WAVELENGHT DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK SYSTEM |
摘要 |
<p>The present invention relates to a Wavelength Division Multiplexing (WDM) Passive Optical Network (PON) system and a multi-ring type WDM PON system. The WDM PON system is implemented to appropriately compensate signals that are transmitted and received between an optical communication line and the multiplexer/demultiplexer of a Central Office (CO). A plurality of ring-type optical communication lines is employed in the WDM PON system. Accordingly, various types of loss caused by various environmental factors, such as insertion loss caused by interfacing a variety of devices with an optical communication line and loss caused by the degradation of an optical cable, are compensated for, thus improving the quality and stability of communication.</p> |
