摘要：
A method for operating a redundant optical communication network has at least two network transmission paths, assigns first and second protection protocols to switched signals and secondary signals respectively, adds and drops the switched signals and secondary signals on the at least two network transmission paths, makes the switched signals and the secondary signals to counter-propagate along the at least two network transmission paths, therefore, the redundant optical communication network can support different data types and different protection mechanisms. An optical communication network configured by the method of the present invention includes at least two network transmission paths, a first and a second processing means for processing switched signals and secondary signals in accordance a first protection protocol and a second protection protocol respectively, a primary and a secondary add/drop mechanisms for selectively adding and dropping the switched signals and secondary signals to counter-propagate along said at least transmission paths. The network can support different data types and different protection mechanisms.
