We have designed and developed an optical refractive index sensor, optical temperature sensor and optical quasi distributed network based on standard multimode telecommunication graded index fiber for measurements of refractive index and temperature. Special attention was given to inter - dependence of different parameters and their influence on losses, cross talk and modulation depth of individual sensors in the network. Based on the thorough analysis of all the influential parameters on the behavior of the network, a model thatenables design and development of optical networks based on optical evanescent sensors with decreased cross talk could be derived. The model was evaluated with a practical design of two quasi distributed sensor networks that were constructed of previously designed single point sensors. One networkwas constructed for measurements of refractive index while the other enabled measurements of temperature.
