Fibre optic cable Helos 20m OM4 LC/LC

The Helos 20m OM4 LC/LC fibre optic cable provides a 20-metre duplex multimode connection designed for high-speed data transmission. Built to OM4 specifications, the cable uses 50 µm core multimode fibre and LC connectors on both ends to support reliable, low-loss links in network environments that require high bandwidth and stable signal integrity over moderate distances.

Advantages

This OM4 LC/LC cable delivers enhanced bandwidth and reduced modal dispersion compared with lower-grade multimode fibres, enabling higher data rates and longer link lengths within its category. The LC connector format offers a compact footprint suitable for dense patch panels and transceiver ports, while the duplex assembly provides full-duplex communication for typical networking and storage-area-network configurations. The cable construction is aimed at minimizing insertion loss and maintaining consistent performance in rack and patching applications.

Suitable for

• Data centre interconnects and rack-to-rack patching
• High-performance computing clusters
• Server to switch or switch to switch multimode links
• Storage area networks (SAN) and Fibre Channel environments
• Patch panels and optical distribution frames

Key specifications

• Fibre type: Multimode OM4
• Core diameter: 50 µm
• Cable length: 20 m
• Connector type: LC to LC, duplex
• Suitable for high-bandwidth multimode transceivers (e.g., 10G/25G/40G/100G dependent on transceiver and link design)
• Low insertion loss and optimized modal bandwidth for OM4 performance

How to use

Install the Helos 20m OM4 LC/LC cable by connecting the LC connectors to corresponding LC ports on transceivers, switches, or patch panels, ensuring correct orientation for duplex transmission. Route the cable to avoid tight bends and excessive tension; follow standard bend radius guidelines for multimode fibre to prevent increased attenuation. For structured cabling, label both ends for identification and secure the cable within cable management channels or patch panels to maintain consistent performance and ease of maintenance.

Recommendations

Use this OM4 LC/LC cable for short- to medium-distance multimode links where higher modal bandwidth is required. Verify compatibility between the cable and optical transceivers, especially for multi-gigabit links, and inspect connectors for cleanliness before mating to minimize insertion loss and back reflections.
