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.
