1.2G optical transmission apparatus and method using 155M data switching

摘要

The present invention relates to a 1.2 G optical transmission apparatus using 155M data switching, which multiplexes twenty-four 51M frames of a digital cable TV and adds header data for channel separation to the front of data multiplexed by the 155M, In the optical transmission apparatus, the header data inserted with the channel specific number is added to the front end of the data multiplexed at 155M, and the header data is analyzed at the reception side of the optical transmission apparatus to align the order of 155M data. The data channel of 64Kbps is not used and the reliability of the reception side channel alignment is enhanced by switching the data channel by 155M.
