Optoelectronic transceiver modules having photoemitter and photodetector arrays spaced from each other are interfaced to a single optical fiber ribbon having evenly spaced optical fibers. The system also includes a first and second timers configured to measures a time for the parameter of the bit line to decay. The invention also relates to methods for producing a soybean plant containing in its genetic material one or more transgenes and to the transgenic soybean plants and plant parts produced by those methods. Each synchronous receiver output represents the instantaneous input signal power within a specific bandpass filter bandwidth filter.
