Abstract

High resolution and high sensitivity optical components characterization was performed with a jaggedness free coherent optical frequency domain reflectometry (OFDR) with multi-electrode DFB laser. The fading noise was reduced to less than 1 dB by using a double optical frequency sweep, improving the accuracy of insertion loss measurements. Sensitivities down to -105 dB were achieved with minute measurement times
