Multipath interference test method using synthesized chirped signal from directly modulated DFB-LD with digital-signal-processing technique

Multipath interference (MPI) is detected as a beat spectrum between a multipath signal and a direct signal using a synthesized chirped test signal and measured as low as -78dB for a 3 km single-mode fiber.
