Abstract

We aim at composing a novel remote monitoring system of the water level and soil humidity under the natural environment with a hetero-core spliced fiber optic chemical sensor inserted into an existing communication line. This paper demonstrates the fusion characteristics of an optical communications and a humidity sensing by means of a hetero-core spliced fiber optic sensor that has been highly-vaunted from the practical perspective. However, this humidity sensor leaks light and attenuates the optical signal power of a communication wavelength by intent on sensing use. From the communications standpoint, this may lead to decrease intensity of optical signals sent to the receiver and increase a bit error. In other words, there may be a trade-off relationship between communications quality and measuring accuracy. We have proved the possibility of the co-existence of communication signals and measuring functions by finding out the effect of humidity sensing on the communications is the optical loss and modal dispersion.
