EFB Elektronik Splice box LC 50/125µ OM4 extendable Grey Metal 483x244x44.5mm

The EFB Elektronik Splice box LC 50/125µ OM4 extendable Grey Metal 483x244x44.5mm is a wall-mountable fiber optic splice enclosure engineered for organizing and protecting LC 50/125µ OM4 multimode fiber connections. The enclosure offers a metal housing with an extendable design that accommodates splicing trays, patching and cable routing while maintaining mechanical protection and controlled bend radii. Its external dimensions of 483 mm x 244 mm x 44.5 mm provide space for orderly fiber management in data closets, telecom cabinets and network distribution points.

Advantages

The metal construction ensures robust mechanical protection and improved grounding potential compared to plastic enclosures, while the extendable body increases internal capacity without requiring additional wall footprint. The box is designed to support LC connectors and 50/125µ OM4 multimode fibers, enabling organized splicing, secure fixation of pigtails and straightforward cable entry. Compact depth and standard width make it suitable for shallow installations and for integration into existing racks or wall mounts.

Suitable for

• Indoor fiber management in data centres and server rooms
• Telecom and network distribution cabinets
• Horizontal and vertical cabling enclosures where LC multimode terminations are required
• Installation sites requiring compact, extendable splice capacity

How to use

Mount the splice box on a suitable flat surface or inside a cabinet using appropriate fasteners. Open the enclosure and extend the body if additional internal space is required. Route incoming and outgoing fiber cables through the provided entry points, secure cables with strain-relief clamps and prepare fiber ends for splicing. Install splice trays and perform fusion or mechanical splices according to standard fiber handling procedures. Terminate LC pigtails or patch cords into the designated adapter panel and close the enclosure ensuring grommets or seals are properly seated to maintain protection.

Usage recommendations

Handle OM4 fibers with care to maintain bend radius; avoid sharp bends and secure fibers to prevent movement. Use appropriate cable strain relief and follow local grounding practices for metal enclosures. Store unused adapter positions covered to prevent dust ingress and perform regular inspections after installation to verify mechanical integrity and fiber performance.
