Description

一种柔性光纤带及带状光缆
本申请要求于2022年09月06日提交中国专利局、申请号为202211085562.1、申请名称为“一种柔性光纤带及带状光缆”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光缆技术领域，尤其涉及一种柔性光纤带及带状光缆。
背景技术
随着电子信息技术的发展和人们对沟通交流需求的增加，光纤提供了优于常规通信线路的优点。与传统的有线网络相比，光纤通信网络可以以显著提高的速度传输显著增多的信息。在世界范围内，通过光缆传输的数据量持续增长。由于云计算的扩展，在数据中心中尤其如此，这要求在有限的物理空间中接收和传输数据。因此，对高纤维数和高纤维密度的光缆的需求不断增长。随着高纤维数的需求日益加强，具备可卷绕功能的光纤带应运而生。所谓的具备可卷绕功能的光纤带是指若干根光纤沿纵向相邻地平行排列后，通过喷嘴将可固化的粘接剂喷涂在若干光纤纵向排列后形成的上表面，粘接剂固化后即形成柔性光纤带，可在光纤带宽度方向上卷曲或折叠。
然而，光纤带的柔性和坚固性虽然都是由粘接剂的轨迹以及量决定的，但是却是两个对立矛盾的指标，粘接剂的轨迹设置不当的话不仅会增加喷嘴的工作精度要求，而且可能会过分增加光纤带的坚固性而减少柔性。此外，虽然目前现有的柔性光纤带有提出双面设置粘接剂，但是其轨迹简单，过分增加了光纤带的坚固性而损失了光纤带的柔性。
发明内容
本发明为了解决现有技术中存在的问题，提供一种柔性光纤带及带状光缆。本申请的柔性光纤带即具有良好的稳定性，又提高了光纤带的柔性。
第一方面，本申请实施例提供了一种柔性光纤带，包括由若干光纤在同一平面相邻平行排列形成的光纤排列；所述光纤排列的正排列面和背排列面上分别沿所述光纤排列的长度方向间隔设置连接部，所述连接部为倾斜设置的直线形，且所述正排列面和/或背排列面的连接部为不均匀间隔分布；所述连接部材质均为树脂，正面连接部的树脂粘度比背面连接部的树脂粘度高，正面连接部的树脂抗拉强度比背面连接部的树脂抗拉强度高。
在一些实施例中，正面连接部的密度大于背面连接部的密度。
在一些实施例中，正排列面和/或背排列面的连接部包括短连接部和长连接部。
在一些实施例中，短连接部设置在所述光纤排列面的边缘位置，长连接部横跨粘接所述光纤排列。
在一些实施例中，所述正面连接部和所述背面连接部的轨迹为周期排列，并且排列周期相同。

在一些实施例中，正排列面和/或背排列面上短连接部的设置密度大于长连接部的设置密度。
第二方面，本申请实施例还提供了一种柔性光纤带，包括由若干光纤在同一平面相邻平行排列形成的光纤排列；所述光纤排列的正排列面和背排列面上分别沿所述光纤排列的长度方向间隔设置连接部；所述连接部为倾斜设置的直线形，所述连接部材质均为树脂，正面连接部的树脂粘度比背面连接部的树脂粘度高，正面连接部的树脂抗拉强度比背面连接部的树脂抗拉强度高；所述正排列面和/或背排列面的连接部包括短连接部阵列和长连接部阵列，正排列面或背排列面中至少一面的短连接部阵列和长连接部阵列沿所述光纤排列长度方向交替排列。
在一些实施例中，所述长连接部阵列包括至少一条横跨粘接所述光纤排列的长连接部，所述短连接部阵列包括至少一条仅设置在所述光纤排列面边缘位置的短连接部。
在一些实施例中，所述短连接部阵列和长连接部阵列的轨迹为周期排列，并且排列周期相同，在一个轨迹周期内同一排列面上的连接部平行设置，所述正排列面和所述背排列面的连接部的倾斜方向相反。
第三方面，本申请实施例提供了一种带状光缆，其包括由内至外依次包括光纤束单元、海绵包带、松套管、外护套，所述光纤束单元包括绞合设置的若干光纤束和绕扎在所述绞合设置的若干光纤束上的色线，所述光纤束包括卷绕设置的如上述任一项实施例中的柔性光纤带；所述光纤束单元和所述海绵包带之间以及所述光纤束单元之间的空间还填充阻水纱；海绵包带纵包包覆所述光纤束单元和阻水纱；在所述外护套壁内对称嵌入若干增强件。

