WebIn horticulture, optical efficiency refers to the grow light’s power. This is usually measured in watts per watts (W/W). Since plants tend to be sensitive to the number of photons distributed by the grow light, it is important to maximize optical efficiency. WebJun 7, 2012 · Using a typical value of 8/9 for α, we obtain the optical spectral efficiency factor η of 1.8 Baud/Hz. The optical spectral efficiency becomes 3.6 b/s/Hz if QPSK modulation is used for each subcarrier. The spectral efficiency can be further improved by using higher-order QAM modulation [42,43].
