ACT 20 meter Multimode 50/125 OM3 Polarity Twist fiber cable with LC connectors

The ACT 20 meter Multimode 50/125 OM3 Polarity Twist fiber cable provides a 20 m duplex connection with LC connectors on both ends. Designed for multimode environments, the cable uses a 50 µm core and OM3 graded glass to support high-bandwidth transmission. The polarity twist feature maintains correct signal orientation and reduces crosstalk, which helps preserve signal integrity across data center and enterprise links. This cable is intended for short- to medium-distance multimode networks and structured cabling installations where reliable 10 Gigabit Ethernet performance is required.

Advantages

The cable’s OM3 specification enables 10 Gigabit Ethernet transmission up to 300 meters over multimode fiber, and the 50/125 µm core/cladding geometry matches standard multimode equipment. Dual LC connectors provide compact duplex connectivity compatible with a wide range of transceivers and patch panels. The polarity twist design simplifies correct channel pairing and reduces the risk of incorrect terminations affecting link performance. Overall construction balances flexibility for routing with sufficient protection for typical rack and conduit installations.

Suitable for

• Data center trunking and server farm interconnections
• 10 Gigabit Ethernet links within enterprise LANs
• Patching between fiber panels and transceivers
• Campus backbone and horizontal multimode runs

How to use

Install the cable by routing it through the cable management system and inserting the LC connectors into the corresponding duplex ports on patch panels, transceivers or network equipment. Ensure the connectors are clean before mating to avoid performance loss; use appropriate fiber cleaning tools if necessary. Verify polarity by checking transmit and receive alignment after installation. Secure excess length to prevent sharp bends and maintain the manufacturer’s minimum bend radius to preserve optical performance.

Recommendations

For optimal performance, use this OM3 multimode cable with compatible LC-based transceivers and maintain a bend radius larger than the cable’s specified minimum. Clean connectors before each connection and avoid repeated mechanical stress at connector ends. For runs approaching the upper distance limit for 10 Gigabit Ethernet, validate link performance with an optical tester to confirm loss and continuity.
