ACT 12 meter Multimode 50/125 OM3 Polarity Twist fiber cable with LC connectors

The ACT OM3 Multimode Fiber Cable RL8312 is a 12 meter 50/125 µm fiber patch cord terminated with LC connectors and designed for short-range high-speed data transmission. The cable uses OM3 multimode fiber optimized for laser-based equipment and supports typical data center and enterprise networking links. Its polarity twist construction helps maintain correct channel alignment and reduces insertion loss across paired connections, providing consistent optical performance for structured cabling systems.

Advantages

The OM3 multimode construction delivers improved bandwidth and modal properties for 50/125 µm systems, enabling support for higher Ethernet speeds over short distances. LC connectors provide a compact duplex interface that fits high-density patch panels and transceivers. The 12 m length offers flexibility in rack-to-rack and equipment-to-equipment connections without the need for intermediate splices. The polarity twist design simplifies correct mating of transmit and receive channels and can reduce troubleshooting time during installation.

Suitable for

• Data center patching between switches, servers, and transceivers
• Enterprise LAN backbone and server room cabling
• High-density rack installations and fiber patch panels
• Short-reach multimode links for 10GbE and similar applications

Key specifications

• Fiber type: Multimode OM3 (50/125 µm)
• Length: 12 meters
• Connector type: LC duplex
• Polarity: Polarity twist (pre-terminated to preserve channel alignment)
• Application: Short-reach, high-speed data transmission
• Jacket: Standard patch cord jacket suitable for indoor cabling

How to use

Route the fiber cable along designated cable trays or within cable management pathways to avoid sharp bends and mechanical stress. Insert each LC connector into the appropriate LC port on transceivers, switches, or patch panels, observing the duplex orientation and the polarity twist to ensure transmit and receive channels align correctly. Secure excess cable length with appropriate loops inside the rack or patch panel to maintain minimum bend radii and prevent microbends that could increase loss.

Recommendations

Avoid kinking or tight bends; maintain the manufacturer’s minimum bend radius. Keep connector end faces clean — use proper fiber cleaning tools or wipes before mating. Verify link performance after installation with appropriate optical test equipment and document port mapping to reflect the cable’s polarity twist configuration.
