Abstract
A signal transmission system includes an interface unit that monitors the operating condition of each device. The signal transmission system also includes a simulator that simulates the transmission quality of the system in response to the operating condition of each device, and controls each device so as to optimize the transmission quality.
Claims31
A signal transmission system, comprising:
- a transmitter operable to transmit a signal;
- a receiver operable to receive the signal;
- a transmission line connecting said transmitter and said receiver;
- a first device coupled to said transmission line;
- an interface unit operable to monitor an operating condition of the signal transmission system;
- and
- a simulator operable to simulate transmission quality of the signal transmission system in response to the operating condition, and to control at least one of said transmitter, said receiver and said first device so as to optimize the transmission quality.

A signal transmission system, comprising:
- an optical transmitter operable to transmit a signal light;
- an optical receiver operable to receive the signal light transmitted from said optical transmitter;
- a repeater connected between said optical transmitter and said optical receiver;
- optical fibers connecting said optical transmitter to said repeater and said repeater to said optical receiver, respectively;
- interface units operable to detect predetermined estimation parameters from said optical transmitter, said repeater, and said optical receiver;
- and
- a simulator operable to simulate transmission quality of said optical transmitter, said repeater, said optical fibers, and said optical receiver in response to the predetermined estimation parameters supplied from said interface units and further operable to control at least one of said optical transmitter, said repeater, and said optical receiver so as to minimize a bit-rate error or to maximize a Q-factor.

A method of supervising an optical transmission system comprising:
- transmitting a signal light from an optical transmitter through an optical fiber;
- amplifying the signal light transmitted from the optical transmitter with a repeater;
- receiving the signal light transmitted through the optical fiber via the repeater with an optical receiver and generating an output signal;
- detecting predetermined estimation parameters from the optical transmitter, the repeater, and the optical receiver with interface units;
- simulating transmission quality of the optical transmission system in response to the predetermined estimation parameters supplied by the interface units;
- and
- controlling at least one of the optical transmitter, the repeater, and the optical receiver via the interface units so as to minimize a bit-error rate or to maximize a Q-factor.
