Patent ID: 7965939

Claim:
A point-to-multipoint passive optical network (PON) system comprising: a. an Optical Line Terminal (OLT); b. a first RF Optical Transmitter; c. a first RF Optical Receiver; d. a first Wave-Division-Multiplexer (WDM) comprising a first upstream port, a second upstream port, a third upstream port, and at least one downstream port; e. an optical fiber connecting the first RF Optical Transmitter to the first upstream port of the first WDM; f. an optical fiber connecting the first RF Optical Receiver to the second upstream port of the first WDM; g. an optical fiber connecting the OLT to the third upstream port of the first WDM; h. an optical splitter with at least one upstream port and a plurality of downstream ports; i. an optical fiber connecting the downstream port of the first WDM to at least one upstream port of the optical splitter; j. one or more nodes, each node comprising: i. a first upstream port; ii. a second upstream port; iii. a downstream port; iv. a second RF optical transmitter comprising an upstream port and a downstream port; v. a second Wave-Division-Multiplexer (WDM) comprising a first upstream port, a second upstream port, and a downstream port; vi. an optical fiber connecting the first upstream port of the second WDM and the first upstream port of the node; vii. an optical fiber connecting the second upstream port of the second WDM and the second upstream port of the node; viii. an optical fiber connecting the downstream port of the second WDM to the upstream port of the second RF Optical Transmitter; and ix. an RF connection between the downstream port of the second RF Optical Transmitter and the downstream port of the node; k. an optical fiber connecting a downstream port of the optical splitter to the first upstream port of the node; l. at least one three-wave length ONU, comprising: i. an upstream port; and ii. a downstream port; m. an optical fiber connecting the second upstream port of the node to the upstream port of the ONU; and n. a diplexer, the diplexer connected to the downstream port of the ONU, the downstream port of the node, and an RF distribution network.
