Signal quality information equipment, signal quality evaluation method, an optical signal evaluation system and an optical transmission system

摘要

PROBLEM TO BE SOLVED: To provide a signal quality information apparatus which can shorten an evaluation time and has excellent application flexibility, and a signal adjustment method.;SOLUTION: This signal quality information apparatus 100 is provided with an optical component 110 and an optical output detector 120. As to the optical component 110, an output light intensity P_out is the function of input light intensity P_in, and the function P_out(P_in) has at least one maximum point. An optical output detector 120 detects the time average intensity of output light to be outputted from the optical component 110.;COPYRIGHT: (C)2006,JPO&NCIPI
