Abstract

An ultra wideband adapter and a system including the ultra wideband adapter are disclosed. The ultra wideband adapter includes a first input to receive video from a passive optical network element, a second input to receive data from the passive optical network element, an ultra wideband modulator to modulate the received data, a diplexer to diplex the received video with the modulated ultra wideband data to provide a diplexed video, and an output to transmit the diplexed video.

Claims

1. A system comprising:

a first ultra wideband adapter comprising;

a first input to receive video from a passive optical network element;

a second input to receive data from the passive optical network element;

an ultra wideband modulator to modulate the received data to modulated ultra wideband data;

a diplexer to diplex the received video with the modulated ultra wideband data to provide a diplexed video; and

an output to transmit the diplexed video to a passive optical splitter, wherein the passive optical splitter comprises a first output and a second output, and wherein the second output is operable to transmit the diplexed video to a second ultra wideband adapter.

2. The system of claim 1, wherein the first ultra wideband adapter further comprises a bandpass filter to bandpass-filter the received video.

3. The system of claim 2, wherein the first ultra wideband adapter further comprises an amplifier to amplify the bandpass-filtered video.

4. The system of claim 3, wherein the first ultra wideband adapter further comprises a matched filter to match-filter the amplified bandpass-filtered video.

5. The system of claim 1, wherein the ultra wideband adapter further comprises a transceiver to receive the data.

6. The system of claim 1, wherein the modulated ultra wideband data is part of a noise floor of the diplexed video.

7. The system of claim 1, wherein the first output of the passive optical splitter is operable to transmit the diplexed video to a set top box (STB).

8. The system of claim 7, wherein the STB displays the diplexed video via a display device without interference from the ultra wideband modulated data.

9. The system of claim 7, wherein the second ultra wideband adapter detects the modulated ultra wideband data of the diplexed video and converts the detected modulated ultra wideband data into data for transmission to a computing device.

10. The system of claim 9, wherein the second ultra wideband adapter is further adapted to convert data from the computing device into ultra wideband data and is adapted to transmit the converted ultra wideband data via the passive optical splitter to the first ultra wideband adapter.

11. The system of claim 1, wherein the modulated ultra wideband data is position or amplitude modulated across a range of spectra extending from 1 GHz to 10 GHz.

12. An ultra wideband adapter comprising:

a first input to receive video from a passive optical network element;

a second input to receive data from the passive optical network element;

an ultra wideband modulator to modulate the received data to provide modulated ultra wideband data;

a diplexer to diplex the received video with the modulated ultra wideband data into a diplexed video; and

an output to transmit the diplexed video to a passive optical splitter, wherein the passive optical splitter comprises a first output to transmit the diplexed video to a set top box (STB) and a second output to transmit the diplexed video to a second ultra wideband adapter.

13. The ultra wideband adapter of claim 12, wherein the modulated ultra wideband data is part of a noise floor of the diplexed video.

14. The ultra wideband adapter of claim 12, wherein the modulated ultra wideband data is position or amplitude modulated across a range of spectra extending from 1 GHz to 10 GHz.

15. A method comprising:

receiving video at a first ultra wideband adapter from a passive optical network element;

receiving data from the passive optical network element;

modulating the received data to provide modulated ultra wideband data;

diplexing the received video with the modulated ultra wideband data to provide a diplexed video;

splitting the diplexed video at a passive optical splitter into a first diplexed video and a second diplexed video; and

transmitting the second diplexed video to a second ultra wideband adapter.

16. The method of claim 15, wherein diplexing the received video comprises diplexing the modulated ultra wideband data to a noise floor of the diplexed video wherein the noise floor does not interfere with a video component of the diplexed video.

17. The method of claim 15, further comprising:

transmitting the first diplexed video to a set top box (STB).

18. The method of claim 17, further comprising communicating the first diplexed video via the STB to a display device without interference from the modulated ultra wideband data.

19. The method of claim 17, further comprising:

detecting the modulated ultra wideband data of the diplexed video at the second ultra wideband adapter; and

converting the detected modulated ultra wideband data into data for transmission to a computing device.

20. The method of claim 19, further comprising:

receiving data from the computing device at the second ultra wideband adapter;

converting the data received from the computing device into ultra wideband data; and

transmitting the converted ultra wideband data, via the passive optical splitter, to the first ultra wideband adapter.
