Optical fiber wires

Fiber optic cables can be classified into two types, external plant and internal plant,  the latter are better known as jumpers , their characteristics and configurations are usually very different, e function of the outside plant cables is to carry the optical fiber in a safe and reliable way from one point to another, taking into account that Fiber optic cable must resist the ultra violet rays (UV) generated by the sun, resistance to changes weather conditions, being underground or buried in pipelines, or in some cases, the ability to remain submerged underwater for an extended period without water traveling down the cable. Provides protection to the optical fibers against the sun, tree scratches, chemicals and water.

Water blocking tape:  Provides impermeability to the cables through tapes that prevent water from penetrating into the cable.

Cover breaks cord:

 Allows the installer to pull this cord in order to generate a longitudinal cut of the outer cover in order to be able to work with the loose tubes.

Loose tube with gel:

  Protects the optical fibers by means of a gel which blocks the passage of water, likewise identifies the groups of 12 fibers by means of colors. Allows the cable to be hung without the need for a steel guide; The amount of aramid depends on the interpostal length and the load that the cable is going to carry.

Filling tubes:  If the cable has a multiple loose tube design and if a position is not used, it is filled with plastic tubes in order to comply with the construction of the cable.

Central dielectric member:

 It is the reinforced plastic element that provides the cable with tensile strength. Water-blocking thread:  Provides impermeability to the cables through threads that prevent water from penetrating into the interior of the cable.

Optical fibers: Optical fiber of different cores covered by 12-color paint which thickens the fiber from 125 microns to 250 microns which protects it.
