Collection: OM4 Multimode Bulk Fiber Optic Cables

OM4 50/125 multimode bulk fiber optic cable extends the reach of laser-optimized multimode fiber for high-speed data centers, SANs, and enterprise backbone networks. Primus Cable stocks OM4 bulk fiber in strand counts from simplex to 144 across multiple construction types with plenum, riser, and outdoor-rated jacket options. Available with Corning fiber and bend-tolerant options for demanding high-bandwidth installations.

OM4 Construction Types

Dry loose tube OM4 cable is built for outdoor and indoor/outdoor applications with gel-free water-blocking technology. Distribution OM4 cable uses a tight-buffered design for indoor backbone and inter-building campus runs. Tight buffer OM4 cable provides individual fiber protection for direct termination in patch panels and enclosures. Micro-distribution OM4 cable delivers high-density connectivity in a compact form factor for space-constrained environments. Breakout OM4 cable groups individually jacketed simplex fibers under a shared outer jacket for ruggedized drops with core-locked jacket construction.

Armored Options

Armored OM4 cable is available with CST (corrugated steel tape), AIA (interlocking aluminum), and Micro Armor constructions for direct burial, harsh environments, and rodent-prone areas where physical protection is required.

Jacket & Installation Options

OM4 bulk fiber is offered with PVC, PE, and PVDF jackets across plenum OFNP/OFCP and riser OFNR/OFCR ratings. Indoor, outdoor, indoor/outdoor, direct burial, and aerial applications are supported. Available in simplex, duplex, and multi-strand configurations from 2 to 144 fibers with 1.6mm, 1.8mm, 2.0mm, and 3.0mm diameters for simplex and duplex cables.
