Panduit F8RNM5ENNABM100 864-Fiber OS2 Singlemode MPO Trunk Cable Assembly
Overview
The Panduit F8RNM5ENNABM100 is a factory-terminated, 864-fiber OS2 singlemode trunk cable assembly in a 100-meter (328.1 ft) run — built for high-density fiber optic infrastructure deployments where pulling and terminating hundreds of fibers on-site is not an option. The MPO Female connectors on both ends allow direct plug-in to MPO-based patching systems, eliminating field termination labor and the splice loss variability that comes with it. At 864 fibers in a single sheath, this assembly is sized for spine-layer interconnects in hyperscale data centers, large telecommunications rooms, and campus entrance facility crossconnects where aggregate bandwidth demands have outgrown smaller-count trunks.
OS2 singlemode glass (9/125µm) per ITU-T G.652.D delivers the low attenuation and high bandwidth ceiling required for 100G, 400G, and beyond — distance and speed limitations that would constrain multimode simply don't apply here. The LSZH (Low Smoke Zero Halogen) jacket satisfies the flammability and toxicity requirements of plenum-like spaces where halogen outgassing during a fire event is a code or facility concern, while the OFNR rating covers riser-rated vertical pathway installations. This assembly meets TIA-568.3-D, ISO/IEC 11801, and ITU-T G.652.D, so it integrates cleanly into structured cabling programs under any of those governing standards.
Compatibility
The F8RNM5ENNABM100 is compatible with any MPO/MTP-based patching system accepting MPO Female connectors — including Panduit's own fiber optic patch panels and high-density cassette modules, as well as third-party MPO infrastructure from Corning, Commscope, Belden, and equivalent vendors. It integrates into data center cabling architectures using MPO-to-LC or MPO-to-SC fanout modules for breakout to individual transceivers. Confirm that your patching hardware is keyed and polarity-configured to match the female MPO termination on this assembly before installation — polarity method (A, B, or C per TIA-568) must be consistent across the link.
Installation Notes
At 864 fibers, the cable assembly will carry significant weight and bend-radius requirements — verify that your cable tray, innerduct, and support hardware are rated for the fill weight and that bend radius is maintained through all routing transitions. LSZH jackets are less flexible than PVC or plenum alternatives at low temperatures; handle accordingly in cold environments. The factory MPO terminations eliminate field polishing, but connector end-faces should be inspected and cleaned per IEC 61300-3-35 before mating — a single contaminated ferrule in an 864-fiber assembly can degrade an entire MPO ribbon group.
