The two most common outdoor fiber optic fibers

cable installations are pole line aerial installation and underground cable installation. Installation of underground cables can be buried directly underground, or be in a buried pipe.

Installation of underground

Direct landfills are the most common installations Cross Country long. The cables are plowed or buried in a trench, the installation can be very fast. Cable for direct burial commonly used steel armored fiber optic cable in the open.

Installation of underground cables:

Optical fibers can also be through underground pipes, which are taken to protect the cables from the harsh environment. Installation of underground pipes is also an opportunity for future expansion without digging. This is the common practice in urban areas. Another advantage is that fiber optic cables can be used without armor, which makes installation even easier.

Preparing for installation of underground cables:

1. Get a good /> Right of Way
2. Identify underground utilities such as buried cables, pipes /> 3. Inspect ground conditions to determine the depth, either line can be used, the type of fiber optic cable is to be used and the necessary agricultural implements

Cable buried Technical

1. Plowed

Tillage in a fiber optic cable is faster than trenches. But this process must be monitored carefully to avoid damaging the cable.

2. Trench

The fiber can also be determined. This process is slower than in the till, but it allows cables to be controlled much more. The trenches can be dug by hand or by machine.

3. Directional drilling />
Directional drilling technology is used when the surface can be processed as high, level crossings, etc. Instead, use an electric drill, drill a hole, several inches in diameter below the surface is a channel through the hole and fiber optic cables in the Channel drawn.

Important factors:

1. Installation depth Cable: up to 40 inches

The depth that the fiber optic cable should be buried, is determined by soil conditions and the use of surface. In colder areas of fiber optic cables are usually buried below the frost line to prevent the lift cable damaged by ground frost.

2. Keep the trenches right as possible

Fiber optic cable trenches should be straight and the bottom of the trench should be flat and level. The dam can also be used to distribute the load evenly and protecting the wires are.

3. Warning signs must be buried fiber optic cable through the cable />
The fiber optic cables are usually buried warn directly warning of the grave cables future work. Or plates can be buried below the warning sign, but over the cable to provide more protection.

4. be used in the practice of cables armored fibers, they must be properly grounded

In facilities for direct burial, armored steel cables of fibers are often chosen for their strength and protection against bites by rodents. One very important thing to keep in mind is the land of cable. They should be grounded at all end points, splices and doorways. The steel armor cable must be connected to a grounding wire with pliers compression. The body of the cable is then bolted on a strip of ground terminal nearby.

5. Optical fiber minimum bend radius of cable should always be considered for installation.
