Multi Loose Tube structure is made of an assembly of colored tubes around a steel central strength
element. Outdoor cables guarantees the protection of cable where the mechanical damage risk exists
and also to guarantee stability towards environmental influences such as frost and humidity.
The interstices between tubes and central strength member are filled with petroleum jelly to prevent
water penetration. Aramid yarns are helically applied over the tube to provide additional tensile
strength to the cable. Corrugated steel tape armour provides additional mechanical (crush and rodent)
protection with a highstrength ripcord under the armour for easy stripping. Polyethylene (PE) sheath
which is resistant to stress cracking and UV radiation.
