本申请涉及光通信技术领域，尤其涉及一种多层堆叠式光纤载体、通信设备和装配方法。
在现代通信网中，全光网可以克服电子交换在容量上的瓶颈限制，可以大量节省建网成本，提高网络的灵活性和可靠性，因此全光网是未来宽带通信网的发展方向。光交换是全光网络的关键技术之一，光交换是指不经过任何光电转换，将输入端的光信号直接交换到任意的光输出端。
如图1所示，大容量的光通信设备包括输入光纤阵列011、输出光纤阵列012、光交换机02和控制单元等结构，在该光交换机中，如何将输入光纤阵列011或输出光纤阵列012包括的几十上百根光纤固定到预设位置以使光纤中的光路准确对准光交换机02是一个关键技术点。
为了将输入光纤阵列011或输出光纤阵列012中的光纤准确对准光交换机02，如图2所示，目前使用的方法是在一块板04上加工相应数量的孔03，并保证这些孔03的直径精度和位置精度，然后将输入光纤阵列011或输出光纤阵列012中的多个光纤插入相应的孔03中，以通过孔03的直径和位置尺寸来确保光纤及光路的准确。但是，这样就需要将大量超高精度且具有一定深度的孔03准确地加工到同一块板04上，加工方式有限、效率低、成本高，且光纤在穿过孔的过程中容易被孔03的边缘划伤，从而造成光纤的性能指标下降。
为了避免上述问题，图3和图4为现有技术中的一种多层堆叠式光纤载体，包括多个光纤载体05，该多个光纤载体05由下至上依次堆叠，每个光纤载体05的上表面均设有一排光纤安装槽06，该光纤安装槽06用于安装光纤，这样，可以通过控制相邻两个光纤安装槽06之间的位置精度以及光纤载体05沿堆叠方向上的尺寸精度来确保光纤及光路的准确。在本技术方案中，采用开放式的光纤安装槽06替代上述封闭式的圆孔03，能够降低加工难度，增加光纤在光纤载体上的固定长度，保证光纤的垂直度，同时光纤埋入光纤安装槽06内以实现安装，能够避免光纤被划伤。但是，由于光纤载体05不可避免地会存在一定的加工误差，堆叠多个光纤载体05时会存在公差累积的问题，因此单个光纤载体05沿其堆叠方向上的尺寸精度需要比最终的多层堆叠式光纤载体沿堆叠方向上的尺寸精度高一个数量级以上。如下例所示：当单个光纤载体05沿其堆叠方向上的尺寸为1.0±0.01时，即该光纤载体05可能具有的极限尺寸为1.01，堆叠10个光纤载体05所形成的多层堆叠式光纤载体沿堆叠方向上的尺寸可能为10.10，公差比单个光纤载体05的精度降低了 10倍。如果希望将堆叠后的精度控制在±0.01的水平，那么单个光纤载体05沿堆叠方向上的尺寸精度就需要提高一个数量级。由此造成了光纤载体05加工困难，成本高昂。
发明内容
本申请的实施例提供一种多层堆叠式光纤载体、通信设备和装配方法，能够降低光纤载体的加工难度，减小光纤载体的加工成本。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，本申请实施例提供一种多层堆叠式光纤载体，包括多个光纤载体模块，多个所述光纤载体模块沿第一方向依次堆叠设置，每个所述光纤载体模块均包括光纤载体和调整结构，所述光纤载体上设有光纤安装部，所述调整结构用于使相邻两个所述光纤载体模块中所述光纤载体上的光纤安装部之间沿第一方向的距离等于目标值；其中，所述第一方向为任意一个方向，所述目标值为光交换机上与所述相邻两个光纤载体模块中所述光纤载体上的光纤安装部分别对应的两部分光输入口或光输出口之间的距离。
与现有技术相比，本申请实施例提供的多层堆叠式光纤载体，每个光纤载体对应设有调整结构，光纤载体和对应的调整结构组成光纤载体模块，由于该调整结构用于使相邻两个光纤载体模块中光纤载体上的光纤安装部之间沿第一方向的距离等于目标值，该目标值为光交换机上与该相邻两个光纤载体模块中光纤载体上的光纤安装部分别对应的两部分光输入口或光输出口之间的距离，因此通过调整结构能够保证各个光纤安装部之间的位置精度，使光纤中的光路能够准确对准光交换机，而对光纤载体的尺寸精度并无较高要求，因此能够降低光纤载体的加工难度和加工成本。
