Before we can begin physical trenching work in an area, we need to plan where our core route cable will run, where the cables that will connect each business installation site, will be placed and where we will place each manhole. We need to do this for every meter that we physically construct.
We then need to submit this plan to the required government institution in order to get permission to undertake the project.
After our plan has been approved by all concerned parties, we can then begin the work of laying our fiber. We start the work by first digging up the sidewalk and then laying the empty ducts using HDD machines that will make up the core route cables, as well as the duct that will go to each installation site.
This is performed on the same day so that we can fill the trench back in. During this time our manholes are also installed to allow us to connect site to our network.
Blowing the fiber
After the empty ducts have been laid (and duct integrity has been vetted), we can then start blowing the fiber through the ducts. We use high pressure air to push the fiber through the empty ducts between manholes.
We can then connect the fiber to other manholes by joining two sections of fiber to each other. This is done by fusing the fiber (glass) strands to each other.
The moment we are certain that all the duct integrity has been maintained through the trenching process, we can then reinstate the tar, paving or unpaved ground and return the road at a bare minimum to its original state but usually to a state better than we found it.
