Description
Technical Field
The utility model belongs to fiber communication network framework field, concretely relates to communication system from optic fibre to desktop that possesses sensing monitoring function.
Background
Optical fiber sensing, including both sensing and transmission of external signals (being measured). The sensing (or sensitivity) means that the external signal changes the physical characteristic parameters of the light wave transmitted in the optical fiber according to the change rule, such as intensity (power), wavelength, frequency, phase and polarization state, and the change of the measured light parameter is the change of the "sensing" external signal. This "perception" is essentially the real-time modulation of the light wave propagating in the fiber by the external signal. The transmission means that the optical fiber transmits the light wave modulated by the external signal to the optical detector for detection, extracts the external signal from the light wave and processes data, i.e. demodulates, as required. Thus, the optical fiber sensing technology includes both modulation and demodulation technologies, i.e., a modulation technology (or loading technology) how an external signal (measured) modulates an optical wave parameter in an optical fiber and a demodulation technology (or detection technology) how the external signal (measured) is extracted from the modulated optical wave. There are hundreds of existing optical fiber sensing technologies, and physical quantities such as temperature, pressure, flow, displacement, vibration, rotation, bending, liquid level, velocity, acceleration, sound field, current, voltage, magnetic field, radiation, etc. realize sensing with different performances.
