ACT 17 meter Multimode 50/125 OM3 Polarity Twist fiber cable with LC connectors

The ACT 17 meter Multimode Fiber Cable OM3 with LC connectors is a full-duplex 50/125 µm multimode link engineered for high-speed network environments. The OM3 grading supports laser-optimized performance for short-reach applications, while the 17 m length and LC-to-LC terminations with polarity twist simplify connections between switches, servers and patch panels. The cable construction is designed to deliver low insertion loss and consistent signal integrity across typical data center and enterprise cabling layouts.

Advantages

The OM3 multimode fiber offers improved bandwidth for 10 Gigabit and higher short-range links compared with lower-grade multimode types. LC connectors provide a compact foot-print and reliable mating for high-density panels. The polarity twist configuration allows easy management of transmit/receive mapping without additional adapters. The 50 µm core diameter enables efficient coupling with common multimode transceivers, helping to minimize link loss and support predictable performance.

Suitable for

• Short-reach 10GbE and 40GbE links within data centers
• Patch connections between network switches and servers
• Inter-rack and intra-rack fiber patching in enterprise networks
• High-density patch panels and optical distribution frames

Key specifications

• Fiber type: Multimode OM3
• Core/cladding: 50/125 µm
• Length: 17 meters
• Connectors: LC to LC
• Configuration: Full duplex with polarity twist
• Typical use: Short-reach optical links and patching

How to use

Route the cable through the cable management pathways to avoid sharp bends and mechanical stress. Align and insert LC connectors into the corresponding LC ports until they click into place, observing correct transmit/receive orientation as required by the connected equipment. Use the polarity twist to match Tx/Rx pairs without additional crossover adapters. Secure excess cable length in a service loop and keep connectors capped when not in use to protect endfaces from contamination.

Recommendations

Inspect and clean LC connector endfaces with appropriate fiber cleaning tools before installation. Maintain bend radii above manufacturer-recommended minimums (typically 10× the cable outer diameter for multimode) and avoid kinks. For critical links, verify optical power and insertion loss with a light source and power meter or use certified test equipment to confirm link performance.
