METHOD OF DETECTING A TRANSMISSION FAULT IN AN OPTICAL NETWORK

摘要

Proposed is a method of detecting a transmission fault in an optical network. The method comprises different steps. First measurement data that indicates a first reception level of a first optical signal received at a first optical device is collected. Furthermore, second measurement data that indicates a second reception level of a second optical signal received at a second optical device is collected. The reception levels are monitored by monitoring the measurement data. A transmission fault is detected in the case of an attenuation of one or more of the reception levels. In the case that the transmission fault is detected, a transmission fault type us derived from an attenuation of the reception levels. Then, information indicating the detected transmission fault type is provided. Figure for publication: Figure 4
