Curvature Analysis in Fiber Optic Cables as a Tilt Sensor Based on Macro Bending

Abstract

The test has been successfully carried out on optical fibers to be used as a macrobending tilt sensor using SMF-28 single mode optical fiber. The optical fiber was molded
with silicon rubber, then connected to a laser light and a power meter to see the intensity of
the laser power produced. The principle is carried out using the macro bending
phenomenon on single mode optical fibers, where the laser light intensity in the fiber optic
cable will decrease if there is a bend or bending in the fiber optic cable. We can observe the
power loss resulting from the macro bending process to find out how sensitive the optical
fiber is to changes in a given angle. The resulting optical fiber sensitivity value is
-0.1534o
/dBm.
