Abstract
In this paper, we proposed an optical bending sensor using an LPG pair that can simultaneously check the degree of bending and bending direction of underground power lines and joints. The 2ch TOSA used as a light source in the proposed sensor system was fabricated using 1570nm and 1590nm CWDM-DBF LD module. The 2ch ROSA for wavelength detection was fabricated using two InGaAs PIN PDs and wave block filters. From the experimental results, it was showed a 10 dB dip change at 1mm bend depth and a peak change at 8 dB at 1.12g / cm2 pressure.
