Abstract:
A WDMPON(Wavelength-Division-Multiplexed Passive Optical Network) is provided to use LEDs as a light source for optical communication by enabling a central office to have a pump means and enabling a remote node to has an amplifier, thereby realizing a high-quality optical communication service. A WDMPON comprises the followings: an ONU(Optical Network Unit)(400) for transceiving an optical communication service; a remote node(300) which has an amplifier(310) which amplifies a wavelength of light transmitted from the ONP(400); and a central office(100) which receives the amplified light. The central office(100) has a pump means(140) for amplifying the amplifier(310). The ONU(400) comprises LEDs(Light Emitting Diodes) as a light source from which the light is transmitted. The amplifier(310) has an isolator which amplifies only the light from the ONU(400) to the central office(100) and passes the amplified light.

Abstract:
PURPOSE: A rotary encoder and a control method thereof are provided to improve the reliability on the angle detection of multiple encoders. CONSTITUTION: A control method of a rotary encoder is as follows. Each predicted angle and real angle of multiple rotation angle detection members are obtained(302, 304). It determines the first rotation angle detection member that a predicted angle and a real angle are different. It determines the second rotation angle detection member having the real angle which is most similar as the predicted angle of the first rotation angle detection member. A count value of the second rotation angle detection member is reset as a new count value of the first rotation angle detection member(306). The first rotation angle detection member is recognized through the reset count value of the first rotation angle detection member.

Abstract:
A network bridge apparatus and a communication method using the same are provided to make it possible to offer a bridge function through search of services by devices positioned at an external cluster. A storage unit(102) stores first attribute information provided by first devices, that is, a DTV and a set-top box, which are included in a first cluster, for communication. An external communication unit(104) transmits the first attribute information stored to the storage unit to a second cluster. The external communication unit receives second attribute information provided by second devices, which are included in the second cluster, for communication. A controller(106) recognizes services provided from the second devices by analyzing the second attribute information received from the second cluster, and generates virtual devices corresponding to the second devices. The controller notifies that a new device is connected to the first devices in order to make the first devices recognize as if the virtual device is actually located in the first cluster.