可选的，光纤载体沿所述第一方向的两端端面分别为第一表面和第二表面，多个光纤载体模块中光纤载体的第一表面朝向同一侧，光纤安装部为设置于光纤载体的第一表面上的光纤安装槽，调整结构设置于光纤载体的第二表面上。这样，一方面，由于光纤安装部为设置于光纤载体的表面上的光纤安装槽，因此能够降低光纤安装部的加工难度，且光纤可以采用埋入式安装方式安装于该光纤安装槽内，因此能够避免光纤在安装时被划伤；另一方面，由于多个光纤载体模块中光纤载体的第一表面朝向同一侧，光纤安装部设置于光纤载体的第一表面上，调整结构设置于光纤载体的第二表面上，因此，仅通过调整结构在光纤载体的第二表面远离第一表面的一侧进行调整，即可使相邻两个光纤载体模块中光纤载体上的光纤安装部之间沿第一方向的距离等于目标值，因此调整难度较低，操作方便，容易实现。
可选的，调整结构通过胶水、螺纹连接件、卡接件等固定于光纤载体的第二表面上。这样，能够固定调整结构与光纤载体之间的相对位置，防止调整结构在光纤载体的第二表面上窜动。
可选的，调整结构仅与光纤载体的第二表面接触，调整结构与光纤载体之间不固定。这样，在装配形成光纤载体模块时，只需将调整结构放置于光纤载体的第二表面上的预设位置即可，耗时较短，装配效率较高。
可选的，调整结构为调整块。通过计算，选择合适尺寸的调整块可以使相邻两个光纤载体模块中光纤载体上的光纤安装部之间沿第一方向的距离等于目标值，由于调整块的形状通常简单，因此能够采用高精密加工方法加工该调整块，且相比于光纤载体，调整块的尺寸较小，因此更易于保证调整块的加工精度。
可选的，调整块的形状为球体、圆柱体、正方体或者长方体，此时，调整块的形状简 单，能够采用高精密加工方法加工，以保证调整块的尺寸精度。
可选的，调整结构为伸缩机构。这样，可通过伸缩机构伸缩至合适的尺寸，以调整相邻两个光纤载体模块中光纤载体上的光纤安装部之间沿第一方向的距离，使得该距离达到目标值。
可选的，伸缩机构为直线型超声波电动机。直线型超声波电动机的尺寸可以制作得非常小，且该直线型超声波电动机能够在电信号的驱动下伸缩至合适尺寸，以使相邻两个光纤载体模块中光纤载体上的光纤安装部之间沿第一方向的距离等于目标值。此结构简单，容易实现。
可选的，光纤安装槽沿第二方向延伸，每个光纤载体模块包括多个调整结构，该多个调整结构沿与第二方向垂直并与第二表面平行的第三方向依次排列，其中，第二方向为与第一表面平行的任意一个方向。这样，一方面，通过多个调整结构同时支撑光纤载体，能够保证对光纤载体的支撑稳定性，从而能够保证多个光纤载体模块的堆叠稳定性；另一方面，采用多个调整结构分别在光纤载体的第二表面上的多个位置调整，能够有效补偿光纤载体的第一表面与第二表面之间的平行度误差。
可选的，光纤安装槽为多个，多个光纤安装槽并排设置。这样，一个光纤载体可以同时承载多个光纤，能够提高多层堆叠式光纤载体的容量。

可选的，光纤载体的第二表面上对应调整结构的位置设有限位槽，调整结构的一部分位于该限位槽内。这样，第一方面，当调整结构固定于光纤载体上时，可以通过该限位槽标记调整结构在光纤载体上的固定位置，以便于在装配调整结构时，能够更为方便地将调整结构固定于光纤载体上的预设位置；第二方面，当调整结构不固定于光纤载体上，而仅是放置于光纤载体上时，可以通过限位槽限制调整结构的位置，避免调整结构在光纤载体的第二表面上窜动；第三方面，调整结构的一部分沉入限位槽内设置，能够在一定程度上增大调整结构的尺寸，避免调整结构的尺寸过小而使其加工难度增大。
可选的，限位槽为矩形槽、V型槽或者U型槽。此结构简单，容易加工。

