Belden Inc. FI4B004PBA OM4 4-fiber Plenum Fiber Optic Cable

Product Description

The BELDEN INC. FI4B004PBA is a multimode plenum-rated fiber optic cable designed for structured cabling installations where fire code compliance is required in air-handling spaces. This 4-fiber assembly uses OM4 multimode glass, which supports high-bandwidth applications including 10G, 40G, and 100G Ethernet over longer distances compared to OM3. The OFNP rating qualifies it for plenum spaces without conduit, meeting fire spread and smoke emission requirements under the NEC. It ships in an aqua jacket, which is the standard industry color code for OM4 multimode fiber.

This cable is suited for horizontal and backbone runs inside commercial and institutional buildings where plenum air-handling ceiling or floor spaces are part of the pathway. Typical installations include data centers, office buildings, healthcare facilities, and education campuses. The 4-fiber count makes it appropriate for point-to-point links, small trunk runs, or any application where a compact fiber count is sufficient. It is installed by licensed low-voltage contractors, structured cabling technicians, and data communications electricians.

• OFNP plenum rating meets NEC requirements for installation in air-handling spaces without conduit
• 4-fiber count suits point-to-point and small trunk cabling runs
• Aqua jacket follows TIA and ISO color coding standards for OM4 multimode fiber
• Sold per unit (each), with a quantity of 1 per unit of measure

Compatibility

Designed as an OEM-style plenum multimode fiber optic cable suitable for structured cabling systems requiring OM4-rated 4-fiber OFNP assemblies in commercial or institutional environments.

Installation Notes

Installation should be performed by a qualified low-voltage cabling technician in accordance with NEC Article 770 governing optical fiber cables. Verify that plenum pathway clearances and bend-radius minimums are maintained throughout the run before pulling. Terminate using appropriate OM4-compatible connectors and test insertion loss with a calibrated optical loss test set per TIA-526 standards. Do not exceed the cable's minimum bend radius during installation, as kinking can cause permanent signal degradation.
