Self-protection against fiber fault for ring- based power-splitting passive optical networks

We propose and investigate a new ring-based power-splitting passive optical network PS-PON with a self-healing mechanism that prevents fiber fault. Using our proposed Y-type passive component with bidirectional func- tion in each remote node RN, the proposed ring-based PS- PON can be retrieved directly under single fiber failure. © 2008 Society of Photo-Optical Instrumentation Engineers.
