Definitions

  • This disclosure relates to the field of optical communication technology, and in particular to a communication device.
  • Communication equipment such as cabinet-type or frame-type communication equipment, structurally includes a cabinet, a backplane (such as a printed circuit board backplane, active cable backplane, and fiber optic backplane), and multiple individual boards.
  • the cabinet has multiple slots, and the backplane is generally located at the back of the cabinet, serving as the bottom of the slots.
  • the individual boards are inserted into the slots, connecting to the backplane when fully inserted. For example, if the connection between the individual board and the fiber optic backplane is optical, then the fiber optic individual board has an optical interface, and the fiber optic backplane also has optical interfaces at the corresponding slot positions. When the individual board is fully inserted into the slot, the optical interface of the individual board mates with the optical interface of the fiber optic backplane to achieve a physical connection of the optical channel.
  • the optical interface (the optical interface of the fiber optic backplane) corresponding to the slot (referred to as the idle slot) is exposed.
  • the airflow for heat dissipation of the board can easily bring dust through the backplane, causing a large amount of dust to accumulate on the optical interface of the fiber optic backplane.
  • dust adheres to the optical coupling surface it will cause the optical signal quality to be attenuated, resulting in bit errors or even interruption of the optical link.
  • This disclosure provides a communication device in which the fiber optic backplane is located in a cabinet and its position is adjacent to the slot opening. Therefore, the airflow entering through the slot opening will not pass through the fiber optic backplane as it flows towards the bottom of the slot. Consequently, the airflow is less likely to carry dust to the first optical interface of the fiber optic backplane and its vicinity, which is beneficial for dust prevention of the fiber optic backplane and thus helps to ensure the optical communication quality of the communication device.
  • the cabinet has multiple slots along the height direction, and the fiber optic backplane has multiple sets of first optical interfaces along the height direction.
  • the fiber optic backplane stands in the cabinet, and the position of the fiber optic backplane is adjacent to the position of the slot opening. Each set of first optical interfaces of the fiber optic backplane corresponds to one slot of the cabinet.

Therefore, the airflow flowing between the slot opening and the bottom of the slot flows parallel to the fiber optic backplane instead of passing through it. As a result, the airflow is less likely to carry dust to the first optical interface of the fiber optic backplane and its vicinity, which is beneficial for dust prevention of the first optical interface of the fiber optic backplane and thus helps to ensure good optical communication quality.
  • the partition has multiple rotatable baffles along the height direction, and the multiple rotatable baffles are positioned opposite to the multiple slots;

  • the partition Since the fiber optic backplane needs to be connected to the single board inserted in the slot, the partition has an opening and closing function.

  • each of the plurality of boards has a dustproof frame surrounding the second optical interface, the side of the dustproof frame away from the board body portion having an opening through which the second optical interface is exposed.
  • the slot and the corresponding set of first optical interfaces are isolated by a rotatable baffle in a closed state, achieving physical isolation between the air duct and the first optical interfaces.
  • the dustproof frame of the board surrounds the set of first optical interfaces, achieving physical isolation between the air duct and the first optical interfaces.
  • the air duct passing through each slot is isolated from each set of first optical interfaces on the fiber optic backplane, thereby enhancing the dustproof effect of the fiber optic backplane and making the first optical interfaces of the fiber optic backplane less susceptible to dust contamination.

