InfiniBand / fibre optic cable QOLTEC 54037, 3 m, SC to LC, 9 µm core, yellow

QOLTEC 54037 is a 3 m InfiniBand/fibre optic patch cable with an SC connector on one end and an LC connector on the other. Designed for single-mode transmission, the cable uses a 9 µm core and is finished in yellow to simplify visual identification in racks and cabling runs. The LSZH outer sheath reduces smoke and harmful gas emission in case of fire, and each unit is individually tested to ensure reliable performance for high-speed data links in networking, storage and telecom equipment where SC–LC connections are required.

Advantages

The single-mode 9 µm core supports long-distance, low-attenuation links and stable optical performance. SC-to-LC termination allows compatibility between different equipment types and patch panels without additional adapters. The 3 m length is convenient for typical rack-to-equipment or shelf-to-panel connections, while the yellow jacket enables quick visual tracing of single-mode runs. The LSZH jacket improves on-site safety by limiting toxic emissions in case of fire, and individual testing provides quality assurance for deployment in production environments.

Suitable for

• High-speed InfiniBand links between servers, switches and storage systems
• Single-mode fibre connections in telecom and data center fiber trunks
• Patching between SC-terminated panels and LC ports on active equipment
• Structured cabling installations where clear cable identification is needed

Key specifications

• Cable length: 3 m
• Connector types: SC (one end) to LC (other end)
• Core diameter: 9 µm (single-mode)
• Jacket colour: yellow for single-mode identification
• Sheath type: LSZH (low smoke, zero halogen)
• Intended use: InfiniBand and fibre optic high-speed data transmission

How to use

Route the cable between the SC-terminated panel or transceiver and the LC port on the destination device, avoiding sharp bends and excessive tension. Align and insert the SC connector into the SC adapter or socket until it clicks into place, then insert the LC connector into the LC port with the duplex clip oriented correctly. Ensure connectors are clean before mating; if necessary, use a suitable fibre cleaning tool or lint-free wipes with approved cleaning solution. Verify link status on network devices after connection and manage excess cable length to maintain bend radius recommendations.

Usage recommendations

For reliable performance, keep the minimum bend radius specified by the cable manufacturer, store and handle connectors with dust caps when not in use, and perform visual inspection and cleaning of end faces prior to installation. Use the yellow jacket as part of your cable identification scheme for single-mode links in racks and trays.
