摘要： The present invention discloses an optical line transmission protection system and method. In which, the optical line transmission protection system includes: at least one stage of optical line protection segment having a transmitting end provided with a Tunable Optical Divide Module (TOD), and a receiving end provided with an OSW; the transmitting end of a local Optical Line Protector (OLP) is connected to the receiving end of an opposite OLP to form main and standby optical lines; and the TOD is configured to set splitting ratios of the main and standby optical lines according to a difference between the optical fiber states of the current working channel and non-working channel, and tune optical power distributions at respective transmitting ends of the main and standby optical lines, according to the splitting ratios of the main and standby optical lines. The embodiments of the present invention simplify the handshake process, improve the switching reliability, and reduce the switching time.
