| 摘要 |
A wavelength division multiplexing passive optical network system is disclosed. The system includes a fiber transfer end for transmitting downstream optical signals through a fiber. The downstream optical signals are obtained by performing wavelength division multiplexing on downstream channels having different wavelengths from one another. The fiber transfer end also demultiplexes upstream optical signals received through the fiber. The upstream optical signals are include a first and a second upstream channels having different wavelengths from one another. The system also includes a power splitter for performing a uniform power split on the downstream optical signals received through a first port that is connected to the fiber, and for outputting the split optical signals through a plurality of second ports, and for outputting upstream optical signals through the first port. The upstream optical signals are a combination of the first and the second upstream channels received from the plurality of second ports. The system also includes a plurality of optical network elements for demultiplexing the downstream optical signals from a second port of an optical divider by wavelengths, and for transmitting the first and the second upstream channels to the optical divider.
