A scheme of monitoring a building or an apartment complex over WDM-PON is suggested. CDMA coding is used in transmitting sensor data from multiple ONTs to a receiver in the management center that is located near remote node.
Entire TDM-PON will get into a trouble even when only an ONU transmits optical signal constantly. This paper proposes a scheme to find the failed ONU. CDMA coding is used for the upstream transmission in failed situation.
