Belden Inc. FI4D024FJ OM4 24-fiber Riser Fiber Optic Cable

Product Description

The BELDEN INC. FI4D024FJ is an indoor tight-buffered OM4 multimode fiber optic cable configured with 24 fibers in a riser-rated (OFCR) construction. This cable is designed for high-bandwidth backbone and horizontal runs inside commercial and industrial buildings, supporting 40G and 100G Ethernet applications over multimode OM4 glass. The OFCR riser rating meets flame and smoke requirements for vertical shaft and between-floor routing. Licensed low-voltage technicians and structured cabling installers are the primary trades handling this product.

This cable is suited for intrabuilding backbone runs in data centers, enterprise campuses, and multi-floor commercial facilities. The tight-buffered construction protects individual fibers during installation and allows direct termination without a breakout kit, making it practical for both distribution-style and direct-termination installations. The 24-fiber count supports high-density patch panels and MTP/MPO trunk applications common in modern structured cabling systems.

Key Features

• OM4 multimode glass supports 40G and 100G applications at extended reach
• Tight-buffered fiber design allows direct termination of individual fibers
• OFCR riser-rated jacket meets NEC requirements for vertical shaft routing
• 24-fiber count suits high-density backbone and MTP/MPO breakout applications
• Indoor-rated construction for protected intrabuilding environments

Compatibility

Designed as an OEM-style indoor riser fiber optic cable suitable for OM4 multimode structured cabling systems in commercial and industrial buildings.

Installation Notes

Installation should be performed by a licensed low-voltage or structured cabling technician familiar with TIA-568 and NEC Article 770 requirements for optical fiber riser cables. De-energize any active equipment connected to the fiber run before splicing or terminating. Observe the manufacturer minimum bend radius during pulling to avoid micro-bending losses. Do not exceed the cable pulling tension rating during installation through conduit or cable tray.
