Molex PN fiber optic splice enclosure PUH-1SC/APC IP68, weatherproof joint box for single SC/APC adaptor

The Molex PN fiber optic splice enclosure PUH-1SC/APC IP68 is a compact weatherproof joint box designed to protect and organize a single SC/APC adaptor and associated fiber splices. Engineered to IP68 ingress protection, this enclosure provides a sealed environment that resists dust and prolonged immersion, making it suitable for outdoor, aerial, wall-mounted or buried installations where a small, reliable splice housing is required.

Advantages

This enclosure offers a durable, watertight housing that maintains fiber alignment and protects splices from moisture and contaminants. Its compact footprint reduces space requirements while allowing orderly cable entry and exit. Materials and sealing features are selected to withstand harsh environmental conditions and to preserve optical performance by minimizing mechanical stress on fibers.

Suitable for

• Aerial fiber drop points and outdoor distribution nodes
• Wall-mounted patching or junction locations
• Underground or handhole installations requiring compact weatherproof protection
• Field splicing where a single SC/APC adaptor interface is needed

Key specifications

• Ingress protection rating: IP68 for dust-tight sealing and continuous immersion resistance
• Capacity: houses one SC/APC adaptor and associated splice region
• Construction: weather-resistant enclosure designed for outdoor use
• Cable entry: provisions for secure cable inlet/outlet and strain relief
• Mounting options: suitable for aerial, wall-mounted and buried deployments

How to use

Prepare fiber ends according to standard splicing procedures, place splices and the SC/APC adaptor inside the enclosure, and route incoming and outgoing cables through the designated entry points. Secure cables with the provided clamps or strain-relief features, verify splice protection and fiber management within the enclosure, then close and seal the housing to restore IP68 protection. Ensure fibers are not bent beyond their minimum bend radius and that all seals are correctly seated before final installation.

Usage recommendations

For best results, perform installation and sealing in dry conditions and follow industry-standard fiber handling and splicing practices. Verify compatibility of cable diameters with the enclosure’s entry system and periodically inspect seals after extreme weather events to maintain IP68 integrity.