Description

通信设备
本公开要求于2024年05月27日提交的申请号为202410669152.4、发明名称为“通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本公开中。
技术领域
本公开涉及光通信技术领域，特别涉及一种通信设备。
背景技术
通信设备，如柜式通信设备或框式通信设备，在结构上包括机柜、背板(如包括印刷电路板背板、有源电缆背板和光纤背板等)和多个单板，机柜具有多个槽位，背板一般位于机柜的背面，作为多个槽位的槽底，单板插在槽位中，插到位时，与背板连接。例如，单板与光纤背板之间是光连接，那么，光纤单板具有光接口，光纤背板在对应各个槽位位置处，也具有光接口，当单板在槽位中插到位时，单板的光接口与光纤背板的光接口对接以实现光通道的物理连接。
在槽位未插有单板的情况下，该槽位(记为空闲槽位)所对应的光接口(是光纤背板的光接口)暴露在外，而为单板散热的气流，在穿过背板中，很容易带来灰尘，使光纤背板上的光接口聚积大量灰尘，当灰尘附着在光耦合面时会导致光信号质量衰减，从而导致光链路有误码甚至中断。
发明内容
本公开提供了一种通信设备，该通信设备的光纤背板在机柜中，其位置与槽位的槽口位置邻近，那么，槽口进入的气流，在流向槽底的过程中，气流不会穿过光纤背板，进而，气流不易将灰尘带向光纤背板的第一光接口及其附近，从而有利于光纤背板的防尘，进而有利于确保通信设备的光通信质量。
本公开提供了一种通信设备，所述通信设备包括机柜、光纤背板和多个单板；
所述机柜在沿着高度方向上具有多个槽位，所述光纤背板在沿着高度方向上具有多组第一光接口，所述光纤背板立在所述机柜中，且所述光纤背板所在位置与所述槽位的槽口所在位置相邻，所述光纤背板的一组第一光接口与所述机柜的一个槽位一一对应；
所述多个单板中的每个单板具有一组第二光接口，每个单板位于一个槽位中，且所述单板的一组第二光接口与所在槽位对应的一组第一光接口连接。
其中，槽位的槽口作为散热气流(简称气流)的入口，槽位的槽底作为气流的出口，那么，槽位的槽口和槽位之间形成气流的风道。
在本公开所示的方案中，该通信设备的光纤背板在机柜中的位置，邻近槽位的槽口所在位置，而不是位于槽底处，与槽口位置相对，那么，在槽口和槽底之间流通的气流，平行于光纤背板流通，而不是穿过光纤背板，所以，气流在风道中流通中，不易将灰尘带向光纤背板的第一光接口及其附近，有利于光纤背板的第一光接口防尘，进而有利于确保光通信质量良好。
在一种可能的实现方式中，所述机柜包括隔板，所述隔板立在所述多个槽位和所述光纤背板之间，且平行于所述光纤背板；
所述隔板在沿着高度方向上具有多个可旋转挡板，所述多个可旋转挡板与所述多个槽位一一位置相对；
对于所述多个可旋转挡板中的任意一个可旋转挡板，在所对应的槽位内的单板与所述光纤背板连接的情况下，处于旋开状态，在所对应的槽位为空闲槽位的情况下，处于关闭状态。
在本公开所示的方案中，隔板将多个槽位所在空间，与多组第一光接口所在空间隔开，那么，气流在空闲槽位中流通，不会窜入第一光接口所在空间，进一步有利于第一光接口的防尘。
由于光纤背板与插入槽位中的单板需要连接，所以，隔板具有打开和关闭功能，那么，当槽位为空闲槽位时，隔板在空闲槽位对应的位置处处于关闭状态，当槽位插有单板，且单板需要与光纤背板连接时，隔板在该槽位对应的位置处处于打开状态。
在本公开所示的方案中，隔板在沿着高度方向上具有多个可旋转挡板，其中可旋转挡板的数量与槽位的数量相同，且隔板位于机柜中，可旋转挡板与槽位一一位置相对。对于多个可旋转挡板中的任意一个可旋转挡板，在所对应的槽位内的单板需要与光纤背板连接的情况下，该可旋转挡板处于旋开状态，而在所对应的槽位为空闲槽位的情况下，该可旋转挡板处于关闭状态。
