Referring to a new type of quasi-reciprocal reflective optical voltage sensor optical circuit structure and according to the environment temperature changes impact on polarization fiber birefringence, a method of constructing ideal reciprocity optical circuit is worked out. In actual application, this method can quickly and accurately identify the best length of measuring optical fiber and compensating optical fiber, and make the light path achieve better reciprocity, which effectively improves the anti-interference ability of the optical circuit. At the same time, the optical circuit can obtain good temperature correlation. The practical application and the production of this kind of optical circuit have a great reference value
