摘要： The setting and phase adjusting apparatus for synchronous multiplex communications is provided which adjusts phase differences of main signals caused between a plurality of synchronous multiplexing sections and a line setting section during line setting, in which to reduce the scale of circuitry of the line setting section in a transmission device for carrying out multiplexing and line setting on large-capacity signals, a plurality of pointer modifiers are arranged on a shelf on which the line setting section is arranged. The pointer modifiers connect the line setting section to the respective synchronous multiplexing sections. The pointer modifiers are supplied with multiplexed signals of respective signal series whose data head positions are shifted from one another. The head positions of these signals are synchronized with a timing signal from a timing generator by the pointer modifiers. Line switching is then effected by time switches and a space switch.

摘要： A WDM system includes a plurality of P to P WDM systems connected for wavelength-multiplexing optical signals of a plurality of wavelengths, transmitting them to a transmission path, transmitting wavelength-division multiplexed light while performing amplification by using optical AMP in the transmission path, and subjecting the wavelength-division multiplexed light to wavelength isolation at the reception side. An OSC which is a monitoring control signal such as a normal optical signal is used closely within one P to P WDM system. However, by transmitting and receiving the OSC between a plurality of P to P WDM systems, it is possible to solve a problem at the system rise. Moreover, since accumulative OSNR data is transmitted up to the P to P WDM system of the final stage, it is possible to detect an accurate OSNR value and a leak ASE light quantity at the end side.
