Telegärtner InfiniBand/fibre optic cable 2 m 12x LC Multicolour

The Telegärtner InfiniBand/fibre optic cable 2 m 12x LC Multicolour is a 2-metre OM4 multimode fiber assembly with twelve LC duplex terminations. Designed by Telegärtner Karl Gärtner GmbH for high-density networking environments, this cable supports high-speed InfiniBand and fiber-optic connections where low attenuation and consistent modal bandwidth are required. The multicolour jacket and individually colour-coded fibers simplify identification and routing in racks and patch panels while keeping a compact, factory-terminated profile for immediate deployment.

Advantages

This OM4-rated cable provides improved bandwidth and lower insertion loss over longer multimode links compared with earlier grades, supporting high data rates and reducing the need for frequent signal regeneration. The 12x LC configuration offers a compact footprint for dense installations and easy mapping of multiple channels. Colour coding reduces installation time and error risk during moves, adds and changes. Factory-terminated LC connectors ensure repeatable optical performance and minimise on-site connector assembly.

Suitable for

• Data centre spine and leaf interconnects
• High-performance computing clusters using InfiniBand
• Telecommunications equipment and optical patch panels
• Enterprise aggregation and core switch connections
• Longer multimode links requiring OM4 performance

Key specifications

• Cable length: 2 m
• Fiber type: OM4 multimode
• Connector type: 12x LC (duplex pairs)
• Jacket: multicolour, individual fibre colour identification
• Application: InfiniBand and multimode fibre optic networks
• High-density design for rack and patch-panel use

How to use

Route the cable through cable management channels or racks to avoid tight bends and mechanical stress; maintain the specified minimum bend radius for OM4 multimode fiber. Plug the LC connectors into matching LC ports on switches, transceivers or patch panels, aligning keyed housings and ensuring clean connector endfaces to prevent signal loss. Use the colour coding on the jacket or individual fibers to match transmit and receive channels and to document connections. When disconnecting, pull by the connector housing rather than the cable jacket to protect terminations.

Recommendations

Inspect and, if necessary, clean LC connector endfaces before installation using an appropriate fiber cleaning tool. Avoid tight bends and sharp kinks; secure the cable with Velcro or cable ties without compressing the jacket. Store spare assemblies in protective packaging to prevent contamination. For critical links, verify link performance with an optical test set when installed.
