InLine Glasfiber-duplexkabel LC/ST 50/125µm OM3 20m

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 20m is a multimode duplex patch cable designed for reliable high-speed data transmission over short to medium distances. Featuring a 50/125 µm core/cladding geometry and OM3 fiber specification, the cable supports high bandwidth applications up to 10 Gbps. One end is terminated with an LC connector and the other with an ST connector, enabling compatibility between different types of networking equipment and patch panels. The 20 meter length offers installation flexibility for server rooms, data centers and structured cabling runs.

Advantages

This fiber duplex cable provides low attenuation and controlled modal dispersion thanks to the 50/125 µm OM3 multimode construction, helping to maintain signal integrity for 10 Gigabit Ethernet links. The LC and ST connector combination allows straightforward interconnection of devices and legacy equipment without additional adapters in many setups. The cable’s standardized multimode performance and consistent manufacturing deliver predictable electrical and optical characteristics across installations.

Suitable for

• 10 Gigabit Ethernet links within data centers and server rooms
• Interconnection between switches, transceivers and patch panels with LC and ST ports
• Multimode fiber backbone and horizontal cabling in office networks
• Short- to medium-distance high-bandwidth applications such as storage area networks (SAN)

Key specifications

• Fiber type: OM3 multimode
• Core/cladding diameter: 50/125 µm
• Connector types: LC (one end) to ST (other end)
• Duplex configuration for full-duplex communication
• Cable length: 20 m
• Supports up to 10 Gbps multimode transmission
• Typical use: multimode optical patching and equipment interconnect

How to use

Route the 20 m duplex cable between the two optical ports to be connected, ensuring connectors and transceivers are compatible with LC and ST terminations. Orient and insert the LC connector into LC ports with a gentle push until it clicks; align and insert the ST connector into ST ports by pushing and twisting to secure the bayonet coupling. Avoid bending the cable below recommended minimum bend radius and secure the cable along the route to prevent strain. Clean optical connector end-faces before mating to reduce insertion loss and protect connectors with dust caps when not in use.

Recommendations

For best performance, use appropriate multimode transceivers and ensure patch panels and adapters match OM3 specifications. Maintain minimum bend radius recommendations, keep connectors clean, and test link loss after installation to confirm the cable meets expected attenuation and bandwidth requirements.
