Abstract

An electromagnetic signal transport and distribution system and method provides for aggregating signals from multiple transport media and for distributing the signals to multiple end points in one or multiple formats to suit end user devices.

First claim

What is claimed is:

1. A signal transport and distribution system for users with satellite television and internet services:
a signal combining section coupled with a signal distribution section via one bidirectional single-mode optical fiber;
the signal combining section including a first multiplexer with coaxial cable and fiber inputs;
the coaxial cable inputs for interconnection with the facilities of three or more multimedia signal providers via at least three direct broadcast satellite (“DBS”) antennas, each antenna having at least one low noise block downconverter;
the fiber inputs for interconnection with facilities of an internet services provider via an optical line termination;
the signal path between the low noise block downconverters and respective multiplexer ports not exceeding a distance of 150 feet; and,
the signal distribution section including
a demultipelxer with plural coaxial outputs for recovering the mutimedia signals of the plural multimedia signal providers and a fiber output,
a second multiplexer for aggregating the coaxial outputs for transport on one aggregated signal coaxial cable for delivery of video signals to a television via a set top box,
an optical network unit interconnecting the fiber output and an Ethernet connection;
the Ethernet connection shared with the set top box and used by the set top box to send control signals to the first multiplexer; and,
bidirectional internet services provided via the Ethernet connection and satellite television services provided via the aggregated signal coaxial cable;
wherein single-mode optical fiber utilizes wavelengths including 1310 nm and three additional different wavelengths.

2. A signal transport and distribution system for users with satellite television and internet services:
an upstream signal transceiver and a plurality of signal transceivers downstream of the upstream signal transceiver;
each of the signal transceivers having a transfer port and a plurality of signal ports;
the upstream transceiver transfer port connected to a splitter via a single-mode optical fiber cable;
each downstream transceiver connected to the splitter via an optical fiber cable;
the downstream signal transceiver signal ports providing bidirectional transfer of three or more signals between the downstream transceiver and the splitter;
wherein a plurality of signals are multiplexed and distributed downstream by receiving signals at plural signal ports of the upstream transceiver, multiplexing the signals in the upstream transceiver, retransmitting the multiplexed signal from the upstream transceiver transfer port to the splitter, splitting the multiplexed signal for distribution to the downstream transceiver transfer ports, demultiplexing the multiplexed signals in the downstream transceiver, and transmitting the demultiplexed signals via the downstream transceiver signal ports to a SWM switch;
wherein a plurality of multiplexed signals are combined and transported upstream by receiving signals at plural signal ports of the downstream transceiver, multiplexing the signals in the downstream transceiver, retransmitting the multiplexed signals from the downstream transceiver transfer port to the splitter, combining the multiplexed signals from plural downstream transceivers in the splitter, forwarding the combined signals to the transfer port of the upstream transceiver, receiving and demultiplexing the multiplexed signals in the upstream transceiver, and transmitting the demultiplexed signals via the upstream transceiver signal ports; and,
wherein the single-mode optical fiber utilizes wavelengths including 1310 nm and three additional different wavelengths.

3. The system of claim 2 where the upstream transceiver and downstream transceiver have the same number and type of signal ports.

4. The system of claim 2 where the upstream and downstream transceivers each have signal ports to support radio frequency and optical signals.

5. The upstream transceiver of claim 2 having from three to six radio frequency signal ports and one optical signal port.

6. The downstream transceiver of claim 2 having from three to six radio frequency signal ports and one optical signal port.

7. The splitter of claim 2 capable of splitting the upstream multiplexed signal among one to sixty-four downstream transceivers.

8. The system of claim 2 adapted to receive six radio frequency signals and one optical signal from the upstream transceiver to each downstream transceiver, and one optical signal from each downstream transceiver to the upstream transceiver.

9. The system of claim 2 where the optical fiber is a single mode optical fiber.

10. The system of claim 2 where all optical components are passive.
