1. A fibre-optic measurement system, comprising:
a controlled light generation system coupled via a first optical path to an input of a directional device;
a receiving system connected via a second optical path to an output of the directional device;
a processing unit for receiving and processing a signal from the receiving system and for implementing an OFDR and/or COTDR measurement technique for measuring changes in an optical distance and processing them into at least one parameter;
a selective mode device for single mode detection of backscattered light coupled via a third optical path to the directional device;
wherein the first optical path, second optical path, and third optical path are all single mode fibres;
wherein the selective mode device is configured to be connected to a multi-mode fiber of a fibre-optic infrastructure; and
wherein the processing unit is configured to control the controlled light generation system, and the selective mode device is configured to selective excitation of a single mode in the multi-mode fibre of the fibre-optic infrastructure to determine an optical distance of the multi-mode fibre.
