Motivation and applications of the proposed hardware implementation of the Linearized Bregman Iteration algorithm. Depicted in a is the scenario where a centralized optical fiber network manager must deal with several links simultaneously, and being able to expedite the measurement is beneficial. DT TX, data transmission unit; PLM, physical layer monitoring unit. Depicted in b is the combination of a data acquisition hardware for the PLM (adapted from [10]) along with the data processing hardware implementation of the LBI algorithm. The optical pulse generation (PG) unit launches a probing pulse into the fiber, while the data acquisition system, together with an optical circulator and an optical pulse detection (PD), acquires the reflected optical power and produces a fiber profile
