Description

一种波分复用光通信装置 技术领域
本发明涉及波分复用技术领域，尤其是指一种波分复用光通信装置。
 背景技术
波分复用(Wavelength Division Multiplexing，简称WDM)是将两种或多种不同波长且携带各种信息的光载波信号在发送端经复用器(亦称合波器，Multiplexer)汇合在一起，并耦合到光线路的同一根光纤中进行传输的技术；在接收端，经解复用器(亦称分波器或去复用器，Demultiplexer)将各种波长的光载波分离，然后由光接收机作进一步处理以恢复原信号。这种在同一根光纤中同时传输两个及以上不同波长光信号的技术，称为波分复用。
近几年来，由于传统的板载芯片封装技术（Chip On Board，简称COB）所采用的激光多为850nm的多模激光，且用并行光通信方法实现多路光并行通信，所以可在同一根光纤中同时传输两个及以上不同波长光信号的WDM技术被广泛应用于COB。目前，现有的应用于COB的WDM光通信装置分为短波长波分复用光通信装置和粗波长波分复用光通信装置，其中，短波长波分复用光通信装置借鉴了单模光纤的WDM技术，扩展了传输时所用的波长范围，从传统多模光纤所用的850nm扩展至850nm-1000nm，并利用性价比高的短波长的垂直腔面发射激光器(Vertical-Cavity Surface-Emitting Laser，简称VCSEL)和优化的宽带多模光纤(WBMMF)，在一根多模光纤上支持多个波长传输数据，大大降低了所需要的光纤芯数，同时又提高了光纤的有效模式带宽(Effective Modal Bandwidth，简称EMB)，延长了传输距离。然而，不管是短波长波分复用光通信装置，还是粗波长波分复用光通信装置，均不能对输出光功率的大小进行调节，大大限制了这些光通信装置的应用场景和范围。
因此，有必要对上述应用于COB的波分复用光通信装置进行改进。
 技术问题
本发明所要解决的技术问题是：提供一种波分复用光通信装置，旨在解决现有的应用于COB的波分复用光通信装置不能对输出光功率的大小进行调节的问题。
 技术解决方案

在一些具体的实施方案中，所述驱动组件为伺服电动机，所述显示屏为触控显示屏。
在一些具体的实施方案中，多个所述滤波片组成第一滤波片组，且该波分复用光通信装置还包括：多组第二滤波片组，任一所述第二滤波片组包括与第一滤波片组相同数量的滤波片，且任一所述第二滤波片组中的滤波片与第一滤波片组中的滤波片之间具有不同的波长。
在一些具体的实施方案中，所述第一滤波片组中的滤波片及任一第二滤波片组中的滤波片均与旋转轴可拆卸连接。

 有益效果
与现有技术相比，本发明的有益效果在于：
多个具有不同波长的光被多个光透镜准直后，先对应照射到多个滤波片上，再由多个滤波片将多个具有不同波长的光反射成平行的光后到达接收口汇聚成一束光。在此过程中，由于多个滤波片通过调节组件可相对于衍射光组件同步旋转预设范围的角度，所以可通过相对于衍射光组件同步旋转多个滤波片，使得多个滤波片与衍射光组件开设有安装孔一面的角度实时可调，达到了对输出光功率的大小进行实时调节的目的。

如图1、图2以及图3所示，本发明第一实施例提供的波分复用光通信装置包括衍射光组件1、调节组件（图中未示出）、接收口2、多个光透镜3及具有不同波长的多个滤波片4，其中，衍射光组件1上间隔开设有多个安装孔5，光透镜3设置在安装孔5内，调节组件位于衍射光组件1内且与衍射光组件1转动连接，多个滤波片4倾斜设于调节组件上，且每一滤波片4对应光透镜3的位置设置以遮挡经由光透镜3入射的光，接收口2设于衍射光组件1一端，且位于衍射光组件1的出射光路上，经多个光透镜3入射的光可分别由多个滤波片4反射后汇聚至接收口2，且调节组件用于带动多个滤波片4相对于衍射光组件1同步旋转预设范围的角度。
