InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 25m

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 25m is a multimode duplex fiber cable designed for reliable high-speed data transmission over short to medium distances. With a 50 µm core diameter and OM3 specification, this cable supports enhanced bandwidth for 10 Gigabit Ethernet and other fast networking standards. It comes terminated with two LC connectors on one end and two ST connectors on the other end to enable easy connection between devices with differing port types. The 25-meter length provides flexible routing options in server rooms, data closets, or horizontal cabling runs.

Advantages

This duplex cable combination provides compatibility between LC and ST transceivers and patch panels without additional adapters. The OM3 multimode rating ensures improved modal bandwidth and lower insertion loss for high-speed links compared with lower OM classes. Duplex construction supports full-duplex communication for simultaneous bidirectional data flow. The factory-terminated connectors ensure consistent optical performance and reduce installation time.

Suitable for

• 10 Gigabit Ethernet connections in data centers and server rooms
• Interconnecting switches, media converters, and transceivers with LC and ST ports
• Campus backbone and horizontal multimode fiber runs up to 25 meters
• Laboratory and test environments requiring multimode duplex links

Key specifications

• Fiber type: Multimode (OM3)
• Core/cladding diameter: 50/125 µm
• Connector types: LC (duplex) to ST (duplex)
• Length: 25 m
• Duplex configuration for full-duplex operation
• Typical applications: 10 GBASE-SR and other multimode optical networks

How to use

Inspect connector endfaces for cleanliness before connecting and, if necessary, clean with appropriate fiber cleaning tools to avoid contamination. Align and insert the LC connectors into LC transceivers or adapter ports, and plug the ST connectors into ST-style ports or adaptors, ensuring secure latching. Route the cable to avoid tight bends (maintain manufacturer-recommended minimum bend radius) and protect it from crushing or sharp edges. Verify link status and perform optical loss testing if required to confirm acceptable performance.

Recommendations

Store and handle the cable in a dry environment and avoid exposing it to excessive pulling tension. For best optical performance, keep connector endfaces protected with dust caps when not in use and perform periodic inspection and cleaning. Use this OM3 duplex cable for multimode applications up to the specified length and refer to equipment documentation for transceiver compatibility and supported data rates.
