Transit Time in Fiber Optic Transmission Formulas

Transit time is the duration for a charge carrier to move from where it’s created in the photodetector’s semiconductor material to where it’s collected by the electrodes. And is denoted by t_s. Transit Time is usually measured using the Second for Time. Note that the value of Transit Time is always positive.
