Network cable QOLTEC InfiniBand/fibre optic 0.5 m LC–LC, 9 µm core, yellow

QOLTEC InfiniBand/fibre optic 0.5 m LC–LC, 9 µm core, yellow is a short single-mode fibre patch cable designed for high-speed, low-latency interconnects. With LC connectors on both ends and a 9 µm single-mode core, this 0.5 m cable is intended for short patch connections in data centres, storage area networks, high-performance computing environments and telecom racks. The yellow outer jacket provides clear visual identification for single-mode links and simplifies cabling management in dense installations.

Advantages

The cable provides low insertion loss and is suitable for single-mode transmission over short distances thanks to its 9 µm core. Compact LC connectors allow for high-density port deployments while the short 0.5 m length reduces excess slack and helps maintain tidy cable runs. The yellow jacket makes single-mode fibre lines easy to distinguish from multimode runs, aiding rapid troubleshooting and organised patching.

Suitable for

• Short patching between switch ports and transceivers in data centres
• Interconnects in SAN (Storage Area Network) and HPC (High-Performance Computing) environments
• Connecting telecom and network equipment in racks and patch panels
• InfiniBand links and other low-latency fibre optic interconnects

Key specifications

• Cable length: 0.5 m
• Connector type: LC–LC (both ends)
• Fiber type: single-mode
• Core diameter: 9 µm
• Jacket colour: yellow
• Application: short patch connections, high-density installations

How to use

Insert LC connectors into corresponding LC ports on transceivers, switches or patch panels until they click into place, ensuring proper orientation and clean connector end-faces. Use a dust cap when the cable is not connected to protect the ferrule. Route the 0.5 m cable carefully to avoid tight bends and mechanical strain; single-mode fibre requires gentle handling to maintain signal integrity. For installation in cabinets, allow minimal slack to prevent stress on connectors and transceivers.

Usage recommendations

Inspect connector end-faces with a fibre inspection tool and clean with approved wipes or cleaning tools before mating. Avoid bending the cable below the minimum bend radius specified by fibre manufacturers and avoid pulling the cable by the connectors. Use the yellow jacket as part of a colour-coded cabling scheme to separate single-mode and multimode links in the infrastructure.