需要说明的是，相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离也即是指：相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离，该相邻两个光纤载体11分别属于相邻的两个光纤载体模块1。其中，每个光纤载体11上可以设置一个光纤安装部111，也可以设置一排光纤安装部111，该一排光纤安装部111包括多个光纤安装部111，在此不做具体限定。当每个光纤载体11上设置一个光纤安装部111时，多个光纤载体11上的多个光纤安装部111可以沿第一方向X对齐排列，也可以沿第一方向X错位排列，相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离是指：相邻两个光纤安装部111之间沿第一方向X的距离。当每个光纤载体11上设置一排光纤安装部111时，多个光纤载体11上的多排光纤安装部111可以沿第一方向X对齐排列，也可以沿第一方向X错位排列，相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离是指相邻两排光纤安装部111之间沿第一方向X的距离。在一些实施例中，如图5和图6所示，每个光纤载体11上设置一排光纤安装部111，多个光纤载体11上的多排光纤安装部111沿第一方向X对齐排列，相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离是指相邻两排光纤安装部111之间沿第一方向X的距离。
光纤安装部111可以为设置于光纤载体11沿第一方向X的一端端面上的光纤安装槽，也可以为设置于光纤载体11沿第一方向X的中部的光纤安装孔，在此不做具体限定。在一些实施例中，如图5和图6所示，光纤安装部111为设置于光纤载体11沿第一方向X的一端端面上的光纤安装槽，这样，光纤可以采用埋入式安装方式安装于光纤安装部111内，避免光纤在安装过程中被划伤，同时可以降低光纤安装部111的开设难度。
为了保证调整结构12能够使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值，调整结构12应设置于光纤载体11沿第一方向X的至少一端端面上，以使调整结构12能够对光纤载体11在第一方向X上的位置起到调整作用，从而使相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离能够达到目标值。调整结构12可以仅设置于光纤载体11沿第一方向X的一端端面上，也可以设置于光纤载体11沿第一方向X的两端端面上，在此不做具体限定。在一些实施例中，如图5和图6所示，调整结构12仅设置于光纤载体11沿第一方向X的一端端面上，这样，只需在光纤载体11的一侧进行调整，即可使相邻两个光纤载体11上的光纤安装部111之间沿第一方向X的距离达到目标值，因此调整难度较低，操作方便，容易实现。
与现有技术相比，本申请实施例提供的多层堆叠式光纤载体，每个光纤载体11对应设有调整结构12，光纤载体11和对应的调整结构12组成光纤载体模块1，由于该调整结构12用于使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值，该目标值为光交换机上与该相邻两个光纤载体模块1中光纤载体11上的光纤安装部111分别对应的两部分光输入口或光输出口之间的距离，因此通过调整结构12能够保证各个光纤安装部111之间在第一方向X上的位置精度，使光纤中的光路能 够准确对准光交换机，而对光纤载体11沿第一方向X的尺寸精度并无较高要求，因此能够降低光纤载体11的加工难度和加工成本。
光纤载体11的材料可以为玻璃、硅、金属、塑料等材料，在此不做具体限定。
