Abstract
A chirping parameter .alpha. in a transmitter is set to a positive value with respect to an SMF that has a positive dispersion value with respect to signal light. A dispersion compensator is provided not only at the receiving end but also at the transmitting end. This achieves a reduction in the number of types of dispersion compensators that should be prepared in advance to optimize transmission characteristics despite the variety in the lengths of transmission fibers.
