Fibre Floating

Cable floating is the process of blowing a cable through a duct while simultaneously pushing the cable into the duct.
Compressed air is injected at the duct inlet and flows through the duct and along the cable at high speed. The high speed air propels the cable due to drag forces and pressure drop.

Fibre Duct Integrity Testing (DIT)

The purpose of DIT (Duct Integrity Test) is to prove that the installed ducts are ready to use for blowing from one manhole to the other. DIT should be performed before blowing to avoid sudden surprises like missing section of ducts, improper coupling, and kink and blockage in ducts.

Fiber Duct Pulling

A common cable installation technique for fiber cables remains cable pulling. After the duct is placed, a high-strength pull line is blown into the duct (if one has not already been pre-installed by the duct manufacturer). The pull line is attached to one end of the cable and is used to pull the cable through the duct.
