Fiber optics are basically made up of two concentric cylinders (core – cladding) which are made of silicon dioxide (SiO2), in other words, crystal. It is a fragile, breakable material which, although it presents a splendid elastic zone, it lacks plastic deformation, so that it goes quickly from its elastic limit to breakage.
Due to this fragility, the optical fiber must be protected, in order to gain mechanical and environmental resistance.
The light pulses travel through the optical fiber´s core, while its cladding (125µm) acts as a reflector screen, obliging the light beam to travel inside the core. This is possible because the core´s (n1) and the cladding´s (n2) index of refraction are different.

Fundamentally, there are two types of protection for optical fiber:

Primary Protection
It consists of a first coating with acrylate, which is applied on the cladding. This form of protection is universal and is present in all fiber optic cable. The diameter of this protection is usually 250µm.

Secondary Protection
There are two types:

Loose-Tube Protection:
The optical fiber are found inside thermoplastic tubes, in such a way that they fit inside loosely. The tubes are filled with a non-hygroscopic gel. One tube accommodates various optical fiber, meaning secondary protection isn´t applied to each fiber individually.

Tight-Buffer Protection:
This protection is the logical way to proceed. A thermoplastic material cover is fit closely to the fiber´s surface. Each fiber has its own individual secondary protection.

At Optinet S.R.L.,we specialize in the manufacture of optical fiber with Tight-Buffer secondary protection. This kind of technology provides a series of advantages in relation to cable with Loose-Tube protection.


These advantages are:

Superior mechanical protection: Tight thermoplastic protection is applied to each optic fiber, providing mechanical/environmental isolation. Therefore, as a result, excellent resistance to manipulation.

Isolation from humidity by defect: We recommend our report “The Influence of Humidity on the Behavior of Fiber Optic Cable”.

Very flexible and compact finished cable.

Completely dry structure, meaning they do not have gel. The use of chemical elements for the cleaning of optical fiber is not necessary.

They make direct connectorization possible, reducing preparation time and costs noticeably. They do not require termination “breakout kits”.

Universal Interior/Exterior application.

Absolutely fire-resistant optical cable.

Excellent resistance to compression.
