Patent ID: 8400622

Claim:
A non-transitory computer readable storage medium including a set of instructions that are executable by a processor, the set of instructions, when executed by the processor, causing the processor to perform a method, comprising: collecting a first set of measurement data at a first resolution for a fiber, wherein the first set of measurement data comprises optical time-domain reflectometer traces T back and T forward ; calculating a relative backscatter of the fiber based on the first set of measurement data based on a relative backscatter function η(x)=(10·log 10 T back +10·log 10 T forward )/2; collecting a second set of measurement data taken at a second resolution; calculating a loss along a length of the fiber based on the second set of measurement data; and combining the first set of measurement data with the second set of measurement data to calculate the loss along the fiber at the first resolution.
