Belden Inc. FD3H0725G OM3 72 Fiber Optic Cable Assembly

Product Description

The BELDEN INC. FD3H0725G is a hardened outdoor-rated OM3 multimode fiber optic cable assembly configured with 72 fibers. Designed for high-density structured cabling and fiber distribution applications, this assembly supports 10G, 40G, and 100G Ethernet transmission over multimode infrastructure. The OM3 glass specification provides laser-optimized performance suitable for data center trunk runs, campus backbone installations, and industrial network segments where ruggedized construction is required. Licensed network technicians, low-voltage cabling contractors, and data center infrastructure specialists are the primary installers of this product.

This assembly is suited for fiber distribution applications in commercial, industrial, and campus environments. The hardened construction makes it appropriate for installations that face environmental exposure, mechanical stress, or temperature variation. With 72 fibers, it serves high-density backbone runs between distribution frames, intermediate distribution frames, or main distribution areas. It ships as a single unit and is categorized within the fiber optic cable product family.

Installation Notes

Installation should be performed by a licensed low-voltage cabling contractor or qualified fiber optic technician following TIA-568 and applicable local codes. De-energize and power down all connected active equipment before terminating or routing fiber assemblies. Avoid exceeding the minimum bend radius during pulls and routing to prevent signal degradation or physical damage to the glass. Inspect connectors and end-faces before mating to ensure clean optical connections.
