Centralised Optical Monitoring of Tree-Structured Passive Optical Networks Using a Raman-Assisted Otdr

Monitoring of tree-structured Passive Optical Networks from a central office is difficult to achieve using a standard OTDR. Switchable reflective elements placed at the ONU can help to discriminate between the branches. In parallel, a Raman assisted OTDR is shown to increase the dynamic range of the reflectometry measurement, thus enabling to detect more faults in the network, and especially fibre breaks after the splitter. ©2007 IEEE.

Novel Monitoring Technique for Passive Optical Networks Based on Optical Frequency Domain Reflectometry and Fiber Bragg Gratings
(Institute of Electrical and Electronics Engineers Inc., 2010) Yüksel, Kıvılcım; Wuilpart, Marc; Moeyaert, Véronique; Mégret, Patrice
An efficient monitoring method having a very short measurement time (a few seconds) is proposed. The equal-length branches can be effectively monitored, but also the information of temperature at any place in the network can be obtained. The feasibility of this technique is experimentally demonstrated. © 2010 OSA.