这样，空闲槽位与对应的一组第一光接口之间，有处于关闭状态的可旋转挡板物理隔开，进一步避免散热的气流，将灰尘带入第一光接口附近，有利于光纤背板的第一光接口防尘。
在一种可能的实现方式中，所述多个单板中的每个单板具有包围所述第二光接口的防尘框，所述防尘框的远离所述单板本体部分的一侧具有敞口，所述第二光接口通过所述防尘框的敞口外露。
在本公开所示的方案中，槽位中未插有单板的情况下，或者，槽位中插有单板，但是单板与对应的一组第一光接口连接之前，该槽位与所对应的一组第一光接口之间，通过处于关闭状态的可旋转挡板隔离，实现风道与第一光接口之间的物理隔离。而在槽位中插有单板，且单板的第二光接口与所对应的一组第一光接口连接的情况下，该单板的防尘框将该组第一光接口包围起来，实现风道与第一光接口之间的物理隔离。可见，无论单板是否插入槽位中，穿过各个槽位的风道，与光纤背板的各组第一光接口之间都处于隔离状态，从而增强光纤背板的防尘效果，使光纤背板的第一光接口不易受灰尘污染。
在一种可能的实现方式中，每个单板位于一个槽位中，且可在所在槽位中向靠近和远离所述光纤背板的方向滑行。
在本公开所示的方案中，单板插入槽位中并且插到位以后，再向单板施加侧向作用力，便能促使单板在槽位中，向靠近光纤背板的方向滑行，以实现单板与光纤背板的连接。而当需要将单板从槽位中拔出时，首先向单板施加反向作用力(与上述侧向作用力方向相反)，使单板在槽位中向远离光纤背板的方向滑行，以实现单板与光纤背板脱离连接，之后再将单板从槽位中拔出。
在一种可能的实现方式中，所述光纤背板的每一组第一光接口在所述机柜中，可向靠近和远离所对应的一个槽位的方向滑行。
在本公开所示的方案中，单板插入槽位中并且插到位以后，向所对应的一组第一光接口施加侧向作用力，便能促使该组第一光接口，向靠近单板的方向滑行，以实现单板与光纤背板的连接。而当需要将单板从槽位中拔出时，首先向所对应的一组第一光接口施加反向作用力，使该组第一光接口向远离单板的方向滑行，以实现单板与光纤背板脱离连接，之后再将单板从槽位中拔出。
在一种可能的实现方式中，所述光纤背板包括背板本体和多个托板，每一组第一光接口布置在一个托板上，且与所述背板本体之间通过跳纤连接；
所述背板本体固定在所述机柜中，每个托板在所述机柜中，可向靠近和远离所对应的一个槽位的方向滑行，其中，所述跳纤的长度大于所述托板的最大滑行行程。
在本公开所示的方案中，每一组第一光接口固定在一个托板上，这样便可以通过控制各个托板在机柜中左右滑行，而实现各组第一光接口在机柜中左右滑行。
在一种可能的实现方式中，每个单板具有多个第一定位结构，所述光纤背板具有多个第二定位结构；
所述多个第一定位结构和所述多个第二定位结构一一匹配，用于引导所述单板的第二光接口和所述光纤背板的第一光接口连接。
在本公开所示的方案中，在单板向靠近所对应的一组第一光接口滑行中，或者，在第一光接口向靠近所对应的单板滑行中，首先第一定位结构和第二定位结构先配合，第一定位结构和第二定位结构一一匹配以后，当单板滑到底或者当第一光接口滑到底时，便能实现单板与光纤背板的精准对准。
在一种可能的实现方式中，所述通信设备还包括电连接背板，所述电连接背板位于所述机柜中，且所述电连接背板与所述光纤背板位于所述多个槽位的同一侧；
每个单板还具有电接口，所述电接口和所述第二光接口位于所述单板的同一侧，每个单板位于一个槽位中，且所述单板的电接口与所述电连接背板连接。
在本公开所示的方案中，电连接背板与光纤背板位于槽位的同一侧，插入槽位中的单板与光纤背板连接的同时，单板与电连接背板也会连接。
在一种可能的实现方式中，所述通信设备还包括电连接背板，所述电连接背板位于所述机柜中，且在所述槽位的槽底位置处；
