ADSL - Asymmetric Digital Subscriber Line	Communication technology which allows high speed data transmission (up to 8 Mbit/s) through the network’s copper cables.
Extra-high Voltage	Electric voltage exceeding 150 kV employed in electricity transmission.
Extruded Polymeric Insulation	Insulating material obtained by the extrusion of insulating plastic material.
FTTH - Fiber To The Home	Last mile of connection to homes through fiber optic cables.
FTTP - Fiber To The Premises	Last mile of connection to buildings through fiber optic cables.
FTTX - Fiber To The ‘‘X’’	Last mile of connection to specific locations through fiber optic cables.
High Voltage	Electric voltage ranging between 60 kV and 150 kV employed in electricity transmission from the transmission network to primary distribution.
KV —Kilovolt	Electric Voltage measure unit equal to 1.000 Volt.
Low Voltage	Electric Voltage under (below or equal to) 1 kV employed in electric energy distribution to residential and commercial customers.
LS0H - Low Smoke Zero Halogen	Insulating and/or coating material for medium and low voltage cables.
MCVD - Modified Chemical Vapor Depositation	Technology for the manufacture of fiber optics consisting of a rotating silica glass tube (preform) from which fiber optics are obtained through a spinning procedure. Such technology avoids direct contact between the traversing flame and the silica glass tube. The main advantage of the MCVD technology is that the depositing of the silica soot takes place in clean and uncontaminated grounds.
Medium Voltage	Electric voltage ranging between 1 kV and 60 kV mainly employed in energy distribution through primary and secondary grids.
OEM - Original Equipment Manufacturer	Company which manufactures and markets its own trademark products obtained by purchasing components or finished products from other companies.
OPGW - Optical Ground Wire	Overhead fiber optic cable for high voltage (telecom) transmissions.
OVD - Outside Vapor Deposition	Technology for the manufacture of fiber optics consisting in a rotating silica glass tube (preform) in which, through a flame hydrolytic procedure, the silica soot is deposited on the outside surface of the glass mandrel.
Passive Systems	Telecom transmission systems made of fiber-optic cables or copper cables, electrical junction boxes in which either the optic or electric impulse is passive and not elaborated.
P-Laser	Single step production procedure consisting in the combination of different innovative modules. One of the most important modules consists of isolation, based on extruded thermoplastic materials, which allows employment of more competitive production procedures, for example the insulating procedure in XLPE.
PMD - Polarized Mode Dispersion	Parameter measuring signal dispersion related to the polarization in a fiber optic.
Power Transmission System	Transmission energy system consisting of cables, connections, terminations, installation and protection of urban projects and related testing procedures.
PVC - Polyvinyl Chloride	Thermoplastic material for insulation/external coating of medium and low voltage cables.
Umbilicals	Cables made of electric conductors and flexible tubes (plastic or metallic) used to link offshore oil platforms to submarine oil extraction systems.
VAD - Vapor Axial Deposition	Technology for the production of fiber optics consisting of the manufacture of a rotating silica glass tube (preform) by depositing the glass soot on the bottom end of the rotating silica rod. The preform is continuously pulled upwards during the process due to the growth at the bottom end.
Wire rod	Cylindrical metallic rolled section (copper or aluminum) from the drawing of which basic wires are obtained. These basic wires are used for the manufacture of conductors, by a ropelaying procedure.
XLPE - Cross Linked Polietilene	Electric insulating material made of polymeric chains tied up by chemical bonds (cross-linkage).
