| 摘要 |
<p>The present invention relates to an optical network including a bridge (200) for selectively transferring information form an optical channel carried on a first WDM optical waveguide (20) to at least two optical channels on a second WDM optical waveguide (120). The first and second optical waveguides carry WDM optical signals each having plural waveguides which includes an optical add-drop multiplexer (320, 320', 340, 340') optically communicating with each waveguide. At least one optical channel having first and second data bits streams is dropped from the first waveguide. The first and second data bit streams are respectively encoded on two different optical channels which are then added to the second optical waveguide.</p> |
