摘要: A method and apparatus for implementing optical network quality using bit error rate chromatic dispersion. According to one embodiment of the invention, a includes provision service in wavelength division multiplexing that supports plurality rates. As part this method, cumulative noise dispersion each available path as whole is determined, where an series two or more nodes connected by link on which set wavelengths establishing lightpath. In addition, different grades are distinguished based (BER), BER rate. Furthermore, minimum required decibel penalty, penalty
