Abstract
A passive optical network includes: a central office for generating multiplexed downstream optical signals and receiving an upstream optical signal; a plurality of optical network units for receiving a corresponding downstream optical signal and generating subcarrier channels carrying electrical data of an assigned frequency; and a remote node for photoelectrically converting the channels into electrical data, electro-optically converting the electrical data into at least one upstream optical signal.

- a plurality of optical network units for receiving corresponding downstream optical signals and for generating subcarrier channels carrying electrical data of an assigned frequency;
- and
- a remote node for photoelectrically converting the channels into electrical data and for electro-optically converting the electrical data into at least one upstream optical signal.
A passive optical network comprising:
- a central office for generating multiplexed downstream optical signals and for receiving upstream optical signals;
- a remote node for splitting the downstream optical signals according to intensities and for outputting upstream optical signals to the central office;
- a plurality of optical network units for receiving downstream optical signals and for generating subcarrier channels carrying electrical data of an assigned frequency;
- and
- a converter for photoelectrically converting the channels into electrical data, for electro-optically converting the electrical data into at least one upstream optical signal with an equal wavelength to output the converted upstream optical signal to the remote node, and for splitting the downstream optical signals, which are split by the remote node according to intensities, based on intensities to output the split downstream optical signals to a corresponding linked optical network unit.
