A novel differential mode delay (DMD) measurement for a multimode fiber based on optical frequency domain reflectometry (OFDR) is proposed. We obtained high-resolution DMD value of 0.054 ps/m for a commercial MMF by our method.
Chromatic dispersion measurement for a multimode fiber using optical frequency domain reflectometry (OFDR) is proposed. A few-mode fiber was prepared to directly measure the chromatic dispersions of the excited modes using our proposed measurement technique.
The mode analysis and modal delay measurement based on the optical frequency domain reflectometry is suggested. Modal delay of few modes fiber is measured by OFDR and is compared with traditional pulse delay measurement method
