single-family and multi-dwelling installations.

Advantages

The unit provides secure mechanical protection for connectors and fiber splices while maintaining minimal footprint for indoor mounting. Built-in fiber management prevents tight bends and preserves fiber performance. Compatibility with SC simplex and LC duplex connectors allows flexible deployment options for different subscriber equipment. The IP20 protection class ensures suitability for typical indoor environments without exposure to moisture.

Suitable for

• Apartment and home fiber terminations
• Small office FTTH connections
• Subscriber patching points in multi-dwelling units
• Wall-mounted backbone-to-equipment handover

Key specifications

• Connector capacity: up to 2x SC simplex or 1x LC duplex
• Protection class: IP20 suitable for indoor use
• Mounting type: wall-mounted, flush or surface
• Fiber management: integrated bend radius control and splice area
• Material: durable thermoplastic housing for indoor installations
• Color: typically white or light-colored finish for inconspicuous mounting

How to use

Mount the box on a prepared wall surface using the provided fixing points and recommended fasteners. Route the incoming fiber cable into the box through the designated cable entry, secure the cable with the strain relief and arrange fibers along the internal management guides to avoid bending below the recommended radius. Terminate the fibers with SC simplex or LC duplex connectors and insert them into the adapter(s). If splicing is required, use the internal splice area and secure splices before closing the cover. Once connectors are in place and tested, close the housing to protect terminations.

Usage recommendations

For reliable performance, maintain the minimum bend radius specified for the installed fiber type, use appropriate strain relief on incoming cables and perform insertion loss testing after termination. Install the box in a dry, dust-free indoor location and avoid exposure to mechanical stress or moisture beyond IP20 conditions.
