摘要： An optical access network method, an optical access network and an optical switch for an optical access network, capable of solving all the three problems in the conventional GE-PON: transmission distance problem, security problem and communication interference problem. The optical access network comprises an OLT, a plurality of ONUs and one or more stages of optical switches, which are connected one another. In the direction from the OLT to the ONU, each frame (packet) transmitted from the OLT to one of the ONUs is checked so that only the destination ONU specified in the frame (packet) is connected to the OLT. In the direction from the ONU to the OLT, a control message transmitted from the OLT to one of the ONUs is checked so that only one ONU which has been given a transmission allowance from the OLT is connected to the OLT with respect to each frame (packet).

摘要： The present invention is to provide an optical access network in which a remote unit receives an optical burst signal. A central unit (OLT) transmits a DC-balanced optical continuous signal including packets having identification information for identifying each remote unit (ONU) to an optical switching module (OSM). The optical switching module (OSM) receives the DC-balanced optical continuous signal from the central unit (OLT), optically switches the packets based on the identification information, and transmits a DC-balanced optical burst signal including the packets to the remote unit (ONU). The remote unit (ONU) receives the DC-balanced optical burst signal and acquires the packets transmitted to the remote unit (ONU).

摘要： In order to provide a guide roller which can be readily mounted on a support member and readily adjusted in position without reducing strength of a support shaft, according to the invention, when inserting a screw part of the shaft through a long hole of the support member and fixing the shaft by a nut on a back side, the screw part is inserted while contacting notched planes with contact parts, and an insertion position of the screw part is made adjustable in the long hole. It is possible, without necessity to form an engaging part for calking in the columnar shaped support shaft, to prevent reduction in strength of the guide roller, to position the guide roller with respect to a rail only by screwing the guide roller to the support member after previously fixing the support member to the slide door, and to make the operation efficient.

摘要： Inputted packets are sorted into flows and a minimum guaranteed transmission band is set up for each flow. When a back pressure signal for limiting a supply of packets to an output port is generated, in each flow containing the packets to be supplied to the output port, if the input rate of the packets contained in that flow is equal to or less than a rate corresponding to the minimum guaranteed transmission band set in the flow, the packets contained in the flow is supplied to the output port at the same output rate as the input rate, and otherwise, the packets contained in the flow is supplied to the output port at an output rate corresponding to the minimum guaranteed transmission band set in the flow.
