Paper Abstract

Singlemode-Multimode-Singlemode (SMS) optical fiber structure using multimode coreless have been able to sense changes in relative humidity. In this experiment the measured humidity is 60 % -90 %, while the method is done by comparing the relative humidity changes with the change in output power in the optical fiber. Then the underlying phenomena is the change in the refractive index of air as the cladding MMF coreless due to changes in relative humidity. It has been done three length variations MMF coreless to add sensitivity sensor, and the obtained sensor by 22.30 mm MMF length have the greatest sensitivity, that is 0.0747 dBm / %. Obtained conclusions on length variation will cause any change in the sensitivity significantly in relative humidity between 75 % -80 %.
