The two most common outdoor fiber optic wire installations are pole line airborne installation as well as underground cable installment. Underground wire installment can be hidden directly underground or positioned right into a buried air duct.

Direct interment setup:

Direct interment installments are most typical for lengthy cross-country setups. The cords are plowed in or buried in a trench; the installment process can be really quick. The most common wires made use of for straight burial are steel armored outside fiber wires.

Underground air duct installation:

Fiber optic wires can also be pulled through underground air ducts, which shield the wires from rough environment. Below ground air duct installation Fiber optic cable also gives possibility for future expansion without the need to dig. This is one of the most typical practice in city locations. Another benefit is that fiber cables without shield can be used which makes the installation also less complicated.

Preparation prior to underground cable television setup:

1. Obtain proper right of way authorizations

2. Recognize existing underground utilities such as hidden cords, pipes

3. Check out the dirt problem in order to determine the installment deepness, whether duct must be used, the kind of fiber cable need to be utilized and also plowing devices required

Cord Interment techniques:

1. Raked under

Raking in a fiber cable television is much faster than trenched. Yet this procedure has to be carefully kept an eye on to stop from damaging the cord.

2. Trenched

The fiber wire can likewise be trenched. This procedure is slower than raking in; however, it allows a lot more controlled cord installment. Trenches can be dug by hand or by device.

3. Directional boring

Directional uninteresting strategy is utilized where the surface area can not be dealt with such as high, railway crossings, etc. Instead, an uninteresting device is used to birthed a several inches diameter hole beneath the surface area, an air duct is pulling with the opening and then fiber cable televisions pulled right into the air duct.

Important factors:

1. Wire installment depth: approximately 40 inches

The depth that fiber cords ought to be buried is figured out by the dirt conditions as well as surface use. In cooler locations, fiber wires are usually hidden listed below the frost line to stop the cables from being harmed by ground frost heaves.

2. Keep the trenches as straight as possible

Fiber wire trenches should be directly, as well as the trench bottom must be level and also degree. Backfill can also be utilized to distribute the cable tons uniformly and also secure the cable televisions.

3. Fiber cord cautioning tags ought to be buried directly over the cord

Fiber optic warning wires are typically hidden directly over the wires to caution future digging operations. Or concrete pieces can be hidden listed below the warning label yet over the cable televisions to give even more defense.

4. Whenever carrying out armored fiber cords are used, they ought to be properly based

In straight burial installments, steel armored fiber cable televisions are commonly picked for their stamina and also protection from rodent attacks. A very crucial point to remember is to effectively ground the wires. They must be based whatsoever termination points, splices as well as constructing entries. The cord steel armor must be connected to a ground wire making use of a compression-type clamp. The wire ground cord is then bolted to a close-by ground terminal strip
