Ground Cable

Basics Indoor Cable Installation fiber optics

Fiber optic cables are exposed to electrical, elements mechanical, chemical and environmental, as appropriate facility is crucial for long-term stability and survival of fiber optic cables.

Cable installation must also meet the NEC (National Electric Code) and local building codes. NEC indicates that fiber optic cables can be placed in the same raceway, the channels of cable tray or enclosure with cable, telephone, communication circuits and Class 2 and 3 of the remote signal.

Note that you should never put the fiber optic cable in the same enclosure that houses electrical terminations.

What are the pipes?

Conduit is a tube or trough for protecting electrical or son and communications cables. It may be solid or a flexible tube which cables are run. They shelter and protect fiber optic cables and any other type of data or communication transmission Online.

Pipes are also called underground ducts and consist of one or more conduits spaced closely together. They are often buried in the ground directly in the concrete shell. Duct lines terminate in underground vaults called manholes. Ducts are made of fiber, PVC, PE and other materials.

Above ground conduits are made of metal or nonmetallic materials. They can be used in locations exposed or concealed locations aboveground.

Characteristics of an installation of Conduct

1. Good properties to withstand the mechanical forces imposed by the installation of cables
2. Observe the fiber optic cable bend radius minimum
3. No edges sharp bends or touches the fiber optic cables throughout the route
4. Meets needs of current and future expansion

What are the media cables?

A cable tray is an assembly of units made of metal or other combustible materials that form a continuous, support rigid fiber cables. Cable trays are used in industry and they greatly simplify the installation of fiber optic cables.

Cable trays are of different types including scale type, the type of vessel, type of channel and type solid-bottom.

On cable ladder type plate is a metal structure composed of two longitudinal side rails connected by individual transverse. The cross members provide support for fiber cables.

Cable Trough-type tray is a metal structure. It consists of a broken back and close media Within litters integral or separate longitudinal.

Channel type cable consists of a tank of a single ventilated room or section of a solid channel bottom.

Solid-bottom type of cable tray is a metal structure which has no openings in the background. Longitudinal stringers integrated or separated, provide support for fiber optic cables.

What are the pull boxes?

Pull boxes are used to break long duct lengths for easier cable and lower the tension pulls.

Pull boxes are generally placed near conduit elbows and long straight runs. You must use at least one pull box after every second 90 ° bend and led span long.

When pulling cable out of pull boxes, to ensure that minimum cable bend radius is always respected. Heatshrink through a pull box angle must first be drawn into a loop from the acute angle of the pull box can easily damage the cable and fiber.
