  • Abstract
    We achieved simultaneous transmission of both stable optical frequency and precise time over real field deployed fiber line. The line was originally deployed by two transmission systems, one operated in C band, second in L band. Within C band system, we created bidirectional 800 GHz wide dark channel and light it up by bidirectional optical amplifiers with single signal path.