每个单板还具有电接口，所述电接口和所述第二光接口位于所述单板的不同侧，每个单板(3)位于一个槽位中，且所述单板的电接口与所述电连接背板连接。
在本公开所示的方案中，电连接背板位于槽位的槽底位置处，在单板插入到槽位中，且插到位时，单板与电连接背板完成电连接，而后单板在槽位中滑行，或者第一光接口在机柜中滑行，以实现单板与光纤背板的光对接。
在一种可能的实现方式中，所述通信设备还包括散热装置，所述散热装置位于所述机柜中，且在所述槽位的槽底位置处。
在本公开所示的方案中，散热装置布置在机柜的靠近槽位槽底位置处，这样，槽位的槽口位置为机柜的进风口，而槽位的槽底位置处机柜的出风口，使机柜在槽位的槽口和槽底之间形成气流流通的风道。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
本实施例涉及到一种通信设备，具体涉及到一种柜式或框式的光通信设备，如图1所示，为光通信设备的整体架构示意图，参考图1所示，通信设备包括机柜1、光纤背板2和多个单板3，机柜1的形状呈柜状或框状，在沿着高度方向具有多个槽位11，光纤背板2位于机柜1中，且在槽位11的槽底位置处，单板3可插拔位于槽位11中，例如，单板3由槽口插入，插到位时，与光纤背板2连接，如单板3插到位时，单板3的光接口与光纤背板2的光接口对接。
继续参考图1所示，通信设备的散热装置布置在光纤背板2和机柜1的背侧之间，那么，机柜1的槽口所在位置为通信设备的风道的进风口，机柜1的背侧为风道的出风口，光纤背板2位于风道上，如图1所示的箭头表示气流的流通方向。
继续参考图1所示，在某一个槽位11未插有单板3的情况下，该槽位11为空闲槽位，那么，光纤背板2的对应空闲槽位的光接口，会暴露在外，其光耦合面会受到灰尘污染，再加上，光纤背板2的暴露在外的光接口位于风道上，那么，气流流经暴露在外的光接口时，会进一步将灰尘带入该光接口的光耦合面上。而一旦光接口的光耦合面受到污染，那么在后续使用中，会造成光信号衰减较为严重，从而影响光链路的通信质量(如有误码情况)，甚至导致光链路通信中断。
再者，在某一个槽位11插有单板3的情况下，也存在气流可能会将灰尘吹进光纤背板的光接口内部，导致光耦合面受到污染。又或者灰尘积落到光纤背板的光接口附近位置，如连接器或光纤上，那么在单板拔出或下次插入中，产生大量扬灰后极易进入到光耦合面上。
因此，参考图1所示的方案，不管槽位11是否空闲，都有可能存在灰尘污染光纤背板的光耦合面的情况。
而且，参考图1所示，光纤背板2在机柜1中的位置较深，位于靠近机柜1的背侧位置处，工作人员也难以对光纤背板2上的光接口进行清洁处理。
因此，如图1所示的通信设备，在长时间工作以后，光纤背板2的光接口很容易因受灰尘污染，而降低光链路的通信质量。
本实施例提供了一种通信设备，该通信设备的风道不经过光纤背板，能够减弱光纤背板的光接口的污染程度，从而确保光通信质量。进一步，通信设备的风道与光纤背板之间有物理隔离，能够进一步减弱光纤背板的光接口的污染程度，进一步确保光通信质量。
如图2所示，为本实施例所提供的通信设备的架构示意图，参考图2所示，通信设备也是包括机柜1、光纤背板2和多个单板3，机柜1在沿着高度方向上具有多个槽位11，光纤背板2在沿着高度方向上具有多组光接口(为了区分于单板3的光接口，记为第一光接口21)，其中，每一组第一光接口21可以包括一个或多个第一光接口21。
继续参考图2所示，光纤背板2立在机柜1中，而且，光纤背板2在机柜1中的位置与槽位11的槽口所在位置相邻，而不是位置相对。例如，参考图2所示，光纤背板2是位于机柜1的左侧或者右侧，而槽位11的槽口位于机柜1的前侧。
继续参考图2所示，光纤背板2的每一组第一光接口21与一个槽位11位置相对，也即是，光纤背板2在对应每一个槽位11的位置处，都布置一组第一光接口21，以便于插入到槽位11中的单板3与光纤背板2实现光对接。
