摘要： A lens supporting frame is provided and includes a lens holder supporting a lens and a moving frame which is fitted to a cylindrical part of the lens holder to support the same. Ribs are provided at equal intervals in a rotation direction on a rear end face of the lens holder, the ribs having a plurality of inclined surfaces inclined respectively toward the front or rear ends of an optical axis. Abutting parts are provided on a rear end face of the moving frame so as to abut on the ribs. When the lens holder is rotated after mounting it in the moving frame, parts of the lens holder facing the abutting parts are moved in directions along the optical axis as a result of abutment between the inclined surfaces of the ribs and the abutting parts to change the inclination of the lens holder relative to the optical axis.

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 station-side apparatus adapted for use in a passive optical network (PON) system is disclosed, which remotely collects inside information of optical network terminals (ONTs) even before completion of start-up of an optical network unit (ONU), permits an obstruction-detected ONU to send out an emergency notification message to the station-side apparatus, e.g., optical line terminal (OLP), and permits the OLT that received this message to interrupt the transmission of an upload signal toward another ONU after the elapse of a fixed length of time while at the same time receiving information from the obstruction-suffering ONU to thereby facilitate cut-and-divide or “segmentation” of obstruction. A subscriber-side device for use in the PON system is also disclosed.

摘要： A session relay apparatus for preventing the packet relay delay by detecting the start and end of the policy settable peer-to-peer communication is disclosed. The session relay apparatus for relay a session control message transmitted and received between communication terminals to control the peer-to-peer communication detects the start and end of the communication from the session control message, and acquires the information for identifying a session and the information on the peer-to-peer communication carried out on the session. Upon generation of a policy indicating the packet relay control process by a policy generating unit, edge nodes for passing the packet are searched for and the policy is distributed to the edge nodes. The policy is set in the edge nodes accommodating the communication terminals at the start of communication, and the policy setting is canceled at the end of communication.
