Abstract
A passive optical network using downstream and upstream optical signals for achieving a two-way communication is provided, wherein the downstream and upstream optical signals have different polarization components and an equal wavelength band.
Claims19
A passive optical network using a downstream optical signal and an upstream optical signal for a two-way communication, wherein the downstream optical signal and the upstream optical signal have different polarization components and an equal wavelength band.
A passive optical network comprising:
- a central office for generating downstream optical signals having a first polarization component and demultiplexing upstream optical signals;
- a plurality of optical network units for generating the upstream optical signals having a second polarization component and detecting the demultiplexed downstream optical signals;
- and
- a remote node for multiplexing the upstream optical signals from the optical network units to the central office and demultiplexing the downstream optical signals from the central office to corresponding optical network units, wherein the downstream optical signals and the upstream optical signals have an equal wavelength band.

A passive optical network comprising:
- a central office for generating wavelength-locked downstream optical signals and for demultiplexing upstream optical signals;
- a plurality of optical network units for generating the upstream optical signals having a polarization component different from the downstream optical signals using a wavelength locking scheme and for detecting the downstream optical signals;
- and
- a remote node for multiplexing the upstream optical signals to the central office and for demultiplexing the down optical signals multiplexed by the central office to the corresponding optical network units, wherein the downstream optical signals and the upstream optical signals have an equal wavelength band.
