摘要： A passive optical network system includes: a plurality of optical signal splitter receiving optical signals from a plurality of optical network units (ONUs) to provide a plurality of upstream optical signals having different wavelengths; a hybrid optical filter multiplexing the plurality of upstream optical signals in a wavelength division multiplexing (WDM) scheme; and an optical line terminal (OLT) receiving the multiplexed upstream optical signals in a time division multiplexing (TDM) scheme. Therefore, the network system can be easily expanded when the number of subscribers increases, and the optical loss can be minimized.

摘要： A method and apparatus for duplex protection switching by using a single splitter in a passive optical network (PON) are provided. The apparatus for duplex protection switching in a PON, in which a single optical line termination (OLT) and many optical network terminations (ONTs) are connected together in a multiple-access manner, includes: a 2:2 splitter connected to two PON line terminations (LTs) in the OLT; and two N:1 splitters which are connected to the 2:2 splitter, and each of which is connected to two PON LTs in the ONT. According to the method and apparatus, an economical effect can be provided in which two links, an operational link and a protection link, in the PON can provide a partial duplex function at a lower cost. Also, a protection switching time can be reduced by simplifying a restoration process so that when an error is detected, an operational state is returned by protection switching.
