Fibre optic cable Lindy 5.0m OS2 LC - ST Duplex

The Lindy 5.0m OS2 LC - ST Duplex Fibre Optic Cable is a 5-metre singlemode cable designed for reliable, low-loss optical connections in networks and data centres. With a 9 µm core diameter and OS2 specification, the cable supports long-distance singlemode transmission and full duplex communication. It uses an LC connector on one end and an ST connector on the other, enabling interconnection between devices and equipment that use these common connector types. The cable jacket is typically yellow to indicate singlemode fibre and the duplex design keeps transmit and receive fibres paired for organised installations.

Advantages

This fibre optic cable offers low attenuation and stable signal transmission suitable for singlemode links. The LC connector provides a compact form factor for high-density patch panels, while the ST connector offers a durable bayonet coupling for legacy and industrial equipment. The duplex configuration simplifies installation for bidirectional links, and the 5.0 m length covers typical rack-to-rack and equipment-to-patchpanel runs without excess slack.

Suitable for

• Singlemode optical connections in data centres and server rooms
• Patch panel to network equipment links where LC and ST interfaces are used
• High-speed, full duplex data transmission over short to moderate distances (up to the practical range for OS2 singlemode)
• Laboratory and test setups requiring a reliable LC-to-ST duplex link

When it may not be suitable

This cable is singlemode (OS2) with a 9 µm core and is not suitable for multimode systems that require larger core diameters and different attenuation characteristics. It is intended for optical links and will not function for copper-based connections. For very short patch leads in high-density multi-fibre assemblies or where both ends require LC connectors, a different connector configuration or length may be more appropriate.

Key specifications

• Length: 5.0 metres
• Fibre type: Singlemode, OS2
• Core diameter: 9 µm
• Connector A: LC (male)
• Connector B: ST (male)
• Configuration: Duplex (two fibres, transmit and receive)
• Cable colour: Yellow (singlemode identification)

How to use

Route the duplex cable between devices that accept LC and ST connectors, ensuring connectors are clean and free from dust before insertion. Align the LC connector with the LC receptacle and insert until it latches; align the ST connector and push in with a quarter-turn to engage the bayonet coupling. Maintain gentle bend radii to preserve optical performance and avoid kinking. Use appropriate cable management and secure the cable to prevent stress on the connectors during operation.

What to consider before purchase

• Verify that your devices or patch panels accept LC and ST connectors respectively
• Confirm that a singlemode OS2 fibre is appropriate for your link distance and equipment
• Check that 5.0 m length matches the intended routing and rack layout
• Ensure your installation provides proper cable protection and bend radius control

Usage recommendations

Clean connectors with appropriate fibre cleaning tools before every connection, avoid tight bends (respect the manufacturer's minimum bend radius), and label both ends of the duplex cable to simplify future maintenance and reduce downtime.
