Abstract
The relation of beat frequency, sweep rate, optical frequency modulation excursion and length of fiber under test (FUT) based on tunable semiconductor laser is studied. Experimental results show that the frequency of beat signal will increase when the length of the FUT, optical frequency modulation excursion or sweep rate increases.
