Optical Fiber Cables

Multitube Armoured

Direct burial cables include Multitube Armoured Cable. It is armoured with high-quality ECCS tape and has multiple loose tubes with fibres filled with thixotropic jelly to prevent water infiltration. Better antibuckling and tensile qualities are offered by fibre reinforced plastic, which also has cable flooding compound placed in the core’s interstices to stop water from entering the core. Available in LSZH and UV HDPE sheaths.
