Term DEFINITION
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.
