Variant:

Fiber optic cable for use in vital communication and emergency systems which needs to be operational during a fire situation
(830°C, 180 min.). The fibers are protected in jelly filled loose tubes stranded around a central strength member to ensure
high performance and long endurance. Individual color for each fiber. 62.5, 50 and 9 μm fibers. The cable can be used outdoor
and indoor, excellent rodent resistance.
