Panduit FOJDZ24 24-Fiber OM4 Indoor/Outdoor Riser Cable

The Panduit FOJDZ24 is a 24-fiber OM4 multimode cable engineered for indoor/outdoor backbone deployments where all-dielectric construction and dual environmental ratings are non-negotiable. Built with Panduit's IndustrialNet™ double-jacketed (DDJ) design, this riser/LSZH-rated cable eliminates metallic components entirely, making it the correct choice for aerial runs between buildings, vault-to-IDF risers in high-voltage environments, and installations where NEC 770 dielectric requirements or lightning-path isolation matter. OM4 50µm laser-optimized fiber supports 10GBASE-SR to 550m, 40/100GBASE-SR4 to 150m, and positions your infrastructure for multi-gigabit migration without re-cabling. This is backbone cable for integrators running distributed IP camera networks, access control systems across multiple structures, or AV-over-IP deployments where fiber is the only path that scales.

Key Features

• 24-fiber OM4 (50/125µm) laser-optimized multimode — supports 10/40/100G Ethernet applications with 850nm VCSEL transceivers
• All-dielectric construction — zero metallic components; safe for outdoor aerial spans, eliminates ground-loop and lightning-strike risk
• Dual-rated OFNR/LSZH (Riser/Low Smoke Zero Halogen) — single cable meets NEC riser plenum substitute + IBC/IFC low-toxicity mandates
• Indoor/outdoor environmental rating — UV-resistant black PE outer jacket over aramid strength members and inner buffer jacket
• Double-jacketed (DDJ) design — impact and crush resistance for direct-burial conduit, aerial lashing, or harsh-environment cable trays
• IndustrialNet™ product line — Panduit's industrial-grade fiber platform with extended temperature range and mechanical durability spec
• 250µm tight-buffered fibers — strippable without special tools, compatible with standard LC/SC/ST connectors and fusion splice workflow

OM4 fiber is the current standard for enterprise and industrial multimode deployments because it delivers four times the bandwidth-distance product of OM3 at the same 50µm core diameter. For security and building-automation integrators, this translates to 10GBASE-SR links at full 550-meter reach — enough to connect a head-end in the main equipment room to an IDF in a distant wing or separate structure without active equipment in between. When you deploy high-resolution IP cameras (4K, 8MP+), centralized PoE switching architectures, or fiber-to-the-edge access control panels, OM4 ensures your backbone won't become the bottleneck as camera counts and bitrates climb. The 24-fiber count in the FOJDZ24 supports twelve duplex links, which maps cleanly to a small campus layout (main building + 3-4 outbuildings on a star topology with spare strands) or a high-density single-building riser feeding multiple floors with 2-4 duplex links per IDF.

All-dielectric construction is the defining feature that separates indoor/outdoor cables like the FOJDZ24 from indoor-only riser designs. By eliminating the central strength member (replaced with aramid yarn) and any metallic armor or moisture barrier, Panduit removes the lightning and AC-fault hazard that makes copper or hybrid cables dangerous in aerial or outdoor-conduit applications. NEC Article 770 explicitly requires dielectric cable for installations where the cable could contact power conductors or be exposed to voltage surges; many AHJs also require it for any cable exiting the building envelope. The double-jacket construction layers a rugged black polyethylene outer jacket (UV and moisture resistant) over an inner buffer jacket that protects the 250µm tight-buffered fibers from crush and impact. This design handles direct burial in Schedule 40 conduit, aerial lashing to messenger wire, and indoor cable-tray runs without separate innerduct, making it a true single-SKU solution for building-to-building links that transition from outdoor to riser without splicing or transition boxes.

The dual OFNR/LSZH rating is what allows the FOJDZ24 to legally traverse both outdoor and riser pathways under the same jacket. OFNR (Optical Fiber Nonconductive Riser) is the NEC designation for dielectric riser cable that can run vertically between floors without requiring conduit in non-plenum spaces. LSZH (Low Smoke Zero Halogen) is the IBC/IFC performance standard for cables in occupied spaces where smoke toxicity and visibility matter during fire evacuation — EU and many US municipal codes now mandate LSZH in schools, hospitals, transit hubs, and high-rises. Panduit's compound meets both, so you don't need separate indoor and outdoor SKUs or a splice point at the building entrance. For integrators working on municipal surveillance projects, healthcare campuses, or K-12 school deployments, this dual rating closes the compliance gap and simplifies BOM and labor.

Typical deployment: a county courthouse with an IT room in the basement and IP cameras on perimeter light poles 400 feet away. FOJDZ24 runs underground in PVC conduit (outdoor segment), enters the building through a cable vault, transitions to EMT riser conduit (riser segment), and terminates in an LC panel in the IT room. One cable, one pull, zero splices, full code compliance. Pair with Panduit FZ series LC cassettes or FAP fiber adapter panels for termination, and specify 10GBASE-SR SFP+ transceivers (Panduit PSF1PXA4MBU or equivalent) at each end for a future-proof 10-gig backbone that runs on the same installed fiber.
