Fibre optic cable Tecline 85420 20 m 2x ST 2x LC OM2

The Tecline 85420 20 m OM2 fibre optic cable provides a multimode connection with a 50 µm core diameter and full duplex capability. Fitted with two ST connectors on one end and two LC connectors on the other, this 20 metre cable is intended for short- to medium-range network links where OM2 multimode performance is required. It supports high-speed data transmission for networking equipment that accepts ST and LC terminations and is suitable for structured cabling, patching and direct device-to-device links.

Advantages

This fibre optic cable combines ST and LC connector types to enable compatibility with a range of network devices and patch panels. The OM2 multimode construction with a 50 µm core supports reliable signal propagation for typical LAN and data centre distances. Full duplex wiring provides simultaneous bi-directional communication, reducing latency for two-way data flows. The 20 m length gives flexibility for rack-to-rack or room-to-room connections without additional splicing or adapters.

Suitable for

• LAN backbone and horizontal cabling inside buildings
• Connections between switches, patch panels and transceivers
• Data centre short-run interconnects
• Telecommunications closets and equipment racks

Key specifications

• Length: 20 m
• Fibre type: OM2 multimode
• Core diameter: 50 µm
• Connector configuration: 2 x ST to 2 x LC
• Communication mode: full duplex

How to use

Identify the correct orientation for ST and LC connectors and insert each connector into the matching port until it seats securely; ST connectors require a twist-lock action while LC connectors use a latch mechanism. Route the cable to avoid tight bends and excessive tension; maintain the minimum bend radius recommended for multimode fibre to preserve signal quality. Verify link integrity using appropriate optical testing equipment or by confirming network link status indicators on connected devices. For full duplex operation, ensure both transmit and receive pairs are connected correctly between devices.

Usage recommendations

Handle the fibre ends with care and keep protective dust caps on connectors when not in use. Avoid kinking or crushing the cable, and secure it with non-compressive cable management. Clean connectors with suitable fibre cleaning tools before mating to reduce insertion loss. Use this OM2 cable for distances appropriate to multimode performance and pair it with compatible transceivers and ports for reliable operation.
