Research On Spectrometer Integrated With OPM

In recent years,with the rapid expansion of the Internet,the capacity,speed and transmission distance of optical fiber communication are also increasing.In order to ensure the effective utilization of bandwidth resources,the channel spacing is gradually narrowed.In the stage of multi-channel high-speed transmission.The technology level of the ROADM has been improved continuously.More and more fields began to apply intelligent optical network,OPM is gradually applied in the construction of optical network.The spectrometer mainly follows the principle of optical dispersion,which is often used to analyze and study the spectrum in practice.It can measure the spectral characteristics of light,especially the strength of spectral characteristics.We hope to improve the cost performance,portability and pertinence of the existing spectrometers,and apply the OPM module in the spectrometers.Based on the diversity of the function of the OPM module,use the OPM module in the spectrometers to develop a lower cost and smaller one Smart,more targeted(for C-band)spectrometer is put into use.In this paper,the OPM module is applied to portable spectrometer as the main function module to complete some of the spectrometer functions we need,mainly through TOF filter and DSP system to process signals,through software algorithm to optimize the firmware.the second chapter mainly introduces the basic composition and optical index of the spectrometer;the fourth chapter mainly introduces the spectrometer How to implement firmware,the implementation principle of some important algorithms,the implementation method of commands,and the way of power calibration;chapter five mainly introduces the production process of the spectrometer and the test results of the spectrum.
