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 . If we use only Ethernet switches, we can also protect the transmission path failure with the help of the link aggregation control protocol.
