Claim 8:
9. The OTDR method as claimed in claim 2,
wherein each one of said plurality of optical fiber links is connected in loop between a first launch/receive fiber connected at its first end and a second launch/receive fiber connected at its second end;
wherein the step of performing an OTDR acquisition comprises performing a first OTDR acquisition from said first end of said one of said optical fiber links so as to obtain a first OTDR trace;
wherein said set of backscattering patterns comprises said one backscattering pattern that is extracted from a second OTDR trace acquired from said second end of said one of said optical fiber links and corresponds to at least a portion of said second launch/receive fiber; and
wherein the step of searching comprises searching in said first OTDR trace, for said one backscattering pattern, to determine if said first OTDR trace matches said second OTDR trace;
wherein a link continuity between said first end and said second end is determined when a match is found.
