Product Description
The BELDEN INC. FD4D036PK is a fiber optic distribution trunk cable built to OM4 multimode specifications with 36 individual fibers and an OFNP (Optical Fiber Nonconductive Plenum) rated jacket. OM4 multimode glass supports high-bandwidth applications including 40 Gigabit and 100 Gigabit Ethernet over extended distances. The OFNP plenum rating meets fire and smoke performance requirements for installation in air-handling spaces without conduit. This cable is handled and terminated by licensed low-voltage technicians and structured cabling installers working in commercial and data center environments.
This trunk cable is suited for backbone and horizontal runs in commercial buildings, data centers, and enterprise campus environments where plenum-rated cabling is required by local fire code. The 36-fiber count supports high-density distribution frames and pre-terminated trunk system assemblies. It is typically pulled through ceiling plenums, conduit, and cable trays between distribution points and equipment rooms.
Key Features
- OM4 multimode fiber supports 40GbE and 100GbE transmission
- 36-fiber count for high-density distribution applications
- OFNP plenum-rated jacket meets fire and smoke performance standards for air-handling spaces
- Designed for use in structured cabling backbone and horizontal distribution runs
- Sold as a single unit (EA)
Compatibility
Designed as an OEM-style distribution trunk cable for use with OM4 multimode fiber infrastructure components including patch panels, cassettes, and pre-terminated trunk system hardware.
Installation Notes
Installation should be performed by a qualified low-voltage technician or structured cabling installer in compliance with ANSI/TIA-568 and applicable local fire codes. Power down active equipment connected to the fiber path before terminating or splicing. Do not exceed the cable minimum bend radius during pulling or routing, as exceeding it can cause permanent signal degradation. Plenum-rated cable is required by code in air-handling ceiling spaces and must not be substituted with riser or general-use rated cable in those areas.
