Optical splitter port identification device and method thereof and optical splitter temperature detecting device and method thereof

The invention embodiment discloses an optical splitter port identification device and a method thereof and an optical splitter temperature detecting device and a method thereof. The optical splitter port identification device comprises a grating array, an isothermal packaging box and an identification module. The grating array is positioned in the isothermal packaging box and used to identify wavelength of the light waves which correspond to the light waves formed by the reflection of each grating of the grating array under the reference temperature to each optical splitter port of an optical slitter; the isothermal packaging box is used to make the distribution of temperature in the isothermal packaging box uniform when environmental temperature changes; and the identification module is used to respectively obtain the wavelength of the current reflection light of each grating in the grating array and also the current temperature value. According to the drift relationship of the positive correlated reflection wavelength and temperature of each grating, the corresponding reference reflection wavelength of each grating is obtained; and according to the corresponding relationship between the corresponding reference reflection wavelength of each grating and corresponding optical splitter port identification of the optical splitter, each optical splitter port of the optical splitter is identified. No expensive temperature compensation structure is needed, and extra connection loss and packaging costs produced during the connection of the optical splitter and the grating are reduced.