具体的，于实际工作过程中，多个具有不同波长的光被多个光透镜3准直后，先对应照射到多个滤波片4上，再由多个滤波片4将多个具有不同波长的光反射成平行的光后到达接收口2汇聚成一束光，以实现波分复用的合成，且在此过程中，滤波片4通过调节组件可相对于衍射光组件1同步旋转预设范围的角度。
具体的，本实施例提供的波分复用光通信装置既可以应用于短波长波分复用中，同时也可以应用于粗波分复用中。
需要说明的是，于其他实施例中，具有不同波长且集中在一根光纤上的光通过接收口2准直后依次照射在多个滤波片4上，再由多个滤波片4对应反射至多个光透镜3上，以此实现波分复用的解复用。
还需要说明的是，于其他实施例中，多个滤波片4是设置在多个光透镜3与接收口2之间的，故波分复用的合成和分解不是只能单独进行，即在多个光透镜3中，一部分光透镜3可作为波分复用合成时不同波长的光进入衍射光组件1使用，而另一部分光透镜3同时可作为波分复用分解时不同波长的光穿出衍射光组件1使用，同时接收口2亦可对应设置有多个。
本发明第一实施例提供的波分复用光通信装置，第一方面，多个具有不同波长的光被多个光透镜准直后，先对应照射到多个滤波片上，再由多个滤波片将多个具有不同波长的光反射成平行的光后到达接收口汇聚成一束光。在此过程中，由于多个滤波片通过调节组件可相对于衍射光组件同步旋转预设范围的角度，所以可通过相对于衍射光组件同步旋转多个滤波片，使得多个滤波片与衍射光组件开设有安装孔一面的角度实时可调，达到了对输出光功率的大小进行实时调节的目的。第二方面，在多个光透镜中，一部分光透镜可作为波分复用合成时不同波长的光进入衍射光组件使用，而另一部分光透镜同时可作为波分复用分解时不同波长的光穿出衍射光组件使用，同时接收口也可以对应设置有多个，使得该光通信装置可以适应多种工作情况，增大了该光通信装置的应用场景。
请参阅图4以及图5，图4为本发明第二实施例提供的衍射光组件的结构示意图，图5为本发明第二实施例提供的第二滤波片组的结构示意图。
以本发明第一实施例提供的波分复用光通信装置为基础，在本发明第二实施例中：
进一步地，如图4所示，调节组件包括多个旋转轴（图中未示出），衍射光组件1内设有多个放置槽6，且多个放置槽6位于多个安装孔5两侧，旋转轴架设在任意两个相对的放置槽6内并与衍射光组件1转动连接。
具体的，在旋转轴带动滤波片4向前或向后转动的过程中，滤波片4可分别抵接在放置槽6上。
可选的，于其他实施例中，可将滤波片4设置在旋转轴上，而旋转轴直接在衍射光组件1内与衍射光组件1转动连接，即不限于以放置槽6为中间载体。
进一步地，如图4所示，本实施例提供的波分复用光通信装置还包括显示屏7、控制组件8、驱动组件9及至少一传感器（图中未示出），其中，传感器设置在衍射光组件1的出射光路上，显示屏7、控制组件8及驱动组件9设置在衍射光组件1外壁上，传感器分别与显示屏7及控制组件8电连接，控制组件8分别与显示屏7及驱动组件9电连接，驱动组件9驱动连接于滤波片4与放置槽6之间的旋转轴。
进一步地，驱动组件9为伺服电动机，显示屏7为触控显示屏。
具体的，于实际工作过程中，通过触控显示屏7设置该波分复用光通信装置的输出光功率的预设值并发送给控制组件8，传感器获取并发送输出光功率的实际值至控制组件8及触控显示屏7，触控显示屏7实时显示该波分复用光通信装置当前的输出光功率的实际值，控制组件8根据输出光功率的实际值与输出光功率的预设值控制驱动组件9带动滤波片4与放置槽6之间的旋转轴旋转，使得多个滤波片4相对于衍射光组件1同步旋转，以对输出光功率的大小进行调节，直至输出光功率的实际值与输出光功率的预设值相等为止。
