WebMay 12, 2014 · Optical −3 dB bandwidth is set to 20 GHz. Figure 5 b shows the “ through ” port transfer function and its group delay. It is evident that for the latter the dispersion is negligible as the group delay is constant and all the frequency components near to the resonant frequency roughly experience the same “pass-through” time. WebWhen used in an optical communication system, the response time determines the bandwidth available for signal modulation and thus data transmission. Noise-equivalent power Noise-equivalent power (NEP) is the minimum input optical power to generate photocurrent, equal to the rms noise current in a 1 hertz bandwidth.