在一些实施例中，如图5和图6所示，光纤载体11沿所述第一方向X的两端端面分别为第一表面a和第二表面b，多个光纤载体模块1中光纤载体11的第一表面a朝向同一侧，光纤安装部111为设置于光纤载体11的第一表面a上的光纤安装槽，调整结构12设置于光纤载体11的第二表面b上。这样，一方面，由于光纤安装部111为设置于光纤载体11的表面上的光纤安装槽，因此能够降低光纤安装部111的加工难度，且光纤100可以采用埋入式安装方式安装于该光纤安装槽内，因此能够避免光纤在安装时被划伤；另一方面，由于多个光纤载体模块1中光纤载体11的第一表面a朝向同一侧，光纤安装部111设置于光纤载体11的第一表面a上，调整结构12设置于光纤载体11的第二表面b上，因此，仅通过调整结构12在光纤载体11的第二表面b远离第一表面a的一侧进行调整，即可使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值，因此调整难度较低，操作方便，容易实现。
在一些实施例中，调整结构12可以通过胶水、螺纹连接件、卡接件等固定于光纤载体11的第二表面b上，这样，能够固定调整结构12与光纤载体11之间的相对位置，防止调整结构12在光纤载体11的第二表面b上窜动。同理的，在一些实施例中，相邻两个光纤载体模块1之间也可以通过胶水、螺纹连接件、卡接件等固定在一起，以防止相邻两个光纤载体模块1之间产生相对移动。
在另外一些实施例中，调整结构12可以仅与光纤载体11的第二表面b接触，调整结构12与光纤载体11之间不固定，这样，在装配形成光纤载体模块1时，只需将调整结构12放置于光纤载体11的第二表面b上的预设位置即可，因此耗时较短，装配效率较高。同理的，在一些实施例中，在依次堆叠多个光纤载体模块1时，也可以使相邻两个光纤载体模块1接触，该相邻的两个光纤载体模块1之间并未固定，这样，在装配多个光纤载体模块1以形成多层堆叠式光纤载体时，只需依次堆叠放置多个光纤载体模块1即可，因此耗时较短，堆叠效率较高。
需要说明的是，当调整结构12与光纤载体11之间和/或相邻两个光纤载体模块1之间未固定时，在完成多层堆叠式光纤载体的装配之后，可以采用夹紧装置由多层堆叠式光纤载体沿第一方向X的两端夹紧该多层堆叠式光纤载体，以依靠调整结构12与光纤载体11之间和/或相邻两个光纤载体模块1之间的摩擦力实现调整结构12与光纤载体11之间和/或相邻两个光纤载体模块1之间的相对位置固定。
其中，夹紧装置的结构为机械技术领域中的常用结构，且其结构形式有多种，比如螺旋夹紧机构、偏心夹紧机构、端面凸轮夹紧机构等等，在此不做具体限定。
在一些实施例中，如图5和图6所示，调整结构12为调整块。通过计算，选择合适尺寸的调整块可以使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值，由于调整块的形状通常简单，因此能够采用高精密加工方法加工该调整块，且相比于光纤载体11，调整块的尺寸较小，因此更易于保证调整块的加工精度。
可选的，调整块的形状为球体、圆柱体、正方体或者长方体，此时，调整块的形状简单，能够采用高精密加工方法加工，以保证调整块的尺寸精度。
可选的，调整块的材料可以为玻璃、硅、金属、塑料等材料，在此不做具体限定。且调整块的加工方式可以为切削、磨削、蚀刻等，在此不做具体限定。
在另外一些实施例中，调整结构12为伸缩机构。这样，可通过伸缩机构伸缩至合适的尺寸，以调整相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向的距离，使得该距离达到目标值。
伸缩机构可以为电致伸缩机构、磁致伸缩机构、热致伸缩机构等等，在此不做具体限定。
在一些实施例中，伸缩机构为直线型超声波电动机。直线型超声波电动机的尺寸可以制作得非常小，且该直线型超声波电动机能够在电信号的驱动下伸缩至合适尺寸，以使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值。此结构简单，容易实现。
在一些实施例中，如图5和图6所示，光纤安装槽沿第二方向Y延伸，每个光纤载体模块1包括多个调整结构12，该多个调整结构12沿与第二方向Y垂直并与第二表面b平行的第三方向Z依次排列。这样，一方面，通过多个调整结构12同时支撑光纤载体11，能够保证对光纤载体11的支撑稳定性，从而能够保证多个光纤载体模块1的堆叠稳定性；另一方面，采用多个调整结构12分别在光纤载体11的第二表面b上的多个位置调整，能够有效补偿光纤载体11的第一表面a与第二表面b之间的平行度误差。
