Noise generated in an optical fiber system by the combination of mode-dependent optical losses and fluctuation in the distribution of optical energy among the guided modes or in the relative phases of the guided modes. Synonym speckle noise.
Industry:Telecommunications
Noise having a frequency spectrum that is continuous and uniform over a specified frequency band. Note: White noise has equal power per hertz over the specified frequency band. Synonym additive white gaussian noise.

Noise having a frequency spectrum that is continuous and uniform over a specified frequency band. Note: White noise has equal power per hertz over the specified frequency band. Synonym additive white gaussian noise.
Industry:Telecommunications
Noise in the audio frequency range, having subjective characteristics analogous to prolonged sibilant sounds. Note: Noise in which there are no pronounced low-frequency components may be considered as hiss.
Industry:Telecommunications
Noise power in dBa referenced to or measured at zero transmission level point (0TLP,) also called a point of zero relative transmission level (0 dBr. ) Note: It is preferred to convert noise readings from dBa to dBa0, as this makes it unnecessary to know or state the relative transmission level at the point of actual measurement.
Industry:Telecommunications
Noise power in dBm, measured with psophometric weighting where where pWp is power in picowatts psophometrically weighted and dBa is the weighted noise power in dB referenced to 3. 16 picowatts.
Industry:Telecommunications
Noise power in dBm0, measured by a psophometer or noise measuring set having psophometric weighting.
Industry:Telecommunications
Noise power in dBrnC referred to or measured at a zero transmission level point (0TLP. )
Industry:Telecommunications
Noise that has a frequency spectrum of predominately zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few random pulses occur while scanning.
