In this work, we present proof-of-concept of a Raman based distributed temperature sensor using standard telecommunication fiber as the sensing element. To allow coexistence with data transmission, a pump source with a wavelength of 1064 nm is used. The proposed DTS is characterized in the range of 20 °C to 100 °C, using the ratio between the Raman band’s powers linearized. We established a characteristic curve of the sensor with a sensitivity of 0.0018±0.0001 /°C, showing that the proposed DTS can detect temperature variations. This work is the first step forward in the development of distributed sensors that coexist with data transmission over the same optical fiber.
