Network Cable Helos LWL 19 inch Splice Box 12 x LC Duplex OM4 375559 black

The Helos LWL 19" Splice Box 12 x LC Duplex OM4 (black) is a rack-mountable fiber optic splice enclosure designed for organizing and protecting fiber terminations in 19" cabinets and racks. It accommodates twelve LC duplex OM4 connections to support high-speed multimode links and provides a compact footprint for dense installation environments. The black finish offers a discreet appearance while the internal layout is arranged to reduce fiber bend and connection stress, helping maintain signal integrity.

Advantages

The splice box supports OM4 multimode fiber and LC duplex connectors, enabling higher bandwidth and extended reach compared with lower-grade multimode options. Its 19" form factor allows straightforward integration into standard racks and patch panels. The enclosure offers protection for splices and patching points, reducing the risk of accidental damage and simplifying cable management. Its compact dimensions make it suitable for installations where space is limited.

Suitable for

• Data center horizontal and vertical fiber distribution
• Server room and telecommunications rack installations
• LAN backbone and high-speed multimode connections
• Fiber patching, termination, and splice management

Key specifications

• Connector type: LC Duplex
• Fiber type: OM4 multimode
• Port count: 12 duplex (24 fibers terminated as LC duplex pairs)
• Mounting: 19" rack compatible
• Color: black
• Function: splice enclosure with organized internal routing

How to use

Mount the splice box into a standard 19" rack or cabinet using the provided mounting points, ensuring it is secured at the appropriate U-height. Route incoming and outgoing fiber cables into the enclosure through the cable entries, secure them with strain relief, and arrange fibers along the internal guides. Perform splicing or terminate pigtails to the LC duplex adapters, then insert LC connectors into the front panel ports. Close the enclosure to protect splices and maintain organized patching access.

Recommendations

Handle OM4 multimode fibers with care to avoid tight bends; follow minimum bend radius guidelines and use proper strain relief. Test connections after installation with an appropriate multimode tester or light source and power meter. Label ports and maintain documentation for rack layout to simplify future changes and troubleshooting.
