ACT 120m Multimode 50/125 OM4 Indoor/Outdoor Cable 12 Fibers with LC Connectors (RL4712)

For data centre technicians and enterprise network engineers who need a reliable, high-bandwidth link between buildings or across large facilities, this pre-terminated fiber optic cable delivers 12 multimode OM4 fibers in a rugged indoor/outdoor rated jacket. At 120 meters, it is ideal for backbone connections, campus networks, and long-haul runs within a facility.

Why choose it

OM4 fiber supports 10G, 40G, and 100G Ethernet, making it future-proof for high-speed networks. The LSZH jacket ensures low smoke and toxicity in case of fire, suitable for indoor use, while the outdoor rating allows direct burial or aerial installation. Pre-terminated LC connectors save installation time and reduce the risk of field termination errors.

Ideal use cases

• Data centre backbone cabling
• Campus network links between buildings
• High-speed storage area networks (SAN)
• Long-distance runs in industrial environments

Good to know

The cable is supplied as a single continuous length with connectors already attached, ready for immediate deployment. The aqua jacket is standard for OM4 multimode fiber, aiding identification in cable trays.
