Fibre optic cable Helos 5m OM4 LC/LC

The Helos 5m OM4 LC/LC fibre optic cable with a 50 µm core is designed for full duplex data transmission over short to medium distances. Constructed to support high-speed networks, this OM4 multimode cable provides low insertion loss and consistent optical performance for connections between network equipment, transceivers and patch panels. Its LC/LC connector configuration makes it compatible with a wide range of switches, servers and active modules commonly used in data centers and enterprise networks.

Advantages

The OM4 rating and 50 µm core diameter enable higher bandwidth and longer reach compared with lower grade multimode fibres, supporting applications such as 10G, 25G and 40G Ethernet over short distances. The LC/LC duplex termination provides a compact connection footprint and reliable mechanical mating. The 5 m length offers flexibility for rack-to-rack and patching scenarios while keeping signal attenuation minimal. The cable is suitable for standard patching environments and structured cabling installations.

Suitable for

• Data center patching between switches, servers and transceivers
• Server room connections and rack-to-rack links
• High-speed multimode Ethernet links (10G, 25G, 40G where supported)
• Optical transceiver testing and lab setups

Key specifications

• Core diameter: 50 µm multimode (OM4)
• Connector type: LC to LC duplex
• Length: 5 m
• Transmission: full duplex
• Typical application: short to medium multimode links, data center patching
• Optical performance: designed for low insertion loss and consistent modal bandwidth characteristics

How to use

Insert each LC connector into the corresponding LC port on network equipment, ensuring the duplex clip orientation matches the transmit/receive alignment of connected devices. Route the cable to avoid sharp bends and mechanical stress; maintain recommended bend radius for multimode fibre to minimize attenuation. For secure, repeatable connections, verify connectors are clean before insertion and follow standard fibre handling procedures during installation and maintenance. Label both ends if used in structured cabling to simplify identification.

Recommendations

Use appropriate fibre cleaning tools before each connection to prevent contamination-related loss. Avoid kinking and do not exceed the specified bend radius. When used in high-density racks, employ cable management to prevent stress on connectors. Verify compatibility of connected transceivers with OM4 multimode fibre for optimal link performance.
