摘要： An Optical Line Terminal (OLT) configuring a Passive Optical Network (PON) is provided. The OLT includes an optical transmitter that transmits an optical signal to Optical Network Units (ONUs) in a downstream direction, an optical receiver that includes general Continuous Mode (CM) signal processing elements to recover clocks and data from optical signals transmitted by ONUs in an upstream direction, and a controller that controls the ONUs such that the optical receiver continuously receives an optical signal. An OLT interface for receiving an optical signal can be implemented using the general CM signal processing elements.

摘要： A burst mode optical repeater is provided. The burst mode optical repeater receives optical signals, which are transmitted from a plurality of optical network units (ONUs) in a passive optical network (PON) to a central office using a time division multiplexing access (TDMA) method, and relays the received optical signals using an optical-electrical-optical (OEO) method. Since the burst mode optical repeater can be installed anywhere between an optical line terminal (OLT) and the ONUs, the number of subscribers and transmission range that can be supported by a corresponding network can be increased.

摘要： Provided is an optical filtering apparatus which is applied to a Time Division Multiplexing Passive Optical Network (TDM-PON) based on a wavelength division multiplexing (WDM) method. The optical filtering apparatus includes: an optical signal distributing unit dividing an optical signal received from an optical line terminal into at least one optical signal with uniform output intensity, and distributing the at least one optical signal into at least one optical network unit; and a multiplexing unit combining a plurality of optical signals having different wavelengths received from the at least one optical network unit using a wavelength division multiplexing (WDM) method, and outputting the combined optical signal to the optical line terminal. Therefore, by using the optical filtering apparatus, it is possible to connect a large number of subscribers to an Optical Line Terminal (OLT) on a network such as Fiber To The Home (FTTH), thereby increasing efficiency in costs.

摘要： Disclosed are a multiple passive optical network system and a wavelength splitter/combiner used in the same. The multiple passive optical network (PON) system includes a first PON, and a second PON which provides a service different in speed and capacity from the first PON while partially sharing network resources with the first PON. Thereby a subscriber can receive service through a network having a desired capacity and speed.
