Air blown cable possesses high tensile strength and flexibility in compact cable sizes. At the same time, it provides excellent optical transmission and physical performance. Micro Blown Cables are designed to be used with the Microduct system and installed using a blowing machine for long installations. It is constructed of Fibres inside multiple gel filled loose tubes which range from 12 fibre to 576 fibre cable.
