本申请中，所述的光导体是单模光纤或多模光纤，优选的型号是G.652或G.653或G.654或G.655或G.656或G.657或A1a或A1b或A1c。
本申请中，所述的光纤带是边缘粘结型或整体包覆型，每根光纤带内的传光部件的数量为2—24根，传光部件是单模光纤或多模光纤，优选的型号是G.652或G.653或G.654或G.655或G.656或G.657或A1a或A1b或A1c。
本申请中，所述的光纤是单模光纤或多模光纤，优选的型号是G.652或G.653或G.654或G.655或G.656或G.657或A1a或A1b或A1c。
本申请中，吊挂部件具有一定的硬度和韧性，其是通过线缆挤塑机挤塑拉制出来的；由于具有一定的硬度，故相邻的吊挂部件可实现支撑，同时，第一至第三吊挂本体也可支撑保持自身形状，并在承载吊挂连接部、吊挂体、电导体后仍保持原有形状；由于吊挂连接部较粗，且吊挂连接部、吊挂体两者的距离较短，故吊挂连接部、吊挂体不会在吊挂部件内部晃动。
本申请中，吊挂体的最下方与第一圆柱面相切时，吊挂体也与中心束管相贴/切，使产品更稳定；本申请中，吊挂部件具有开口时，导电体等极易放入吊挂体内部的空腔中，也极易取出；这种情况下，每个空腔中可放置多根外部包覆绝缘层的导电体，实现多路电力、多路电信号的传输。
本申请中，还可以混合使用图3及图7的吊挂部件，这样可以实现特殊的标识，如吊挂部件相同的颜色相同也可，如第一、二个吊挂部件为图3的，第三、四个吊挂部件为图7的，这样按顺序即可实现分辩；此外，吊挂部件具有不同颜色时，可实现两两区分。
本申请中，不局限于四个吊挂部件，还可以是具有多个吊挂部件。
本申请中，中心束管中具有光纤带或光纤、吊挂部件的空腔中具有光导体时，大大增加了光通信体的密度，使产品的价值及效率更高。
本申请中，中心束管中具有光纤带或光纤、吊挂部件的空腔中具有电导体时，实现了一根线缆，电力及光信号同传的功能，节省了多次敷设造成的管道费用的增加、敷设成本的增加等。
本申请中，由于吊挂部件的存在，使用拼合成型的方式，易于取及放，便于更换，不再需要像现有技术中那样，将多根绝缘线绞合成型的方式。
本申请中，吊挂部件中第一空腔及第二空腔的存在，不仅提供了更换导电体或光导体的通道；而且使得第二吊挂本体及第三吊挂本体具有微调的空间，此外，还使得导电体散发的热量有效地散发，使散热效果更好、在同等的发热条件下，电导体的载流量更大。
 工业实用性
本申请已实施并已取得样品。本发明具有以下主要有益效果：结构更稳定、光通信密度更大、敷设成本更低、更易成型及更换、散热效果更好、载流量更大。上述的实施例仅为本发明的优选技术方案，而不应视为对于本发明的限制。本发明的保护范围应以权利要求记载的技术方案，包括权利要求记载的技术方案中技术特征的等同替换方案为保护范围。即在此范围内的等同替换改进，也在本发明的保护范围之内。
