Abstract:
To provide a method and device capable of easily measuring the CMRR vs. frequency characteristics of an optical receiver. Light having a measurement frequency (ω [hz]) is split into two different paths, and a first optical two-tone signal, which is signal light and has a frequency difference (ω−Δω [hz]), and a second optical two-tone signal, which is local light and has a frequency difference (ω-Δω [hz]), are obtained and input into a coherent receiver to be measured, wherein electrical signals output from the receiver are measured to obtain both the ratio of the intensity of a signal component having the frequency ω−Δω [hz] to the intensity of a signal component having the frequency ω [hz], which corresponds to the CMRR on the signal light side, and the ratio of the intensity of a signal component having the frequency ω+Δω [hz] to the intensity of the signal component having the frequency ω [hz], which corresponds to the CMRR on the local light side.

Claim (Index 6):
A common mode rejection ratio measurement device or a method for obtaining common mode rejection ratio, wherein an intensity of a first optical two-tone signal which is signal light and an intensity of a second optical two-tone signal which is locally generated light are preferably equal.