参考图2所示，从槽位11的槽口进入的气流，在流向槽底的过程中，是平行于光纤背板2，而不是穿过光纤背板2，从而，气流在槽口和槽底之间流通中，不易将灰尘带向光纤背板2的第一光接口21及其附近，光纤背板2的第一光接口21便不容易受到灰尘的影响，从而减弱光纤背板的第一光接口的污染程度。
在一种示例中，单板3可插拔位于槽位11中，例如，单板3能从槽位11的槽口处向槽底的方向插入，单板3也能从槽位11中拔出。
如图3所示为单板3的结构示意图，参考图3所示，单板3的一侧(记为第一侧)具有一组第二光接口31，其中，单板3的第一侧为邻近单板3面板的一侧。其中，一组第二光接口31中包括一个或多个第二光接口31，一般，一组第二光接口31所包括的第二光接口31的数量，与一组第一光接口21所包括的第一光接口21数量相同。这样，当单板3插入槽位11中，与光纤背板2连接时，单板3的一组第二光接口31与光纤背板2的一组第一光接口21一一对应连接。
不同于现有技术中光纤背板2位置与槽位11的槽口位置相对，布置在槽位11的槽底位置处，当单板3插到位即实现与光纤背板2连接，本实施例中，因为光纤背板2在机柜1中的位置与槽位11的槽口在机柜1中的位置相邻，那么，为了使插入到槽位11中的单板3能够与光纤背板2可插拔连接，一种方式可以是，插入到槽位11中的单板3能够横向左右滑行(参考图4和图5所示)，以实现槽位11中的单板3与光纤背板2连接或断开连接。另一种方式可以是，各组第一光接口21能够在机柜1中横向左右滑行，以实现槽位11中的单板3与光纤背板2连接或断开连接。另一种方式还可以是，机柜1的远离光纤背板2的侧板可拆卸，插拔单板3中需要将机柜1的侧板拆卸下来，以便于将单板3推向光纤背板2处与光纤背板2连接，或者断开单板3与光纤背板2的连接。
例如，作为一种示例，如图4并参考图5所示，每个单板3可在槽位11中横向滑行，能够向靠近所在槽位11对应的一组第一光接口21的方向滑行，也能向远离所在槽位11对应的一组第一光接口21的方向滑行。
在一种示例中，单板3在槽位11中左右横向滑行的实现方式可以是，各个槽位11中具有导轨，导轨与单板3的插拔方向垂直，各个单板3具有与导轨配合的滑轨或滑块，当单板3插入槽位11中且插到位以后，该单板3的滑轨或滑块位于槽位11的导轨中，从而向单板3施加横向作用力，便能使单板3在槽位11中横向滑行。
这样，工作人员或机械手持单板3的拉手条，将单板3由槽位11的槽口推入到槽位11中，插到位以后，再向单板3施加朝向光纤背板2的横向作用力，使单板3向靠近光纤背板2的方向平移，当平移到底时，单板3的一组第二光接口31与所在槽位11对应的一组第一光接口21一一连接。而当需要将单板3从槽位11中拔出时，工作人员或机械手持单板3的拉手条，首先向单板3施加远离光纤背板2的横向作用力，当单板3的第二光接口31与光纤背板2的第一光接口21脱离对接以后，再将单板3从槽位11中拔出。
又例如，作为另一种示例，单板3在槽位11中不可滑行，但是光纤背板2的每一组第一光接口21在机柜1中可向靠近所对应的槽位11的方向滑行，也可向远离所对应的槽位11的方向滑行。
需要指出的是，各组第一光接口21在机柜1中相互独立滑行，互不干扰，例如，需要某一组第一光接口21滑行时，与其邻近的其他组第一光接口21可以不滑行。
在一种示例中，为了使每一组第一光接口21都可以左右横向滑行，相应的，如图6所示，为通信设备的结构示意图，参考图6所示，光纤背板2包括背板本体20和多个托板22，托板22的数量与槽位11的数量相同，托板22和槽位11一一位置相对，每一组第一光接口21布置在一个托板22上，且每一组第一光接口21与背板本体20之间通过跳纤连接，其中，跳纤是一种位于机柜内部的光纤。
