Abstract
This specification describes technologies relating to optical fiber network monitoring. A monitoring system is provided. The monitoring system includes a fiber network including a plurality of branch fibers and a main station coupled to a main fiber of the fiber network to broadcast communications signals to a plurality of branch stations. The monitoring system includes a monitoring device configured to transmit a monitoring signal and detect reflected portions of the monitoring signal such that the received portions specifically identify a condition of specific branch fibers of the plurality of branch fibers and a plurality of filtering devices coupled to each respective branch fiber, each filtering device including a transmission window configured to pass a plurality of communication wavelengths and a distinct wavelength of the monitoring signal, where the distinct wavelength is not within the transmission window, and block the remaining wavelengths, where the distinct wavelength identifies the respective branch fiber.