在上述实施例中，需要说明的是，第二方向Y为与第一表面a平行的任意一个方向。
每个光纤载体模块1包括的调整结构12的数量可以为两个、三个、四个等等，在此不做具体限定。
在一些实施例中，如图5、图6和图7所示，光纤安装槽为多个，多个光纤安装槽并排设置。这样，一个光纤载体11可以同时承载多个光纤，能够提高多层堆叠式光纤载体的容量。
在一些实施例中，如图5和图6所示，每个光纤载体模块1包括两个调整结构12，两个调整结构12分别设置于第二表面b沿第三方向Z上的两端。这样，第一方面，通过两个调整结构12同时支撑光纤载体11，能够保证对光纤载体11的支撑稳定性，从而能够保证多个光纤载体模块1的堆叠稳定性；第二方面，采用两个调整结构12分别在光纤载体11的第二表面b沿第三方向Z的两端调整，能够有效补偿光纤载体11的第一表面a与第二表面b之间的平行度误差；第三方面，光纤载体模块1包括的调整结构12的数量较少，光纤载体模块1的组成简单，装配难度较低。
在一些实施例中，如图7所示，光纤载体11的第二表面b上对应调整结构的位置设有限位槽112，如图5所示，调整结构12的一部分位于该限位槽112内。这样，第一方面，当调整结构12固定于光纤载体11上时，可以通过该限位槽112标记调整结构12在光纤载体11上的固定位置，以便于在装配调整结构12时，能够更为方便地将调整结构12固定于光纤载体11上的预设位置；第二方面，当调整结构12不固定于光纤载体11上，而仅是放置于光纤载体11上时，可以通过限位槽112限制调整结构12的位置，避免调整结构12在光纤载体11的第二表面b上窜动；第三方面，调整结构12的一部分沉入限位槽112内设置，能够在一定程度上增大调整结构12的尺寸，避免调整结构12的尺寸过小而使其加工难度增大。
可选的，限位槽112为矩形槽、V型槽或者U型槽，此结构简单，容易加工。其中， 矩形槽、V型槽或者U型槽是指截面形状为矩形、V形或者U形的槽。
第二方面，本申请一些实施例还提供了一种通信设备，该通信设备包括多根输入光纤、多根输出光纤、第一多层堆叠式光纤载体、第二多层堆叠式光纤载体和光交换机，所述第一多层堆叠式光纤载体和所述第二多层堆叠式光纤载体均为如上任一实施例所述的多层堆叠式光纤载体；所述光交换机上设有光输入口阵列和光输出口阵列；多根所述输入光纤分别安装于所述第一多层堆叠式光纤载体中多个光纤载体上的光纤安装部内，多根所述输出光纤分别安装于所述第二多层堆叠式光纤载体中多个光纤载体上的光纤安装部内，所述第一多层堆叠式光纤载体和所述第二多层堆叠式光纤载体均与所述光交换机连接，且所述第一多层堆叠式光纤载体中多个光纤载体上的光纤安装部分别与所述光输入口阵列中的多个光输入口相对，所述第二多层堆叠式光纤载体中多个光纤载体上的光纤安装部分别与所述光输出口阵列中的多个光输出口相对。
与现有技术相比，本申请实施例提供的通信设备，由于该通信设备中，第一多层堆叠式光纤载体和第二多层堆叠式光纤载体均为如上任一技术方案所述的多层堆叠式光纤载体，因此通过该第一多层堆叠式光纤载体和第二多层堆叠式光纤载体分别固定多根输入光纤和多根输出光纤后，能够使多根输入光纤的光路与光交换机上的光输入口阵列对准，多根输出光纤与光交换机上的光输出口阵列对准，从而降低了光信号损失，保证了光通信质量，且对多层堆叠式光纤载体内的光纤载体的尺寸精度并无较高要求，因此能够降低光纤载体的加工难度和加工成本。
第三方面，本申请一些实施例提供一种装配方法，用于装配通信设备，通信设备包括多个光纤载体11，光纤载体11上设有光纤安装部111，如图5、图6和图8所示，该装配方法包括：
S100、在光纤载体11沿第一方向X的至少一端端面上安装调整结构12，以形成多个光纤载体模块1；
