Belden FISB004PB is an indoor OS2 breakout fiber cable designed for horizontal backbone runs where clean sub-unit fanout and reliable single-mode performance are required. It features 4 fibers in 4 active subunits with 1 fiber per subunit, using 0.078 in (2.0 mm) sub-units and a yellow PVC - Polyvinyl Chloride jacket. The construction includes aramid yarn strength members, a GRP central strength member, and a Nomex Tape core wrap. It is rated OFNP, FT6 and supports low attenuation performance at 1310 nm and 1550 nm.
