Suppression of modulation instability induced phase noise in the long-haul phase-sensitive optical time domain reflectometry

HIGHLIGHTS

• who: Yichi Zhang and colleagues from the College of Meteorology and Oceanography, National University of Defense Technology, Changsha, China have published the Article: Suppression of Modulation Instability Induced Phase Noise in the Long-Haul Phase-Sensitive Optical Time Domain Reflectometry, in the Journal: Sensors 2022, 8190 of /2022/
• what: In this paper a method of coherent seed injection is proposed to suppress the MI-induced phase noise in long-haul u03a6-OTDR. This work provides an effective method to enhance the input power and extend the range of u03a6-OTDR.
• future: As the . . .
