Highlights: [•] It uses the monitoring wavelength within the ITU-T U-band to implement PON in-service maintenance functions. [•] It provides a reliable and cost-effective approach to determine the faulty fiber branch among of the different fiber branches in TDM-PON. Furthermore, it can support the number of customers up to 256. [•] Combining with the OTDR can exactly determine the location of the fault. The OTDR is only placed in the CO instead of in the customer side, hence reduces the restoration time and the maintenance cost. [ABSTRACT FROM AUTHOR]
