      This can have an effect with the signal to noise ratio that will show up as attenuation on the signal levels, which are measured in decibels to one milli-watt (dBm). As for the regenerators, they will take the incoming signals, break them down to their electrical properties, clean up the 1’s and 0’s, and convert them back to an optical ...

      dBm/M2 = dBw/M2 + 30 Where the constant 30 is the decibel equivalent of the factor 1000 used to convert between W and mW: 10Log10[1000] = 30. Electric Field to Power Density dBm/M2 = dB V/M - 115.8 Where the constant 115.8 is as follows: P=|E|2/ o Where o is the free space characteristic impedance ( ), equal to 120 .

      Specifically, we often wish to express the power in the units of dB. To do so, we discuss the power relative to a power of 1 watt. Since we are referencing the power to 1 watt we use the units of dBw. Specifically we write. (17) We also often use the term dBm or dB relative to a milliwatt (or mw). The equation for it would be. (18)

      These tests showed that a signal as low as 6.3 dBm EIRP could cause interference at a distance of two meters and that a signal as low as 15.3 dBm could cause interference at a distance of 10 meters. While these tests were limited in scope (only three receivers were tested), they nonetheless provide an empirical demonstration of the potential ...
