Naolin Infra Underground Fiber Optic Cable Installation expertise and methods adopted for successful fool proof installations.

Direct burial installation:

Direct burial installations are most common for long cross-country installations. The cables are plowed in or buried in a trench; the installation process can be very quick. The most common cables used for direct burial are steel armored outdoor fiber cables.

Underground duct installation:

Fiber optic cables can also be pulled through underground ducts, which protect the cables from harsh environment. Underground duct installation also provides opportunity for future expansion without the need to dig. This is the most common practice in urban areas. Another benefit is that fiber cables without armor can be used which makes the installation even easier.

Preparation before underground cable installation:

• Obtain proper right-of-way permits

• Identify existing underground utilities such as buried cables, pipes

• Investigate the soil condition in order to determine the installation depth, whether duct should be used, the type of fiber cable should be used and plowing equipment needed

Cable Burial Techniques:

1. Plowed under

Plowing in a fiber cable is faster than trenched. But this process has to be carefully monitored to prevent from damaging the cable.

2. Trenched

The fiber cable can also be trenched. This process is slower than plowing in; however, it allows a much more controlled cable installation. Trenches can be dug by hand or by machine.

3. Directional boring

Directional boring technique is used where the surface cannot be worked on such as high, railway crossings, etc. Instead, a boring machine is used to bore a several inches diameter hole underneath the surface, a duct is pulling through the hole and then fiber cables pulled into the duct.
