Abstract
A differential mode delay (DMD) measurement system for an optical fiber is provided. The system includes an optical test fiber with a plurality of modes; a single mode light source that provides a continuous light wave signal to a modulator; and a pulse generator that provides an electrical pulse train signal to the modulator and a triggering signal to a receiver. The modulator is configured to generate a modulated optical test signal through the optical fiber based at least in part on the received light wave and pulse train signals, and the receiver is configured to receive the test signal transmitted through the fiber and evaluate the test signal based at least in part on the triggering signal. The system can be employed to create DMD waveform and centroid charts to obtain minEMBc bandwidth information for a fiber within a wavelength range.
