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： The variable displacement compressor has a suction-pressure region, a discharge-pressure region and a crank chamber. The compressor includes a supply passage, a bleed passage and a control valve that adjusts cross-sectional area of the bleed passage. The control valve includes a valve chamber, a valve portion and a valve seat member. The valve portion is disposed in the valve chamber for dividing the valve chamber into a bleed chamber, a backpressure chamber and a communication passage. The bleed chamber forms a part of the bleed passage. The backpressure chamber communicates with the supply passage. The communication passage is formed between an outer circumferential surface of the valve portion and an inner circumferential surface of the valve chamber for providing fluid communication between the bleed chamber and the backpressure chamber. The valve seat member is disposed in the bleed chamber and provided separately from a compressor housing forming the valve chamber.
