Paper Abstract

We propose a novel monitoring method of gain tilt for DWDM (Dense Wavelength Division Multiplexing) submarine cable systems with simple configuration. This method can be applied to DWDM systems on in-service condition without any special devices and dedicated wavelengths. The relation between the measurement sensitivity and pre-emphasis is studied, and we can distinguish more than 4dB gain tilt variation in 25nm transmission bandwidth.
