What does composite cable mean?

　　Composite cable is a new type of cable with both optical cable and cable functions, mainly used to tranSMit power and data information. The following is a detailed explanation of composite cable:

　　I. Structure and composition

　　Composite fiber optic cable consists of an internal composition and an external protective layer. The internal composition mainly includes fiber optics, cables and auxiliary materials, while the external protective layer is used to protect the internal composition.

　　光纤：复合光缆的核心部分，用于传输光信号。光纤主要由光纤芯、光纤包层和光纤包护层三部分组成。光纤芯是用于传输光信号的中心部分，由高纯度的二氧化硅等材料制成。光纤包层是包裹在光纤芯外的一层材料，具有较低的折射率，能够将光信号有效地保持在光纤芯内传输。光纤包护层是在光纤包层外的一层材料，主要用于保护光纤。

　　电缆：复合光缆用于传输电信号的部分。电缆内部通常包含多根铜线，用于传输电信号。电缆通常比光纤粗，并由绝缘材料包裹，以防止电信号受到干扰。

　　辅助材料：复合光缆还需要一些辅助材料，如填充物和阻燃材料。填充物主要用于填满光纤和电缆之间的空隙，增强复合光缆的结构稳定性。阻燃材料则用于提高复合光缆的阻燃性能，以保护光纤和电缆免受火灾等意外事件的影响。

　　II. Working principle

　　When the composite cable transmits data, the optical fiber is used to transmit the optical signal, and the cable is used to transmit the electrical signal. The optical signal is transmitted through the optical fiber core and maintained in the optical fiber under the action of the optical fiber cladding and the optical fiber cladding. The electrical signal is transmitted through the copper wire in the cable. In the process of data transmission, the optical signal and the electrical signal are transmitted separately and do not interfere with each other.

　　Three, application field

　　Composite fiber optic cable combines the high speed, low latency of fiber optic transmission and the stability and reliability of cable transmission, and is widely used in communication networks in various fields. For example, it can be used for communication in power systems to achieve common transmission of power and communication signals; it can also be used for communication network construction in data centers, office buildings, etc., to provide high-speed and stable network support.

　　IV. Advantages and characteristics

　　高速传输：光纤具有极高的传输速率，能够满足大数据、云计算等应用对高带宽的需求。

　　稳定可靠：电缆的加入使得复合光缆在传输电信号时具有更高的稳定性和可靠性。

　　综合布线：复合光缆将光缆和电缆的功能融为一体，简化了布线工作，降低了布线成本。

　　抗干扰能力强：复合光缆的外部保护层具有耐磨、抗拉伸和防水等特性，能够有效抵抗外部环境的干扰。

　　In summary, composite optical cable is a communication cable that integrates the functions of optical fiber and cable. It has the advantages and characteristics of high-speed transmission, stability and reliability, comprehensive wiring, and strong anti-interference ability. With the advancement of science and technology and the increase in communication demand, composite optical cable will continue to play an important role in the future.
