Fibre optic cable Synergy 21 S217028 15 m OM4 2x LC

The Synergy 21 S217028 15 m OM4 fibre optic cable with dual LC connectors is designed for high-speed short to medium reach data links. With a 50 µm core diameter and OM4 multimode classification, this cable supports full duplex communication and is suitable for modern network infrastructures requiring low attenuation and high bandwidth density. The 15 metre length offers flexibility for patching between racks, switches and transceivers while maintaining signal integrity for applications that rely on multimode optics.

Advantages

This OM4 fibre cable provides enhanced bandwidth performance compared with lower-rated multimode fibres, enabling higher data rates and extended reach for multimode transceivers. The dual LC connectors allow for reliable duplex connections in compact duplex ports. Its 15 m length balances reach and manageability, reducing the need for additional patching while maintaining neat cabling runs. The 50 µm core ensures compatibility with a wide range of multimode SFP+, SFP28 and other multimode modules used in enterprise and data centre environments.

Suitable for

• Patch connections between network switches and servers in data centres
• Interconnects for SAN, NAS and storage arrays using multimode optics
• Fiber links in telecommunications rooms and network cabinets
• Short- to medium-reach optical connections for high-speed LANs

How to use

Connect each LC connector to the corresponding LC port on network devices, ensuring correct polarity for duplex transmission. Route the cable through cable management systems or along rack channels to avoid sharp bends; maintain the manufacturer’s minimum bend radius to prevent increased attenuation. For installation, verify transceiver compatibility with OM4 multimode fibre and perform optical loss testing or link verification after connection to confirm acceptable insertion loss and end-to-end signal performance.

Recommendations

Store and install the fibre cable in a clean environment; cap disconnected LC connectors to protect endfaces from dust and contamination. Avoid tight bends, kinks and excessive tensile force during installation. When used in high-density racks, label both ends for easy identification and test links after installation to ensure reliable multimode performance.
