InLine Fiber Optical Duplex Cable SC/ST 50/125µm OM3 1m

The InLine Fiber Optical Duplex Cable SC/ST 50/125µm OM3 1m is a multimode patch cable designed for full duplex fiber connections between network devices. It uses a 50/125 µm core/cladding diameter and OM3 graded glass to support high-bandwidth multimode transmission. The duplex format provides two fibers in a single sheath with SC connector interfaces on one end and ST connectors on the other, enabling compatibility with equipment that uses these common connector types. The cable's 1 meter length is suited for short runs in racks, patch panels and between closely located devices while preserving signal integrity for high-speed links.

Advantages

This OM3 multimode duplex cable offers low insertion loss and consistent multimode performance for short- to medium-distance links. The combination of SC and ST connectors allows connection between different transceivers or legacy devices without additional adapter pieces. The 50/125 µm core diameter and OM3 specification support higher modal bandwidth and are suitable for applications that require 10 Gigabit Ethernet and other high-speed multimode protocols. The compact duplex construction simplifies cable management in dense installations.

Suitable for

• Patching between network switches and patch panels in data centres and server rooms
• Connecting multimode transceivers, media converters and legacy equipment with SC or ST ports
• Short-distance high-speed links such as 10 Gigabit Ethernet over multimode fiber
• Laboratory setups, telecom closets and rack-mounted equipment interconnects

How to use

Identify the SC and ST ports on the devices to be connected and ensure both ends are clean and free of dust before assembly. Insert the SC duplex end into the SC port until it clicks, and insert the ST duplex end by aligning the bayonet keyed connector and twisting to lock. Verify that the cable routing does not exceed bend radius recommendations of multimode fiber and avoid crushing or sharp kinks. After connection, test the link with appropriate network diagnostics or fiber test equipment to confirm optical continuity and acceptable loss values.

Recommendations

For reliable performance, keep connector endfaces protected when not in use, use fiber cleaning tools prior to insertion, and avoid excessive bending or mechanical stress. Use this 1 m OM3 duplex cable for short patching runs and pair it with compatible multimode transceivers and devices rated for SC or ST connectors to maintain optimal signal quality.
