| Abstract(in English) | We characterized transmission of a SCM system using optical repeaters with frequency-block conversion to realize cost-effectiveness by use of standardized transmission equipment and reduction of preparation for lasing wavelength selection of light sources, and to increase transmission length and number of terminals. This system is especially useful to collect video signals from multiple points. In order to characterize transmission performance, CNR effected by optical beat interference derived from simultaneously detecting multiple optical signals transmitted from terminals and an optical repeater, and moreover composite distortions generated at a light source and a receiver in an optical repeater were examined. To practically evaluate this characterization, a SCM system having 2 optical repeaters with frequency block conversion was set up. We confirmed that characterized CNR and composite distortions have a good agreement with measured results. As we certified validity of system characterization, we derived limits of transmission length, number of terminals and number of optical repeats by evaluating CNR and composite distortions. We also demonstrate those results. |
