摘要： The passive optical network includes a master station and slave stations connected via an optical fiber network including an optical splitter and a plurality of optical fibers. The master station includes a bandwidth control unit which decides a volume of a transmission signal to be granted to each slave station in every first period and in accordance with a request from the slave station, and a transmission timing control unit which decides, in one of a plurality of second periods and in accordance with the decided volume of the signal, transmission timing in which the slave station should transmit a signal. When the signal is to be transmitted by division over the plurality of second periods, the bandwidth control unit or the transmission timing control unit is controlled based on a volume of a signal to be attached by division processing, so that the granted signal can be transmitted in the first period.

摘要： In the case where, in a WDM-PON system, a high-output optical signal or a pseudo signal for illegal access by a hostile user, or an optical signal with a wavelength which is not assigned from an OLT is input to an ONU-side optical fiber, the quality of communications for other users is possibly affected and a receiver on the station side is possibly destroyed. By providing an optical blocking unit at a position near an ONU-side optical splitter of an optical branching unit, in the case where input of an extraordinary optical signal is detected, an optical route into which the extraordinary optical signal is input is blocked, so that the input of the extraordinary optical signal to an OLT and optical lines shared by plural users can be preliminarily blocked.

摘要： A passive optical network system (PON) has a plurality of OLTs and ONUs with different transmission rates. OLTs with different transmission rates share information of priority frames and destinations, and determine timing for frame transmission to ONUs so that the signal from each of the OLTs does not collide when multiplied in a splitter. OLTs transmit the data to the ONU as a burst signal to prevent the signals with different rates from colliding. ONU acquires the information of the following burst frames. ONU receives only the signal addressed to the own ONU or with the transmission rate of own ONU, therefore errors in ONUs can be avoided. OLT receives only the signal with the transmission rate of own OLT from ONUs based on the transmission timing from the ONUs shared by the line terminators, errors in OLTs can be avoided.

摘要翻译： 无源光网络系统（PON）具有多个具有不同传输速率的OLT和ONU。 具有不同传输速率的OLT共享优先级帧和目的地的信息，并确定向ONU发送帧的定时，使得来自每个OLT的信号在分离器中相乘时不会发生冲突。 OLT将数据作为突发信号发送到ONU，以防止具有不同速率的信号相互冲突。 ONU获取以下突发帧的信息。 ONU仅接收寻址到自己的ONU的信号或以自己的ONU的传输速率，因此可以避免ONU中的错误。 基于来自线路终端机共享的ONU的传输定时，OLT仅从ONU接收到自身OLT的传输速率的信号，可以避免OLT中的错误。

摘要： When a signal of weak optical power is received immediately after a signal of intense optical power, input of the signal of intense optical power readily causes saturation, and the influence interferes in the signal of weak optical power to deteriorate receiver sensitivity. Moreover, when a reverse-bias voltage of APD is changed, if a difference between the voltages is large, a next optical signal is received until the receiver sensitivity of the APD becomes stable, so that receiver sensitivity deteriorates. A DBA order is determined so that a difference in reverse-bias voltage is small, and reverse-bias voltage is controlled in line with reception timing from ONU.

摘要： A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view. A plasma display panel includes two spaced substrates defining a gap therebetween. The gap is divided by intersecting walls into columns and rows of discharge cells. Portions of a wall that are lower in height than remaining portions of the wall define a flow path. The plasma display panel realizes a bright and stable display.
