光电复合缆：“光纤+通信对绞线”型
Optical fiber + communication twisted pair line
1、结构示意图：以“GDTA-光纤+通信对绞线”为例。
1,Structural sketch: Taking “GDTA- optical fiber + communication twisted pair line” as an example.
2、光纤可以是三种方式：可以是φ250μm光纤、光纤带、φ900μm紧套光纤。
2,Optical fiber can be in three ways: it can be φ250μm fiber, ribbon fiber, φ900μm tight buffer fiber.
3、缆芯按照是否填充油膏分为三种：
（1）油膏填充型：光纤松套管和缆芯间隙都填充油膏。
（2）半干式：光纤松套管填充油膏，缆芯间隙填充阻水纱和阻水带。
（3）全干式：光纤松套管填充阻水纱，缆芯间隙填充阻水纱和阻水带。该结构不会对设备和环境造成污染，并且方便于施工。
3, the cable core is divided into three types according to whether or not to fill the ointment:
(1)The filling type of the ointment: The optical fiber loose tube and the cable core gap are filled with ointment.
(2) Semi dry type: The optical fiber loose tube filling ointment,the cable core gap filling water blocking yarn and water blocking tape.
(3)Full dry type:The fiber loose tube filled with water blocking yarn,the cable core gap filled with water blocking yarn and water blocking tape. The structure does not pollute the equipment and the environment, and is convenient for construction.
4、按照施工方式可以分为：架空型、管道型、沟槽型、直埋型、水下敷设型等，不同的施工方式有不同的护套类型。
4, In accordance with the construction method it can be divided into: aerial type, pipe type, groove type, directly buried, underwater laying type,etc, different construction methods have different sheath types.
5、光缆的结构分布、形状、性能和其他要求可以根据客户需求设计定制。
5,The structure, shape, performance and other requirements of optical cable can be customized according to customer requirements.
