QFNB (QFNI MUD)

QFNB (QFNI + MUD)

Variant:

Fiber optic cable for use in vital communication and emergency systems that must be operational during a fire situation
(90 min. 950 – 1000°C). The fibers are protected in jelly filled loose tubes stranded around a central strength member to
ensure high performance and long endurance. Individual colors for each fiber. 62.5, 50 and 9 μm fibers, MUD resistant jacket.
The cable can be used outdoor and indoor, excellent rodent resistance.
