In this paper authors propose methodology to assess lifetime of fiber optic infrastructure (buried cable) based on attenuation measurements. The attenuation measurements were provided as a part of transmission line acceptance tests and then during operation and maintenance routine one year after start of service. Measurements were made on 1310nm and 1550nm wavelengths. Proposed methodology calculates non-refusal work probabilities of fibers in the cable, considering measured attenuation, and estimates expected lifetime. Non-refusal work probabilities are calculated for each single fiber and pairs of fibers assuming fiber backup option. Results showed that expected lifetime of single fibers within particular cable may differ significantly and in order to increase overall reliability correct backup solutions should be found or timely maintenance activities carried out.
