Modular Cabling
Cable installation by using high speed air flow combined with
additional mechanical pushing force is called as “blowing or jetting”. Cable blowing is the
process of installation of optical fiber cable into a pre-installed duct. Compressed air is injected in the
duct inlet after few hundred meters of cable is pushed into the duct. Compressed air flows at
high speed through the duct and along the cable. The pushing force is applied mainly near the
cable inlet by a pushing device. Standard optical fiber cables (like uni-tube, multi-tube,
unarmored & armored), micro duct cables, and micro-ducts can be installed by using this method. It
is possible to install micro duct cable using blowing method in continuous lengths of more than 1000
meters depending up on the duct route.