S200、沿第一方向X依次堆叠多个光纤载体模块1，以形成该多层堆叠式光纤载体；其中，多层堆叠式光纤载体中相邻两个光纤载体模块1内光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值H。
与现有技术相比，本申请实施例提供的装配方法，首先在光纤载体11沿第一方向X的至少一端端面上安装调整结构12，以形成多个光纤载体模块1，然后沿第一方向X依次堆叠多个光纤载体模块1，以形成该多层堆叠式光纤载体，其中，多层堆叠式光纤载体中相邻两个光纤载体模块1内光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值H，这样，通过增设了调整结构，使得相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值，因此通过调整结构12能够保证各个光纤安装部111之间在第一方向X上的位置精度，使光纤中的光路能够准确对准光交换机，而对光纤载体11沿第一方向X的尺寸精度并无较高要求，因此能够降低光纤载体11的加工难度和加工成本。
在一些实施例中，如图7所示，光纤载体11沿所述第一方向的两端端面分别为第一表面a和第二表面b，光纤安装部111为设置于光纤载体11的第一表面a上的光纤安装槽，如图9和图10所示，S100包括：
S101、测量光纤载体11在第二表面b上的预设位置处沿第一方向的实际厚度h1；
S102、将具有预设厚度h2的调整结构12安装于预设位置处，以获得在预设位置处沿 第一方向的厚度等于目标值H的光纤载体模块1；
其中，预设厚度h2等于目标值H与实际厚度h1之差；
S200包括：沿第一方向依次堆叠多个光纤载体模块1，并使多个光纤载体模块1中光纤载体11的第一表面a朝向同一侧。
这样一来，一方面，仅通过在光纤载体11的第二表面b设置调整结构12，即可使相邻两个光纤载体模块1中光纤载体11上的光纤安装部111之间沿第一方向X的距离等于目标值H，因此调整难度较低，操作方便，容易实现；另一方面，由于光纤安装部111为设置于光纤载体11的第一表面a上的光纤安装槽，因此能够降低光纤安装部111的加工难度，且光纤可以采用埋入式安装方式安装于该光纤安装槽内，因此能够避免光纤在安装时被划伤。
在一些实施例中，如图6所示，光纤安装槽沿第二方向Y延伸，第二表面b上具有多个预设位置，多个预设位置沿与第二方向Y垂直并与第二表面b平行的第三方向Z依次排列，S101包括：
测量光纤载体11在第二表面b上的多个预设位置处沿第一方向X的实际厚度h1；
S102包括：
将多个具有预设厚度h2的调整结构12分别安装于多个所述预设位置处，以获得在多个预设位置处沿第一方向X的厚度均等于目标值H的光纤载体模块1。
这样一来，一方面，通过多个调整结构12同时支撑光纤载体11，能够保证对光纤载体11的支撑稳定性，从而能够保证多个光纤载体模块1的堆叠稳定性；另一方面，采用多个调整结构12分别在光纤载体11的第二表面b上的多个位置调整，能够有效补偿光纤载体11的第一表面a与第二表面b之间的平行度误差。
在一些实施例中，调整结构12为调整块，在S102之前，还包括：根据目标值H与实际厚度h1之间的差异，选择具有预设厚度h2的调整块。此操作简单，容易实现，且由于调整块的形状通常简单，能够采用高精密加工方法加工该调整块，因此能够保证调整块的尺寸精度。
在一些实施例中，调整结构12为伸缩机构，在S102之前，还包括：根据目标值H与所述实际厚度h1之间的差异，驱动伸缩机构伸缩，以获得沿其伸缩方向的厚度为预设厚度h2的伸缩机构。此操作简单，容易实现。
在一些实施例中，在S200之前，还包括：将光纤固定于所述光纤安装槽内。这样，光纤埋入光纤安装槽内进行安装，能够避免光纤在安装时被划伤。
可选的，将光纤固定于光纤安装槽内包括：采用胶水将光纤固定于光纤安装槽内。这样，能够有效固定光纤，避免在依次堆叠多个光纤载体模块的过程中，光纤产生移位。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
