Depending on the type of application they are intended for, fiber optic cables are classified into the following groups of families:
a) optical cables for buried installations;
b) optical cables for installations in ducts or for aerial installations by spinning;
c) self-supporting optical cables for aerial installations;
d) self-supporting optical cables for aerial installations in long spans;
e) optical cables for network terminations;
f) optical cables for indoor installations;
g) optical cords;
Below is a brief description of each type of cable:
DIELECTRIC OPTICAL BURIED CABLE (DE):
Set consisting of single-mode or multimode type optical fibers graded-index coated in acrylate, with protection elements of the basic unit, dielectric traction element, eventual fillers, and core filled with a material resistant to the penetration or propagation of moisture, protected by an internal coating of thermoplastic material, an additional polyamide coating and an outer coating of thermoplastic material. It should preferably be applied buried in direct contact with the soil.

BURIED PROTECTED DIELECTRIC OPTICAL CABLE (DPE):
Set consisting of single-mode or multimode optical fibers graded index, coated in acrylate, protection elements of the basic units, dielectric traction element, eventual fillers; and core filled with material resistant to the penetration or propagation of moisture and protected by a thermoplastic material coating, over which a polyamide coating and an external protection composed of a thermoplastic material duct are applied. It should be applied preferably buried, in direct
