“…The light inside the fiber optics is difficult to get out because the bias index of the glass is greater than the bias index of the air, besides it can be used in humid or wet environments and can be used in the ground. But the shortcomings of the use of fiber optics are the narrow angle range, exponential curves, and weak fiber optic construction so that in its use required a layer of amplifier as protection [16][17][18][19][20]. Based on the background, research will be made on Curving Analysis on Fiber Optic Cable as Macro Bending Based Slope Sensor".…”

The analysis of fiber optics for macro bending-based slope sensors using SMF-28 single-mode optical fibers has been successfully conducted. Fiber optics were treated to silicon rubber molding and connected with laser light and power meters to measure the intensity of laser power generated. The working principle was carried out using the macrobending phenomenon on single-mode optical fibers. The intensity of laser light in fiber optic cables decreases in the event of indentation or bending of the fiber optic cable. Power losses resulting from the macrobending process can be seen in the result of the information sensitivity of fiber optics to the change of angle given. From the results of the study, the resulting fiber optic sensitivity value is -0.1534o/dBm. The larger the angle given, the lower the laser intensity received by the power meter.
