Abstract
An optical frequency transfer device based on passive phase compensation and a transfer method are provided, where the device comprises a local side, a transfer link and a user side. Optical frequency transfer based on passive phase compensation is achieved by simple optical frequency mixing, microwave filtration, and frequency division processing in a passive phase compensation manner, and the device has simple system structure and high reliability.
