Connect compatible LC-equipped multimode fiber interfaces across a 150 m run with an OM4 duplex patch cable. The LC-to-LC connector arrangement provides a paired optical path for transmit and receive traffic, making the cable appropriate where both ends of the link use LC multimode fiber connections. Its 492 ft length supports longer in-building horizontal, riser, equipment-room, and cross-room fiber paths without joining multiple short patch cables. OM4 multimode fiber is intended for multimode optical infrastructure rather than single-mode fiber links. This cable fits installations that already have LC multimode transceivers, LC patch panels, or LC fiber adapter panels at each endpoint. The duplex construction keeps the two fibers together as one assembly, which helps maintain paired-path routing between network equipment and structured cabling termination points. FIBER CABLES DIRECT FCDUS279V9431 is distinguished by its 150 m length, OM4 multimode fiber construction, and LC-to-LC duplex connectivity. Select it when the required route length and endpoint connector type are known, and when the installed optical interfaces are specified for multimode fiber. It is a cable assembly for carrying an existing optical link between compatible endpoints; optical modules, patch panels, and other termination hardware are separate components.
