Belden FISR288P5, OS2 288 STRAND Plenum Distribution Ribbon Fiber Cable

Belden FISR288P5 is an indoor Plenum OS2 flexible ribbon fiber cable designed for high-density backbone and data center deployments. It features a 288-fiber ribbon construction with 12 active subunits and 24 fibers per subunit, using TIA-598-D color coding for consistent identification. The yellow PVC - Polyvinyl Chloride jacket is rated OFNP and FT6 for Plenum spaces, and the design includes aramid yarns plus an upjacketed GRP central strength member. Optical characteristics include 5,000 m at 1 Gigabit Ethernet and 10,000 m at 10 Gigabit Ethernet (1310 nm).

Belden FISR288P5 Key Features

• Supports high-density fiber builds with 288 fibers organized into 12 active subunits with 24 fibers per subunit.
• Uses TIA-598-D fiber color coding to support consistent identification during installation and maintenance.
• Plenum-rated jacket with OFNP and FT6 flammability / reaction to fire listings for indoor Plenum spaces.
• Built with an upjacketed GRP central strength member and aramid yarns to support strength and handling.
