WAVELENGTH DIVISION MULTIPLEXING - PASSIVE OPTICAL NETWORK SYSTEM

摘要

PURPOSE: A passive optical scriber network system of a wavelength division multiplexing is provided to compensate a penalty by deterioration according a signal mode optical fiber transmission itself. CONSTITUTION: An OLT(Optical Line Terminal)(100) multiplexes the spectrum-divided light per wavelength after diving spectrum of the wideband non-interference light. The ONT(Optical Network Terminal)(200) receives an optical signal from the OLT. A remote node connects the OLT and the ONT. By using dispersion compensation fiber, a dispersion compensation module(170) compensates a relative intensity noise.
