Belden Inc. FD3D048AK OM3 48 Fiber Plenum Cable 12 Foot

Product Description

The BELDEN INC. FD3D048AK is a multimode plenum-rated fiber optic cable assembly designed for structured cabling installations in commercial and institutional buildings. This OM3 laser-optimized cable houses 48 individual fibers in a plenum-rated jacket, making it suitable for air-handling spaces and plenum ceilings where fire and smoke ratings are required by code. At 12 feet in length, it functions as a pre-terminated trunk or breakout assembly used to connect fiber distribution hardware in data rooms, server closets, and telecommunications rooms. Electricians and low-voltage cabling technicians are the typical trade professionals who specify and install this cable.

This cable is used in commercial and institutional environments where OM3 multimode fiber infrastructure is required. OM3 glass supports 10 Gigabit Ethernet and higher-bandwidth applications over appropriate distances. The plenum jacket rating makes it compliant for installation in HVAC air-handling spaces without the need for conduit, reducing installation complexity. Pre-cut at 12 feet, this assembly is suited for short-run interconnects between patch panels, fiber enclosures, and active equipment in structured cabling systems.

Key Features

• OM3 laser-optimized multimode fiber supports high-bandwidth applications including 10 Gigabit Ethernet
• 48-fiber count provides high-density connectivity in a single cable assembly
• Plenum-rated jacket meets fire and smoke propagation requirements for air-handling spaces
• 12-foot fixed length designed for short-run interconnects and equipment room applications
• Sold as individual assembly (quantity per unit: 1)

Compatibility

Designed for use in OM3 multimode fiber optic structured cabling systems. Compatible with standard OM3 multimode fiber termination hardware and enclosures in commercial low-voltage cabling installations.

Installation Notes

Installation should be performed by a licensed low-voltage cabling technician or electrician familiar with structured cabling standards such as ANSI/TIA-568. Fiber optic cables must not be bent beyond their minimum bend radius, and connectors should be inspected and cleaned before mating. When routing through plenum spaces, follow local building codes and NFPA 90A requirements for plenum cable installation. Power down all active equipment connected to the fiber path before disturbing existing connections.
