On one principle of monitoring the network of optical transmission systems

The paper considers one new principle of monitoring the network of optical transmission systems. A new scheme of a device for monitoring fiber-optic transmission systems is compiled and the principles of operation of this device are analyzed. Defined technical management of failures as a warning, detection and reaction to malfunctions. Failures are defined as interruptions to the normal operation of the network and include random interrupts, as well as losses of photons (or solitons), intentional interrupts that can be performed by a service failure or eavesdropping. For this purpose, the functionality of the monitoring device and the algorithm for optical networks with different wavelengths have been expanded to be used in backbone, passive optical networks to determine the location of the cliff, the location of the service failure or eavesdropping, and unauthorized attacks. The enhancement capability is based on the study of other optical network elements, such as optical switches, optical multiplexers of input / output, optical cross connections, wavelength converters, optical line terminals, etc. The vulnerability of these elements depends on their architecture and / or manufacturing technology, and therefore, it is possible to consider the different types and forms of attenuation of optical signals, optical line breaks, loss and attack. The new design of the optical switch is applied, as a result, when the failure, attenuation and loss of optical signals are detected, the active port automatically switches to another port and simultaneously reports this to the central terminal device.
