## Summary description

The ACT 12 meter Multimode 50/125 OM3 Polarity Twist fiber cable features LC connectors for reliable connectivity. With a core diameter of 50 µm, it supports high-speed data transmission over short distances, making it ideal for data centers and networking applications. Its polarity twist design ensures optimal performance and reduced signal loss, providing a robust solution for your fiber optic needs.

## Long description

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.
Usage 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.
