Abstract

We propose and demonstrate a self-restorable wavelength-division-multiplexing passive optical network (WDM-PON) with a color-free optical source. When the distribution and feeder fiber links are broken, we can successfully recover the network by using optical switches and/or Ethernet switches. If the fault monitors detect the failures, optical switches change the transmission path and the failures are recovered within 10ms. If we use only Ethernet switches, we can also protect the transmission path failure with the help of the link aggregation control protocol.
