Abstract: A temperature fiber-optic polarization sensor, which thanks to its nonelectricity, inertness to its surroundings, and high sensitivity is suitable for remote sensing in dangerous environments with a high risk of explosion, can be power-supplied via classical single mode fiber. The research investigates the use of a wavelength multiplex of 1550 and 1557,36 nm, and connections of polarization maintaining circulators, optical routes, and couplers to ensure quality power-supply to the sensor and parallel data transmitting. Separately, without the connected sensor, data transmission was successful without problems. With a connected sensor, due to the whole concept of a circuit caused problems, and data transmission was not working. Sensor sensitivity was tested by the application of a container with water at different temperatures. Experiments show that sensor sensitivity is not negatively affected by data transmission, it only affects the outgoing level of power.
