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： Communication time period measuring frames are simultaneously sent from an OAM adaptive device on a transmission side, to both a working path and a protection path. In an OAM adaptive device on a reception side, reception times of the frames having arrived from both the paths are checked so as to measure a time period difference between both the paths. The time period difference is fed back to a logic distance adjustment function of each PON section to determine required communication time periods of the PON sections respectively included in a working system and a protection system. Communication time periods of the working system and the protection system in a packet communication network are arbitrated in order to decrease a packet loss at line switching in a packet relaying network.

摘要： When data is disclosed to a plurality of users by using a transfer network and a transfer apparatus, data disclosure time control which cannot be adversely affected by the users is performed to reduce the difference in data disclosure time among the users. A transfer network system includes a distribution server serving as a data-distribution-source transfer apparatus, and a network terminal connected to distribution-destination user equipment. The distribution server and the network terminal each have a time keeping function and a time synchronization function for matching the time of the time keeping function with a master clock. The distribution server sends in advance disclosure data and disclosure time to the network terminal. When the time of the time keeping function of the network terminal matches the disclosure time, the network terminal sends the disclosure data to the user equipment.

摘要： An optical access system capable of avoiding cutoffs or interruption in the periodically transmitted signals that occur during the ranging time is provided. A first method to avoid signal cutoffs is to stop periodic transmit signals at the transmitter during the ranging period, and transmit all the periodic transmit signals together when the ranging ends, and buffer the signals at the receiver to prepare for ranging. A second method is to fix definite periods ahead of time for performing ranging, then cluster the multiple periodic transmit signals together in sets at the transmitter and send them, and then disassemble those sets back into signals at the receiver. The transmitting and receiving is then controlled so that the transmit periods do not overlap with the ranging periods. In this way an optical access system is provided that can send and receive signals requiring periodic transmissions without interruption even during ranging operation.
摘要翻译：提供一种能够避免在测距时间期间发生的周期性发射信号中的截断或中断的光接入系统。避免信号截止的第一种方法是在测距周期期间在发射机处停止周期性发射信号，并且在测距结束时将所有周期性发射信号传输到一起，并且在接收机处缓冲信号以准备测距。第二种方法是提前确定一段时间进行测距，然后将多个周期性发射信号集合在一起，并将其发送给发射机，然后将它们分组回接收机的信号。然后控制发送和接收，使得发送周期不与测距周期重叠。以这种方式，提供光接入系统，即使在测距操作期间也可以发送和接收需要周期性传输的信号而不中断。
