摘要
Provided are an optical transmission apparatus and an optical access network for a wavelength-division multiplexing optical network with sub-carrier multiplex and sub-carrier multiple access schemes. The optical transmission apparatus includes: a multiplexer and/or demultiplexer demultiplexing M forward A band optical signals having wavelengths each comprising a plurality of sub-carriers and multiplexing M backward B band optical signals having wavelengths each comprising a plurality of sub-carriers; a plurality of optical power splitters splitting each of the M forward A band optical signals into N optical signals; a plurality of optical receivers receiving backward optical signals belonging to a C band; and M optical transmitters converting the backward optical signals in the C band into the M backward B band optical signals.
