<p>An auto optical line switching system of a digital optical repeater donor is provided to switch and recover an optical line to a preliminary optical module automatically without structural change of the donor during fault of an optical module of the donor, thereby seamlessly providing a service of a remote connected through one optical path. A donor(100) comprises plural optical modules(110,120,130), each connected to plural remotes(210,220), and preliminary optical modules. An auto optical line switching device(300) comprises plural optical switches(310,320,330) and a controller(340). The optical switches selectively connect the plural optical modules with the plural remotes. The controller checks an optical module state of the donor, and controls a switching state of the optical switch according to the check result to change a connection structure between the remote and the optical module of the donor.</p> |
