ACT 7 meter Multimode 50/125 OM4 Polarity Twist fiber cable with LC connectors

The ACT 7 meter Multimode 50/125 OM4 Polarity Twist fiber cable with LC connectors is designed for high-speed short-range optical links. The cable uses a 50 µm core multimode OM4 fiber optimized for enhanced bandwidth over multimode links, and comes terminated with 2x LC connectors on each end using a polarity twist configuration to match equipment wiring needs. This 7 m patch cable is intended for structured cabling in data centers, server rooms and high-performance network racks where reliable multimode connectivity is required.

Advantages

This OM4 multimode fiber cable delivers low attenuation and consistent insertion loss across typical multimode wavelengths, helping maintain signal integrity for 10 GbE, 40 GbE and other short-reach links. The LC connector termination offers a compact duplex form factor for dense patching panels and transceivers. The polarity twist wiring simplifies connection alignment between duplex ports, reducing the chance of cross-pair errors during installation and maintenance.

Suitable for

• Data center patching and cross-connects
• Server-to-switch and switch-to-switch short-range links
• High-density patch panels and optical distribution frames
• Multimode transceiver connections (LC duplex)
• Enterprise LAN backbone and aggregation links

Key specifications

• Fiber type: Multimode OM4, 50/125 µm core/cladding
• Length: 7 meters
• Connector type: LC duplex on both ends
• Polarity: Twist (pre-configured for duplex alignment)
• Attenuation: Low-loss multimode performance at common wavelengths (850/1300 nm)
• Cable jacket: Flexible jacket suitable for indoor use and rack routing

How to use

Route the 7 m OM4 cable between LC duplex ports on equipment, patch panels or transceivers, ensuring minimal bending and avoiding tight loops around sharp edges. Verify connector cleanliness before mating; use approved fiber cleaning tools to remove dust and contamination from ferrules. Insert the LC connectors into the corresponding duplex ports, confirming the polarity orientation with the polarity twist to match the transmit and receive pairs. After connection, secure any excess cable in cable management trays or organizers to maintain bend radius and prevent mechanical stress.

Recommendations

Maintain recommended minimum bend radius and keep LC connector endfaces clean; test links after installation with appropriate multimode optical test equipment to confirm loss and continuity. Use this OM4 50/125 cable for short-reach high-bandwidth links where multimode performance is specified, and replace connectors if endface damage is detected.
