The monitoring of the optical fiber infrastructure, especially within the intra‐office range, is an essential practice for the maintenance of high quality of service. The majority of the commonly available monitoring techniques carries high complexity and/or costs or is not suited to permanent fiber fault examination. In this article, it is proposed a novel low‐cost monitoring technique based on the back reflection of the Raman pump signal. We demonstrate, experimentally and recurring to Monte‐Carlo numerical simulation, that the histogram profile of the photodiode current produced by the reflected signal depends on the number of reflective events occurring in the intra‐office fiber section. © 2016 Wiley Periodicals, Inc.
