InfiniBand / fibre optic cable QOLTEC 54290 2 m, SC–SC, 9 µm core, yellow

QOLTEC 54290 is a 2 m InfiniBand / fibre optic patch cable with SC connectors on both ends and a 9 µm core diameter designed for single-mode transmission. The flexible yellow jacket identifies the cable in fibre installations and helps with quick routing and identification in racks and distribution panels. This SC–SC single-mode cable is intended for low-loss optical links in data centres, telecom rooms and high-speed equipment interconnects where reliable point-to-point connections are required.

Advantages

The SC–SC termination ensures a stable, push-pull connection with consistent insertion loss suitable for InfiniBand and other single-mode optical systems. The 9 µm core supports single-mode operation over longer distances with minimal dispersion. A 2 m length provides a practical balance between reach and neat cable management inside racks and patch panels. The yellow outer jacket provides visual identification for single-mode fibre runs and improves cable traceability in complex installations.

Suitable for

• Point-to-point connections between switches, routers and InfiniBand adapters
• Patch panels and fibre distribution frames in data centres
• Telecommunications racks and equipment rooms
• High-speed interconnects requiring single-mode SC–SC cabling

Key specifications

• Cable length: 2 m
• Connector type: SC to SC (both ends)
• Core diameter: 9 µm (single-mode)
• Jacket colour: Yellow
• Application: InfiniBand and single-mode fibre optic links

How to use

Route the QOLTEC 54290 cable between the two SC ports to be connected, avoiding sharp bends and excessive tension. Align and insert the SC connectors until they click into the adapter or transceiver receptacle; the push-pull design secures the connection. Ensure both ends are clean and free of dust before mating to minimise insertion loss and back-reflection. For permanent installations, secure the cable along rack sides or cable management trays to prevent strain on the connectors.

Usage recommendations

Inspect connector endfaces with a fibre inspection tool and use appropriate fibre cleaning supplies before each connection. Maintain a bend radius greater than the manufacturer’s minimum to prevent increased attenuation. Use this SC–SC single-mode cable in indoor, controlled environments such as data centre or telecom rooms to ensure performance and longevity.
