A technique for automatic protection switching in conjunction with a capability for intercommunications between customers in a passive optical network is proposed and experimentally verified. Protection switching against fibre breaks is carried out using a secondary fibre that enables inter-customer networking using RF subcarrier multiplexed transmission along with the upstream transmission to the central office at baseband.

Inspec keywords: subcarrier multiplexing; optical switches; optical fibre LAN

Other keywords: automatic protection switching; LAN emulation; upstream transmission; passive optical networks; fibre breaking; inter-customer networking; RF subcarrier multiplexed transmission

Subjects: Multiplexing and switching in optical communication; Computer communications; Communication switching; Optical fibre networks