如图7和图8所示，背板本体20固定位于机柜1中，而每个托板22可向靠近所对应的槽位11的方向滑行，也可向远离所对应的槽位11的方向滑行，以便于托板22上的一组第一光接口21与该托板22所对应的槽位11中的单板3的一组第二光接口31可插拔连接。
其中，为了使第一光接口21与背板本体20之间的跳纤不干涉托板22的滑行，相应的，跳纤的长度大于托板22的最大滑行行程，最大滑行行程是最大的单向滑行行程。
在一种示例中，为了方便向各个托板22施加横向作用力，相应的，各个托板22也可以具有拉手条，这样，当某一个单板3插入到某一个槽位11中且插到位以后，机械手或工作人员持所对应的托板22的拉手条，向靠近该单板3的方向滑行，当托板22滑行到底时，该单板3的一组第二光接口31与布置在该托板22上的一组第一光接口21对接。
需要指出的是，每一组第一光接口21与所在托板22之间是固定连接，以便于第一光接口21跟着所在托板22滑行，且滑到底以后，能与单板3的第二光接口31对接。
又例如，作为另一种示例，也可以是，插在槽位11中的单板3能够在槽位11中左右横向滑行，每一组第一光接口21所在的托板22也能够在机柜1中左右横向滑行。这样，第一光接口21和第二光接口31可插拔连接中，让对应的托板22和/或单板3左右滑行。
以上是单板3与光纤背板2的光对接，而单板3也具有一些电接口，如电源接口，又如控制信号接口等，那么，如图4所示，通信设备还包括电连接背板4，电连接背板4位于机柜1中，各个单板3的侧部具有电接口34，当单板3位于槽位11中时，单板3的电接口34与电连接背板4电连接。
其中，电连接背板4可以是印刷电路板(printed circuit board，PCB)背板，也可以是电缆(cable)背板，本实施例对电连接背板4的具体类型不做限定。
例如，如图4所示，电连接背板4与光纤背板2位于槽位11的同一侧，单板3不仅具有一组第二光接口31，还具有电接口34，单板3的第二光接口31和电接口34位于单板3的同一侧。这样，单板3插在槽位11中以后，向靠近光纤背板2的方向滑行，滑行到底时，参考图5所示，单板3的电接口34与电连接背板4电连接，单板3的第二光接口31与光纤背板2的第一光接口21对接。
又例如，如图7和图8所示，电连接背板4在槽位11的槽底位置处，而各个单板3具有电接口34，但是电接口34和第二光接口31位于单板3的不同侧，例如，第二光接口31位于单板3的第一侧，电接口34位于单板3的第二侧，第一侧和单板3的面板相邻，而第二侧和单板3的面板相对，这样，单板3插入槽位11中且插到位时，单板3第二侧的电接口34与槽底处的电连接背板4电连接。
需要指出的是，单板3的第二侧具有电接口34，电连接背板4位于槽位11的槽底的方案中，可以是单板3不在槽位11中横向滑行，而是各组第一光接口21在机柜1中横向滑行(参考图7和图8所示)。也可以是，单板3能够在槽位11中横向滑行，但是单板3在横向滑行中，与单板3电连接的电连接背板4也需要跟着单板3一起滑行，或者，电连接背板4不随着单板3一起横向滑行，但是单板3的电接口34与电连接背板4之间通过跳线连接，而跳线的长度大于单板3的单程最大滑行行程，其中，跳线也即是位于机柜1中的导线。
在一种示例中，单板3的第二光接口31与光纤背板2的第一光接口21需要精确对准，那么，相应的，如图4和图5所示，各个单板3的第一侧具有多个第一定位结构33，光纤背板2具有多个第二定位结构23。其中，单板3的第一侧也即是具有第二光接口31的一侧，其中，第一定位结构33和第二定位结构23的数量相等，例如，各个单板3的第一侧具有两个第一定位结构33，光纤背板2具有两个第二定位结构23。
