Fiber Wavelength Meter Based on Fizeau Interferometer on wFBG for Phi-OTDR Signal Drift Compensation

The paper studies the characteristics of a wavelength meter (WLM) based on a Fizeau-based interferometer (FI) using weak Fiber Bragg Gratings (wFBGs). The proposed WLM is compared with the commercial Angstrom WLM, as well as with a Mach-Zehnder interferometer (MZI) based WLM. The error characteristi...
