ABSTRACT:
The invention relates to a method for monitoring an optical transmission line of an optical data network, wherein light is sent into the optical transmission line at a line input, and backscattered light of said light is detected at said line input and analysed, wherein during normal operation of said optical network, burst mode optical signals carrying a digital payload are sent onto the optical transmission line at the line input, and the backscattered light of said burst mode optical signals is detected at said line input and analysed. The inventive method is simple and cost-effective.