第一定位结构33和第二定位结构23匹配，例如，第一定位结构33可以是柱状结构，第二定位结构23为管状结构，又例如，第一定位结构33为柱状结构，第二定位结构23为凹槽结构。
以单板3向靠近光纤背板2的方向滑行示例，单板3插入槽位11中以后，在槽位11中向靠近光纤背板2的方向滑行，在滑行中，首先第一定位结构33与第二定位结构23一一匹配，然后在多个第一定位结构33与多个第二定位结构23一一匹配的情况下，单板3的第二光接口31和光纤背板2的第一光接口21对接。
需要指出的是，单板3的光接口31和电接口34位于单板3同一侧的方案中，单板3和电连接背板4连接所使用的定位结构，与单板3和光纤背板2连接所使用的定位结构相同，参考图4和图5所示。而单板3的光接口31和电接口34位于单板3异侧的方案中，单板3和电连接背板4连接所使用的定位结构，与单板3和光纤背板2连接所使用的定位结构不同，参考图7和图8所示。
在一种示例中，当位于槽位11中的单板3与光纤背板2连接时，可以通过锁止结构，稳定单板3与光纤背板2的连接。
例如，对于单板3在槽位11中滑行的方案，当单板3在槽位11中滑行到底时，通过锁止结构将单板3锁止在当前位置，以使单板3与光纤背板2稳定连接。其中，锁止结构可以布置在单板3和槽位11内，例如，单板3具有凸起，槽位11的槽壁具有凹槽，当单板3横向滑到底时，单板3的凸起卡入槽位11的凹槽中，从而实现将单板3锁止在当前位置处。
其中，单板3的凸起可以是弹性凸起，在单板3的面板位置处可以具有按钮，在需要断开单板3与光纤背板2之间的连接时，只需要按压按钮，使单板3的凸起，从槽位11的凹槽中脱离，之后，操控单板3向远离光纤背板2的方向滑行，滑行到底以后，再将单板3从槽位11中拔出。
又例如，对于托板22在机柜1中滑行的方案，当托板22向靠近单板3的方向滑行到底时，通过锁止结构，将该托板22锁止在当前位置，以使单板3与光纤背板2稳定连接。其中，锁止结构可以布置在托板22和机柜1内，例如，托板22具有凸起，机柜1对应位置具有凹槽，当托板22横向滑行到底时，托板22的凸起卡在机柜1的凹槽中，从而实现将托板22上的一组第一光接口21锁止在当前位置处。
其中，托板22的凸起可以是弹性凸起，在托板22的端部具有按钮，在需要断开连接时，只需要按压按钮，使托板22的凸起，从机柜1的凹槽中脱离，之后操控托板22向远离单板3的方向滑行，完全脱离以后，再将单板3从槽位11中拔出。
需要指出的是，对于单板3在槽位11中可横向滑行，第一光接口21在机柜1中不可横向滑行的方案中，第一光接口21也可以不布置在托板22上，而是直接固定在光纤背板2的背板本体20上(参考图2所示)。
以上是插入槽位11中的单板3与光纤背板2实现连接的方式介绍，下降将介绍通信设备进一步的防尘方案。
如图9所示，为通信设备的结构示意图，参考图9所示，机柜1包括隔板12，隔板12位于多个槽位11和光纤背板2之间，且隔板12与光纤背板2平行，这样隔板12可以作为多个槽位11的一个槽壁(如左槽壁或右槽壁)。这样，隔板12将多个槽位11所在空间，与多组第一光接口21所在空间隔开，那么，气流在空闲槽位中流通，不会窜入第一光接口21所在空间，进一步有利于第一光接口21的防尘。
由于光纤背板2与插入槽位11中的单板3需要连接，所以，隔板12具有打开和关闭功能，当槽位11为空闲槽位时，隔板12在空闲槽位对应的位置处处于关闭状态，当槽位11插有单板3，且单板3需要与光纤背板2连接时，隔板12在该槽位11对应的位置处处于打开状态。
例如，如图10和图11所示，隔板12在沿着高度方向上具有多个可旋转挡板121，其中可旋转挡板121的数量与槽位11的数量相同，且隔板12位于机柜1中，可旋转挡板121与槽位11一一位置相对。对于多个可旋转挡板121中的任意一个可旋转挡板121，在所对应的槽位11内的单板3需要与光纤背板2连接的情况下，该可旋转挡板121处于旋开状态(参考图11所示)，而在所对应的槽位11为空闲槽位的情况下，该可旋转挡板121处于关闭状态(参考图10所示)。
