【Abstract】 Above all, this paper briefly introduces the development survey of the instrument without the optical power and its advanced structural research, comparing the domestic and international development condition and development trends.Secondly, this article introduces the optical collimator’s principle fabrication insert loss and return loss, and brings forward the improvement methods of the optical collimator.Thirdly, this article analyses and researches the isolator’s appliance and development, the performance of GRIN, the operation and the principle, the capability and the measure methods, at last the fabrication.Fourthly, this article analyze the principle of WDM, the optical character, propose a novel structure WDM, Measure its character by temperature circling, analyze the technical improvement method of the Novel structure WDM. The result indicates that the novel structure WDM has better stabilize structure andcredibility than the old one.At last, this article introduces the work principle of the new type variable optical attenuator structure and the temperature character. We can obtain the character curve of the novel novel variable optical attenuator’s insert loss against the changing temperature by using the in-line temperature test. In the end we propose the ideal of increasing the optical attenuator’s temperature stabilization by optimizing the fabricate method.更多还原
