A small data network covering a limited area, such as within a building or group of buildings Laser A device that generates coherent electromagnetic radiation in, or near, the visible part of the spectrum LEC Local Exchange Carrier LMDS Local multipoint distribution service. Used to amplify very low signals without contributing significant SNR degradation LNB Low noise block downconverter LO Low Oscillator - Refers to the frequency conversion CW source used in the RF mixing process L0S Line of sight Loss Tangent A value that quantifies the tendency of a material to dissipate energy.
Loss tangent is the measure of the ratio between energy stored and energy dissipated.
LVS Layout Vs. The automated process by which a circuit's physical layout is checked against the netlist of the schematic. This process ensures that connectivity and design parameters match in the two forms of representation. Read our legal notice .