参考图11所示，可旋转挡板121处于旋开状态时，与隔板12的本体部分垂直，参考图10所示，可旋转挡板121处于关闭状态时，与隔板12的本体部分平行。
在一种示例中，默认状态下，或者说自然状态下，可旋转挡板121处于关闭状态，如图10所示，单板3插入槽位11中，但是与光纤背板2连接之前，所对应的可旋转挡板121处于关闭状态。如图11所示，单板3插入槽位11中以后，在单板3的横向滑行下，将所对应的可旋转挡板121旋开。或者，单板3插入槽位11中以后，在单板3对应的一组第一光接口21的横向滑行下，将所对应的可旋转挡板121旋开。
这样，空闲槽位与对应的一组第一光接口21之间，有处于关闭状态的可旋转挡板121物理隔开，进一步避免散热的气流，将灰尘带入第一光接口21附近，有利于光纤背板2的第一光接口21防尘。
在一种示例中，参考图12所示，每个单板3的第一侧具有防尘框32，防尘框32的远离单板3本体部分的一侧敞口，单板3的一组第二光接口31均位于防尘框32中，且通过防尘框32的敞口外露。
参考图12所示，单板3第一侧的防尘框32将单板3第一侧的一组第二光接口31包围起来，这样，单板3与光纤背板2处于连接状态时，如图14所示，光纤背板2的第一光接口21也被防尘框32包围起来，进而，光纤背板2的第一光接口21与风道之间也有物理隔离，那么风道中的气流在为单板3散热中，不会窜入光纤背板2的第一光接口21处，进一步有利于光纤背板2的第一光接口21的防尘。
这样，如图9所示，槽位11中未插有单板3的情况下，或者，如图13所示，槽位11中插有单板3，但是单板3与对应的一组第一光接口21连接之前，该槽位11与所对应的一组第一光接口21之间，通过处于关闭状态的可旋转挡板121隔离，实现风道与第一光接口21之间的物理隔离。而在槽位11中插有单板3，且单板3的第二光接口31与所对应的一组第一光接口21连接的情况下，如图14所示，该单板3的防尘框32将该组第一光接口21包围起来，实现风道与第一光接口21之间的物理隔离。可见，无论单板3是否插入槽位11中，穿过各个槽位11的风道，与光纤背板2的各组第一光接口21之间都处于隔离状态，从而增强光纤背板2的防尘效果，使光纤背板2的第一光接口21不易受灰尘污染。
在本公开实施例中，该通信设备的光纤背板在机柜中的位置，邻近槽位的槽口所在位置，而不是位于槽底处，与槽口位置相对，那么，在槽口和槽底之间流通的气流，平行于光纤背板流通，而不是穿过光纤背板，所以，气流在风道中流通中，不易将灰尘带向光纤背板的第一光接口及其附近，有利于光纤背板的第一光接口防尘，进而有利于确保光通信质量良好。
另外，机柜1内具有隔板12，将多个槽位11所在空间，与光纤背板2所在空间隔离开，使气流的流动空间与光纤背板2所在空间隔开，进一步有利于光纤背板2的防尘。
另外，单板3的一组第二光接口31外具有防尘框32围着。这样，槽位中未插有单板时，因隔板的可旋转挡板121(与该槽位相对的可旋转挡板121)处于关闭状态，那么，该槽位与光纤背板的一组第一光接口之间通过处于关闭状态的可旋转挡板121隔开(参考图9所示)，灰尘不易进入到这一组第一光接口附近。槽位中插有单板时，光纤背板的一组第一光接口由该单板的防尘框包围(参考图14所示)，气流也不易将灰尘吹到这一组第一光接口附近。
因此，不管槽位是否空闲，光纤背板的各组第一光接口所在空间与气流流通空间始终处于隔离状态，那么气流就不易将灰尘带向第一光接口及附近，从而使光纤背板的第一光接口的光耦合面，能够长时间保持清洁干净，有利于确保通信设备的光通信质量。
