METHOD AND ARRANGEMENT FOR IN SERVICE RAMAN GAIN MEASUREMENT AND MONITORING
Abstract:
The invention refers a method and an arrangement for in service Raman gain measurements and monitoring of a wavelength division multiplex system. By measuring the power level values of a transmitted WDM signal (WMS_TX) and an optical supervisory signal (OSS_TX) at the transmitter and the power level values of the received signals (WMS_RX; OSS_RX) the Raman gain can be calculated for the different channels.
Abstract(Chinese):

本发明涉及用于在线拉曼增益测量和波分复用系统的监视的方法和装置。 通过测量发射机发射的WDM信号（WMS_TX）和光监控信号（OSS_TX）的功率电平值和接收信号（WMS_RX; OSS_RX）的功率电平值，可以为不同的信道计算拉曼增益。
