Curvature Loss Optical Fiber Analysis of Head Passive Sensor on the Mandrell Fiber

Abstract

In this research, the curvature loss of optical fiber had been measured to be used as
Head Passive sensors. This measurement produces the data in the form of output power
from varying value of curvature radius. The length of optical cable is 2.173 m, the laser
power is 0.53 mW and the power output of focal lens is 0.26 mW. The data obtained is
an optical output power with radius of curvature from 1 cm until 20 cm. This will be
determined curvature coefficient of weakening or loss. A variation of curvature radius
that was tested from 1 cm to 20 cm with an increment step is 1 cm.
