Belden Inc. HD4B0020220RC OM4 Hybrid Fiber Optic Cable Cmr-of

Product Description

The BELDEN INC. HD4B0020220RC is a hybrid duplex fiber optic cable combining OM4 multimode optical fiber with copper conductors in a single jacketed assembly. The cable integrates 2 OM4 optical fibers and 2 20-gauge copper conductors, making it suitable for installations that require both high-speed data transmission and low-voltage power or signal delivery in one run. The CMR-OF rating qualifies it for riser-rated indoor installations where both fiber optic and communications cable fire codes apply. It is sold as a single unit and is typically handled by low-voltage technicians, structured cabling installers, and licensed electricians.

This hybrid cable is designed for indoor commercial and enterprise environments where consolidating fiber and copper into a single pathway reduces labor and conduit fill. Typical applications include security systems, access control, pan-tilt-zoom camera installations, and audio-visual infrastructure where OM4 bandwidth performance is required alongside a dedicated copper pair for power or control signaling. The riser rating makes it appropriate for vertical runs between floors in commercial buildings without the need for conduit in many jurisdictions.

Key Features

• OM4 multimode fiber supports high-bandwidth applications including 10G, 40G, and 100G Ethernet at appropriate distances
• Hybrid construction combines 2 OM4 optical fibers with 2 copper conductors in one cable assembly
• CMR-OF dual rating meets both riser communications cable and fiber optic cable flame requirements
• Single-run installation reduces conduit space, pull labor, and termination points
• Indoor-rated jacket suitable for plenum-free vertical riser pathways

Compatibility

Designed as an OEM-style replacement or standard-supply hybrid fiber optic cable for indoor riser installations requiring OM4 multimode fiber combined with copper conductors in a unified assembly.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician in accordance with NEC Article 770 for optical fiber cables and applicable local codes. Power down all connected equipment before terminating the copper conductors. Observe the cable's minimum bend radius during pulls to avoid microbending losses in the optical fibers. Do not exceed the rated pulling tension of the assembly during installation.
