一种光线路终端、光网络单元及无源光网络系统技术方案

本发明专利技术实施例公开一种时分波分复用无源光网络TWDM‑PON系统，包括光线路终端OLT，光分配网络ODN，至少一个光网络单元ONU或光网络终端ONT，包括所述OLT包括一波长可调分波器，所述波长可调分波器具有一个公共端口和四个分支端口；所述OLT，用于控制所述波长可调分波器，使得所有从所述ONU或ONT发射并由所述波长可调分波器的公共端口进入的光信号全部解复用到所述四个分支端口中的第一端口，进入到与所述第一端口对应的第一接收机，关闭所述OLT的除第一接收机以外的其他接收机；所述OLT，还用于发送控制命令至所述ONU或ONT，所述控制命令用于指示所述ONU或ONT关闭其发射机的波长稳定装置；所述ONU，用于接收来自所述OLT的控制命令，关闭发射机的波长稳定装置。

Optical line terminal, optical network unit and passive optical network system

The embodiment of the invention discloses a time-division WDM passive optical network TWDM PON system, including OLT optical line terminal, optical distribution network ODN, at least one of the optical network unit ONU or optical network terminal ONT, including the OLT includes a wavelength adjustable filter, the wavelength tunable wave splitter have a common port and four port branch; the OLT, which is used to control the wavelength tunable splitter, so that all from the ONU or ONT emission and optical signal by the wavelength tunable public port WDM access all demultiplexing to the first port of the four port branch the first receiver into correspondence with the first port, close the OLT in addition to the first receiver other than the receiver; the OLT is also used to send control commands to the ONU or ONT, the control command is used for indicating the ONU or O The NT is used to close the wavelength stabilization device of the transmitter, and the ONU is used to receive the control command from the OLT, and the wavelength stabilization device is turned off.
