ACT 20 meter LSZH Multimode 50/125 OM3 fiber patch cable duplex with LC and ST connectors

The ACT 20 meter LSZH Multimode 50/125 OM3 fiber patch cable is a duplex fiber assembly with LC connector on one end and ST connector on the other, designed for indoor network links that require reliable multimode performance over moderate distances. With a 50 µm core and OM3 grading, the cable supports high-speed data transmission for structured cabling in data centers, server rooms and enterprise networks. The outer jacket is made from LSZH material to minimize smoke and avoid halogen emissions in case of fire, making it suitable for installation in confined or poorly ventilated areas.

Advantages

This fiber patch cable provides duplex full‑bandwidth transmission with multimode OM3 performance and low insertion loss when terminated with LC and ST connectors. The LSZH jacket reduces toxic fumes and dense smoke generation under thermal stress, improving safety for indoor deployments. A 20 meter length gives flexibility for equipment placement without the need for intermediate splices, while the 50/125 µm core size ensures compatibility with common multimode transceivers and optical equipment.

Suitable for

• Short- to medium-range multimode links in data centers and server rooms
• Connections between switches, patch panels and legacy ST-equipped devices
• Enterprise LAN backbones and campus wiring where LSZH is required
• Temporary or permanent installations that need duplex OM3 performance

Key specifications

• Length: 20 meters
• Connector configuration: Duplex LC to ST
• Jacket material: LSZH (Low Smoke Zero Halogen)
• Polish/type: Suitable for multimode transceivers (factory-terminated)

How to use

Route the duplex cable between the two endpoints, avoiding sharp bends and high-tension points; maintain minimum bend radius as recommended by multimode fiber practice. Insert the LC and ST connectors into their respective ports until a secure connection is achieved. Verify link integrity using optical test equipment or network transceivers, and label both ends to reflect the connected ports for future maintenance. If cable management hardware is present, secure the cable with fiber-friendly ties or organizers to prevent strain on the termination points.

Recommendations

For reliable performance, keep connectors clean and capped when not in use, follow multimode OM3 installation standards for bend radius and routing, and avoid exposing the LSZH jacket to high-temperature sources or mechanical abrasion. Use appropriate fiber testers to confirm insertion loss and optical power levels after installation.
