摘要： During initial start-up of an optical communication system, an ASE reference span loss is calculated based on transmitting power and received power of ASE light generated by an optical amplifier, and an OSC reference span loss is calculated based on the transmitting power and the received power of OSC light. During normal operation of the optical communication system, a span loss is calculated using the OSC light, and an amount of change in the span loss representing a difference between the span loss and the OSC reference span loss is calculated. A current span loss between a transmitting station and a receiving station is calculated by adding the amount of change in the span loss to the ASE reference span loss.

摘要： A method for switching a transmission route in an optical network. A regenerator station extracts a main signal, and detects the input level of the main signal. When the input level falls below a threshold, the regenerator station determines that a failure occurs, and stops output of a main signal from the regenerator station, and transmits a control signal indicating occurrence of the failure to a receiver station, which separates the control signal from a main signal transmitted thereto, detects the input level of the main signal at the receiver station, analyzes the separated control signal, and determines whether or not a failure occurs. When the input level of the main signal at the receiver station falls below a threshold, or when the separated control signal indicates occurrence of a failure, the receiver station detects the occurrence of the failure, and switches the transmission route.

摘要： An optical transmission network includes a first dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value and searched out from within a maximum dispersion route having a maximum dispersion value from among routes of non-regeneration intervals within which a dispersion value before dispersion compensation does not satisfy an upper limit of a dispersion tolerance, and a second dispersion compensator arranged in a maximum dispersion span having a maximum dispersion value searched out from within a maximum dispersion route having a maximum dispersion value from among the routes when a dispersion compensator is successively arranged until a route of a non-regeneration interval within which a dispersion value of a certain channel does not satisfy the dispersion tolerance does not remain any more based on the dispersion value after the dispersion compensation with respect to the searched out maximum dispersion span. The dispersion compensation amounts of the first and second dispersion compensators are such that, when the dispersion compensation amount of the maximum dispersion span in which the first and second dispersion compensators are arranged is successively increased, the span has a residual dispersion value equal to or higher than a fixed range and the maximum dispersion route which relates to the spans has a residual dispersion value which satisfies the dispersion tolerance or the span has a residual dispersion value which is within the fixed range.
