ACT 12 meter Multimode 50/125 OM4 Polarity Twist fiber cable with LC connectors

The ACT 12 meter Multimode 50/125 OM4 fiber cable with LC connectors is built for high-speed short‑reach data links. It uses a 50 µm core multimode OM4 fiber optimized for 10G and 40G Ethernet and offers consistent attenuation and modal dispersion characteristics suitable for modern networking equipment. The cable’s polarity twist design reduces connector stress and simplifies cable routing in patch panels and switch ports, while the LC duplex connectors provide a compact, reliable interface for dense installations.

Advantages

This multimode OM4 cable delivers stable signal quality over short to medium distances and supports high bandwidth applications. The 50/125 core/cladding geometry offers predictable performance for multimode transceivers and active equipment. LC connectors are compact and widely compatible with common networking hardware, and the polarity twist reduces the need for manual rework during installation. The 12 meter length provides flexibility for rack-to-rack or cabinet-to-cabinet connections without excess slack.

Suitable for

• Data center patching between switches, servers and transceivers
• Enterprise network backbone connections and horizontal cabling
• High-speed links for 10G/40G Ethernet and compatible multimode transceivers
• Telecommunications rooms and structured cabling in office environments

How to use

Inspect connectors and fiber ends for contamination before installation and clean with approved fiber cleaning tools if needed. Route the cable along existing cable management paths, avoiding sharp bends and excessive tension; follow manufacturer bend radius guidelines for multimode fiber. Insert LC connectors into matching LC ports on transceivers, switches or patch panels until a positive click is felt. Verify correct polarity and perform link testing with appropriate fiber testers or transceiver LEDs to ensure expected signal transmission.

Recommendations

Store and handle the cable in a clean environment; avoid touching ferrules. Use dust caps when connectors are not mated and maintain bend radius of the cable to preserve optical performance. For critical links, test insertion loss and return loss after installation to confirm compliance with network requirements.
