Abstract:
1. A ring-connected optical network unit (ONU) for distributing signals, the ONU comprising: an optical port for transceiving optical signals; an optical-to-electrical translation module having an interface connected to the optical port, and an interface for transceiving electrical signals, the translation module converting multiplexed electrical signals into optical signals, and transmitting the optical signals; a first (North) ring port connected to the translation module for the ring-connected transceiving of electrical signals; a second (South) ring port connected to the translation module for the ring-connected transceiving of electrical signals; a plurality of customer interfaces, each transceiving electrical signals with a user; a first multiplexer having an interface connected to the ring ports and the customer interface to receive electrical signals, and an interface connected to the translation module to supply a multiplexed electrical signal; and, a second multiplexer having an interface connected to the ring ports and the customer interface to receive electrical signals, and an interface connected to supply multiplexed electrical signal to the first ring port; a third multiplexer having an interface connected to the ring ports and the customer interface to receive electrical signals, and an interface connected to supply multiplexed electrical signal to the second ring port; and, a framer module haying an interface to accent a plurality of customer interface electrical signals from a plurality of customer interfaces, and an interface connected to the first, second, and third multiplexers to supply the plurality of customer interface electrical signals framed into an ITU-T G.984.3 Gigabit-capable Passive Optical Network (GPON) signal.
