All-dielectric tight-buffered optical fiber cable with an LSZH sheath for riser, indoor, and outdoor applications.
A 24-fiber, gel-filled, dielectric-armored single-mode fiber-optic cable for indoor and outdoor installation.
The cable is available with 2 to 24 fibers in single-mode or multimode types and uses aramid yarns as strength members. Its flexible, fire-retardant LSZH sheath supports higher fire-safety requirements, while the tight-buffered design enables fast field installation and easy jacket removal using standard tools. Standard reel length is 2000 ± 10% m.
