A method for overhead processing of optical network and device thereof are disclosed, the device includes: an overhead memory, an overhead processor, and an overhead processor control module. The overhead processor control module is used for controlling the operation of the overhead memory and the overhead processor. The method includes: a system chip inputs the time slots of all overhead bytes that will be processed and descrambled data, and corresponding virtual container numbers, the overhead processor encodes the byte and stores all overhead byte of the same channel in the address of the same overhead memory; at the same time it stores in turn the overhead byte of different channels in different address spaces based on the virtual container numbers, so that an overhead processing logic performs a polling process. The method and device only use a set of overhead processing logic for the overhead of large capacity chips, and save the area and power consumption greatly, thereby reduce the production cost.
