Multimode Fiber Cable ACT 3m OM3 Polarity Twist with LC Connectors

The ACT 3m Multimode Fiber Cable OM3 with LC connectors is a 3-meter optical patch cable designed for high-speed short-range data links. It uses a 50/125 µm multimode core with OM3 grading to support increased bandwidth and reliable transmission in LAN, data centre and office environments. The cable's polarity twist arrangement helps maintain correct channel orientation and reduces crosstalk between adjacent fibres. Both ends terminate in LC duplex connectors for compact, high-density connections compatible with standard networking equipment.

Advantages

This multimode OM3 cable offers a balance of flexibility and durability appropriate for common cable management scenarios. The 50/125 µm core with OM3 specification provides improved modal bandwidth over lower OM grades, enabling reliable 10 Gb/s and other short-reach multimode applications. LC duplex connectors provide a small form factor that supports high port density in patch panels and switches. The polarity twist reduces the risk of misrouted channels and helps preserve signal integrity in densely populated racks.

Suitable for

• Short-range data centre interconnects and server patching
• Office network backbone and patch panels
• High-density switch and transceiver connections using LC ports
• Multimode applications requiring OM3 bandwidth for 10G and similar links

How to use

Connect one LC duplex end of the cable to the LC port on your network switch, transceiver or patch panel and the other end to the corresponding LC port on the target device or transceiver. Ensure correct alignment of the duplex pair according to your equipment's transmit/receive orientation; the built-in polarity twist helps maintain the correct channel mapping. Route the cable through cable management channels or trays, avoiding tight bends beyond the specified minimum bend radius for multimode fibers. Inspect connector endfaces for contamination before installation and clean them with appropriate fiber cleaning tools if necessary.

Usage recommendations

Store and install the cable in conditions that avoid excessive tension, sharp bends and physical damage. Use LC-compatible adapters and follow manufacturer guidelines for cleanliness to maintain optimum optical performance. For distances and speeds beyond short-reach OM3 capabilities, verify link budgets and consider singlemode alternatives.