需要了解的是，控制组件8控制驱动组件9带动旋转轴旋转时，使得滤波片4与衍射光组件1开设有安装孔5一面的夹角在30°至60°之间可调。
可选的，于其他实施例中，显示屏7可不采用触控显示屏，可在衍射光组件1上设置多个按键（图中未示出）并与显示屏7电连接，此时，需要按动按键以设置该波分复用光通信装置的输出光功率的预设值。
进一步地，如图5所示，多个滤波片4组成第一滤波片组（图中未示出），且本实施例提供的波分复用光通信装置还包括多组第二滤波片组10，任一第二滤波片组10包括与第一滤波片组相同数量的滤波片，且任一第二滤波片组10中的滤波片与第一滤波片组中的滤波片之间具有不同的波长。
进一步地，第一滤波片组中的滤波片及任一第二滤波片组10中的滤波片均与旋转轴可拆卸连接。
具体的，于实际工作过程中，可根据该波分复用光通信装置的具体应用场景，根据第二滤波片组10内滤波片的波长，将多个滤波片4组成的第一滤波片组从衍射光组件1上替换下来。
进一步地，任意两个滤波片4之间的间隔为1mm。
可选的，于其他实施例中，任意两个滤波片4之间的间隔也不限于1mm，即可根据实际使用情况，调整任意两个滤波片4之间的间隔。
于本实施例中，滤波片4为二向色镜滤波片。
可选的，于其他实施例中滤波片4可为长波通滤波片、短波通滤波片、截止滤波片等滤波片中的任一种。
于本实施例中，接收口2为LC标准单模光纤接口。
可选的，于其他实施例中，接收口2可为FC、SC、ST等标准单模光纤接口中的任意一个。
进一步地，本实施例提供的波分复用光通信装置还包括多个用于发射不同波长的激光器（图中未示出），多个激光器位于光透镜3远离滤波片4一侧，且分别对应多个光透镜3设置以分别向多个光透镜3发射光。
具体的，于实际工作过程中，首先，多个激光器分别发出具有不同波长的光；其次，多个具有不同波长的光分别被多个光透镜3准直后，依次照射至多个滤波片4上；最后，多个具有不同波长的光分别经多个滤波片4反射成平行的光后到达接收口2汇聚成一束光。
于本实施例中，激光器为VCSEL。
本发明第二实施例提供的波分复用光通信装置，第一方面，通过滤波片与放置槽之间的旋转轴、传感器、显示屏、控制组件及驱动组件之间的相互配合，使得该波分复用光通信装置实现了对输出光功率的大小的智能化、自动化调整。第二方面，滤波片可拆卸设置在旋转轴上，方便对滤波片进行清洁、替换。第三方面，除第一滤波片组之外，还设置多个第二滤波片组，此时，可根据该波分复用光通信装置的具体应用场景，根据第二滤波片组内滤波片的波长，将多个滤波片组成的第一滤波片组从衍射光组件上替换下来，增大了该波分复用光通信装置的应用范围。第四方面，任意两个滤波片之间的间隔为1mm，使得该波分复用光通信装置在很小的范围区域内，实现多种波长的波分复用，大大减小了波分复用光通信装置的尺寸，提高了传输速率密度。第五方面，接收口采用LC、FC、SC及ST标准单模光纤接口中任一个，可以方便外接光路。第六方面，设置多个用于发射不同波长的激光器以提供多个不同波长的光，多个激光器发出的不同波长的光通过该波分复用光通信装置可实现波分复用的合成。第七方面，在旋转轴带动滤波片向前或向后转动的过程中，滤波片可分别抵接在放置槽上，对滤波片的旋转起到了很好的限位作用，有效地避免了滤波片与衍射光组件开设有安装孔一面的角度调节过大而引起的该波分复用光通信装置功能丧失的问题。
