Corning LSZH industrial fiber optic cables are designed for industrial building backbones and harsh environments atypical of traditional datacom systems. Based on proven stranded loose tube cable designs, these industrial cables are flame-retardant and have been tested to meet mechanical/environmental conditions exceeding the requirements set for traditional datacom cables. This ruggedized armored version offers additional mechanical protection and is also available in a gel-filled, cold temperature version. The 250 Um color-coded individual fibers offer quick and easy identification during installation, with 50 Um, 62.5 Um and single-mode versions available. A key benefit of the Corning industrial cables is the low-smoke/zero-halogen (LSZH) shea th.

Corning LSZH industrial cables provide life-safety benefits for industrial applications through the cables’ construction. Many traditional data communication cables contain halogens in the jacket compound, which pose little risk in the controlled and protected environment of typical building air spaces, such as behind walls, under floors and in conduit.
