【摘要】 本文介绍新近研制的0.633μm波段相干光光纤通信系统。该系统采用两个独立的稳频激光器,其中频可在400MHz至2MHz左右任意调谐。系统在70MHz与30MHz中频试通编码信号,实验结果良好。建立这样的系统在国内还是第一次,而中频可谓的相干光光纤通信系统尚未见报道。更多还原

【Abstract】 A coherent optical fiber communication system (0.633μm wavelength) is introduced. This system employs two stabilized lasers working independently, and can tune intermediate frequency (from about 400MHz to 2MHz) arbitrarily. Until now, the coherent optical fiber system which can tune I. F. arbitrarily is not reported yet. With this system selecting I. F. as 70MHz and 30MHz an experiment in transmitting code signals is made, the result is very satisfactory. In our country this is the first experimental system in this field.更多还原
