helos LC singlemode duplex fibre optic network coupler 205558

The helos LC Single-Mode Duplex Network Coupler 205558 is a compact fiber optic adapter designed to join two LC single-mode duplex connectors with precise alignment. It provides a stable physical connection for single-mode fibers in network installations, patch panels and equipment interconnects. The coupler's duplex LC interface helps maintain optical performance while minimizing space usage in racks and enclosure panels.

Advantages

This LC duplex coupler offers reliable fiber alignment and low insertion loss suitable for single-mode links. Its compact duplex format supports high-density installations and simplifies cable routing by keeping paired fibers together. The sturdy housing ensures consistent mating cycles and protection of fiber ferrules, while compatibility with standard LC connectors allows easy integration into existing cabling infrastructure.

Suitable for

• Telecommunication equipment connections
• Data center patch panels and fiber trays
• Server and network equipment interconnects
• Fiber optic wall plates and distribution boxes
• Field splicing enclosures requiring LC duplex interfaces

Key specifications

• Connector type: LC duplex
• Fiber type: single-mode
• Form factor: duplex coupler for mating two LC duplex plugs
• Typical insertion loss: low (designed for single-mode performance)
• Durability: designed for multiple mating cycles
• Mounting: panel or chassis installation compatible
• Material: durable housing to protect ferrules and alignment sleeves

How to use

Install the coupler into a compatible panel cutout or chassis opening aligned with LC duplex ports. Insert LC single-mode duplex plugs into each side of the coupler until they click into place, ensuring correct alignment and secure connection. Verify optical continuity and signal quality using appropriate test equipment. To disconnect, depress the connector latch and withdraw the plug carefully to avoid damaging ferrules.

Recommendations

Handle fiber connectors with clean hands and use fiber-safe cleaning tools to remove dust and contaminants before mating. Avoid bending the fiber beyond recommended minimum bend radius near the coupler and secure cables to reduce strain on the connection. For critical links, perform insertion loss and return loss measurements after installation and use dust caps when ports are not in use.
