InfiniBand / Fibre optic cable QOLTEC 54340 — 3 m, LC to SC, 9 µm core, yellow

QOLTEC 54340 is a 3 m InfiniBand / fibre optic patch cable with an LC connector on one end and an SC connector on the other. The cable uses a 9 µm single-mode core and is finished in yellow for easy visual identification in racks and cable runs. It is designed for point-to-point links in data centres, storage area networks and telecommunications environments where single‑mode fibre connections are required and where low attenuation and reliable high‑speed data transmission are needed.

Advantages

The LC to SC configuration provides compatibility with equipment using either connector type while maintaining small-form-factor LC performance on one end. The 9 µm single‑mode core minimises modal dispersion and supports long-distance, high-bandwidth signals with low insertion loss. The yellow jacket offers standard industry colour coding for single‑mode fibres, simplifying cable management and identification. The 3 m length balances reach and convenience for inter-rack and intra-rack connections.

Suitable for

• Interconnections between network switches, InfiniBand adapters and transceivers
• Storage area network (SAN) links and server-to-switch fibre runs
• Telecom and carrier equipment requiring single‑mode fibre connections
• Patch panels and fibre distribution frames in data centres

Key specifications

• Cable length: 3 m
• Connector type (end A): LC
• Connector type (end B): SC
• Core diameter: 9 µm (single‑mode)
• Jacket colour: Yellow

How to use

Inspect connectors and fibre endfaces for contamination before installation and clean them if necessary using appropriate fibre cleaning tools. Route the cable avoiding tight bends and excessive tension; observe the manufacturer’s minimum bend radius for single‑mode fibre. Insert the LC connector into the LC receptacle and the SC connector into the SC adapter or transceiver port until a secure connection is achieved. Verify link integrity using appropriate test equipment or by confirming network link status after connection.

Usage recommendations

Keep spare protective dust caps on unused connectors, label both ends for easier identification, and avoid routing the cable near strong electromagnetic interference sources even though fibre is immune to EMI. For persistent or long runs beyond intra‑rack distances, evaluate loss budgets and, where necessary, use certified single‑mode transceivers and test the installed link for insertion loss and reflectance.