下面结合附图以及具体实施例对本发明进行详细说明。
实施例一
如图1所示，本实施例的柔性光纤带，包括在同一平面并排配置形成光纤排列的若干光纤11，其中光纤排列中的不同光纤可以设置有不同的颜色。所述光纤排列的正排列面A设置纵向间隔的正面长连接部12，背排列面B设置纵向间隔的背面长连接部14，如图1中实线表示的是正排列面的正面长连接部12，虚线表示的是背排列面的背面长连接部14。所述正面长连接部12和背面长连接部14呈一定倾斜角度的直线形状，并在所述光纤排列上不均匀分布。在本实施例中，正面长连接部12和背面长连接部14长度、倾斜角度及倾斜方向一致，且在该倾斜角度下，同一条连接部上光纤焊缝之间的距离为10-15mm。所述正面长连接部12与背面长连接部14分布密度不同，正面长连接部12比背面长连接部14设置的密度更大，即正面长连接部12比背面长连接部14设置的数量更多。当光纤带向背面卷曲或折叠时，由于背面长连接部14较少，光纤带更易向背面卷曲，光纤带的柔性达到最佳。
同时，为确保光纤带在卷绕过程中粘结点不脱露导致光纤散带，所述正面连接部和背面连接部采用不同的抗拉强度与粘度树脂材料，正面连接部的树脂粘度比背面连接部树脂的粘度高，正面连接部树脂的拉伸强度比背面连接部树脂的拉伸强度高。
在一些实施例中，正面树脂的粘度比背面树脂的粘度高100-2000cps，正面树脂的拉伸度比背面树脂的拉伸度高5-20Mpa。优选的，正面连接部树脂在25℃时的粘度为5500～6500cps，抗拉强度35～45MPa；背面连接部树脂在25℃时的粘度为4500～5500cps，抗拉强度25～35MPa。当光纤带向背面卷曲或折叠时，正面长连接部12具有更高的拉伸度，保证光纤 带被卷绕或折叠成预定的形状，而连接部不会由于张力过大而脱落。
实施例二
本实施例的柔性光纤带结构与实施例一的不同之处在于连接部的轨迹不同，设置在光纤排列边缘的短连接部密度大于横跨光纤排列的长连接部密度。
本实施例的柔性光纤带，包括在同一平面并排配置形成光纤排列的若干光纤11，所述光纤排列的正排列面设置纵向间隔的正面长连接部12和正面短连接部13，背面设置纵向间隔的背面长连接部14和背面短连接部15，所述连接部呈一定倾斜角度的直线形状，并在所述光纤排列上不均匀分布。在本实施例中，连接部的长度不同，具有长连接部和短连接部，所述长连接部粘接整个光纤排列，所述短连接部粘接光纤排列的边缘光纤，短连接部的密度大于长连接部的密度，即粘接边缘光纤的连接部比粘接中间光纤的连接部设置的数量更多。
本实施例中，如图2a所示，在其中一个连接部轨迹周期T内，光纤排列的正排列面设置有1条正面长连接部12,4条正面短连接部13，其中2条正面短连接部13设置在光纤排列的上侧边缘C，另外2条正面短连接部13设置在光纤排列的下侧边缘D，正面长连接部12和正面短连接部13均平行设置。在光纤排列的背排列面设置1条背面长连接部14,4条背面短连接部15，其中2条背面短连接部15设置在光纤排列的上侧边缘，另外2条背面短连接部15设置在光纤排列的下侧边缘，背面长连接部14和背面短连接部15均平行设置。当正面连接部和背面连接部印射在同一平面时，正面长连接部12和背面长连接部14为轴对称设置，光纤排列同一侧的正面短连接部13和背面短连接部15为轴对称设置，且正面连接部和背面连接部在光纤排列的边缘首尾相接形成若干V形。这种针对边缘光纤有加强粘接力的设计，使得边缘光纤的稳定性高于中间，当光纤带向背面卷曲或折叠时可以有效阻止边纤的松散。
在一些实施例中，如图2b所示，在其中一个连接部轨迹周期内，光纤排列的正排列面设置有2条正面长连接部12,4条正面短连接部13，其中2条正面短连接部13设置在光纤排列的上侧边缘，另外2条正面短连接部13设置在光纤排列的下侧边缘，正面长连接部12和正面短连接部13 均平行设置。在光纤排列的背排列面设置2条背面长连接部14,4条背面短连接部15，其中2条背面短连接部15设置在光纤排列的上侧边缘，另外2条背面短连接部15设置在光纤排列的下侧边缘，背面长连接部14和背面短连接部15均平行设置。当正面连接部和背面连接部印射在同一平面时，正面长连接部12和背面长连接部14为轴对称设置，光纤排列同一侧的正面短连接部13和背面短连接部15为轴对称设置，且在光纤排列的边缘形成若干V形，在光纤排列中间形成若干X形。针对边缘光纤有加强粘接力的设计的同时，适当加强中间位置的粘结力，可以有效阻止边纤的松散，同时，当受到外力时，保证光纤带的强度，避免中间光纤脱落。
在一些实施例中，如图2c所示，在其中一个连接部轨迹周期内，光纤排列的正排列面设置1条正面长连接部12,1条正面短连接部13，正面短连接部13设置在光纤排列的一侧，正面长连接部12和正面短连接部13均平行设置。光纤排列的背面设置1条背面长连接部14,1条背面短连接部15，背面短连接部15设置在与正面短连接部13相对的另一侧光纤排列边缘，背面长连接部14和背面短连接部15均平行设置。当正面连接部和背面连接部印射在同一平面时，正面长连接部12和背面长连接部14为轴对称设置，且正面长连接部12和背面长连接部14在光纤排列的边缘形成V形。在连续周期中，长连接部形成N形。针对边缘光纤有加强粘接力的设计，当光纤带向背面卷曲或折叠时可以有效阻止边纤的松散。同时，长连接部和短连接部间隔密度相同，在制造时，简化工艺，提高生产效率。
实施例三

在本实施例中，针对边缘光纤有加强粘接力的设计，当光纤带向背面卷曲或折叠时可以有效阻止边纤的松散。同时，正面连接部的数量大于背面连接部的数量，更利于光纤带向背面卷曲或折叠，且正排列面的中间光纤粘结力被加强，提高柔性光纤带的稳定性。
在一些实施例中，如图3b所示，在其中一个连接部轨迹周期内，光纤排列的正排列面设置有2条正面长连接部12,4条正面短连接部13，其中2条正面短连接部13设置在光纤排列的上侧边缘，另外2条正面短连接部13设置在光纤排列的下侧边缘，正面长连接部12和正面短连接部13均平行设置。在光纤排列的背排列面设置2条背面长连接部14,背面长连接部14也均平行设置。当正面连接部和背面连接部印射在同一平面时，正面长连接部12和背面长连接部14为轴对称设置，且正面长连接部12和背面长连接部14在光纤排列的边缘收尾相接形成V形，在连续周期中，长连接部形成N形。
