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。

摘要： A transmission apparatus for use in fixed bandwidth communications and variable bandwidth communications. The transmission apparatus has a memory unit, which stores information contained in a frame and indicating the amount of data to be transmitted from a terminal device, a computing unit, which calculates a bandwidth amount to be assigned to the terminal device based on the data amount, and a transmission unit, which sends the calculated assigned bandwidth amount to the terminal device. The transmission apparatus is characterized in that the computing unit calculates bandwidth amounts to be assigned to different types of flow of which different transmission qualities are requested according to a priority level that is set to each flow type. The transmission apparatus is also characterized in that bandwidth is controlled by designating, instead of a necessary bandwidth amount, transmission starting timing and transmission ending timing, particularly for fixed bandwidth communication data.
