What is a fiber optic cable and what does a fiber optic cable belong to?

The first floor is already very good, and I will add to it.

The personal summary definition of optical cable is as follows: that is, through special materials, artificially create total reflection conditions, so that a certain pattern of light propagates in it, so as to achieve the purpose of information transmission.

To understand fiber optic cables, you must first understand what fiber optics are, and these two concepts are often confused. At present, optical fibers are made of many materials, and the most commonly used optical fibers are generally referred to as quartz optical fibers (of course, there are other materials such as plastic optical fibers, glass optical fibers, etc.), and the optical fibers are cylindrical and composed of three parts: fiber core (common diameter, cladding (125um), coating layer (250um)).

The fiber core is mainly made of high-purity silica and a small amount of dopant to improve the optical refractive index of the fiber core, and the cladding is also high-purity silica and a small amount of dopant to reduce the optical refractive index of the cladding.

The coating layer is made of acrylic, silicone rubber, nylon, which increases mechanical strength and bendability.

The structure of quartz optical fiber, in principle, meets the above three material conditions, it can be called optical fiber, and the optical cable is based on the optical fiber to coat the protective layer or add protective elements to improve the mechanical properties, anti-aging performance, flame retardant performance, transmission performance, and so on to meet the specific transmission requirements. It can be understood that optical fiber is one of the important components of optical cable, and it is also a necessary condition for optical cable to guide light.

Without optical fiber, fiber optic cable is naturally not called fiber optic cable.

I've talked about it in enough detail, I hope it can help you.

Optical fiber cable (optical fiber cable) is mainly composed of optical fiber (thin glass filament as thin as hair) and plastic protective sleeve and plastic sheath, there is no gold, silver, copper and aluminum and other metals in the optical cable, and generally has no value. Optical cable is a communication line that a certain number of optical fibers are composed of a cable core in a certain way, covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission. Namely:

Cables formed by optical fibers (optical transmission carriers) through a certain process.

Optical cable belongs to the specialty of optical fiber communication. The optical fiber communication major cultivates application-oriented talents who can be engaged in the planning and construction of optical fiber network engineering, the commissioning and maintenance of SDH system, and the engineering maintenance of telecommunication core network and access network. Have strong ability in cable and optical cable design and construction, route planning and budget estimation, as well as comprehensive professional ability in the installation, commissioning and maintenance of optical fiber communication equipment and related fields.

The uses of fiber optic cables are:The main function of optical cable is optical signal transmission, which can meet the specifications of optical, mechanical and environmental performance, and is usually placed in one or more optical fibers wrapped in a sheath, and can be made into communication cable assemblies alone or in groups. It is made of optical fibers, plastic sheaths, and plastic outer layers, and is a kind of communication road for optical signal transmission.

Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fibers (glass filaments as thin as hair) and plastic protective sleeves and plastic sheaths, and there are no metals such as gold, silver, copper, and aluminum in the optical cable, and generally have no value. <

What is a fiber optic cable: A fiber optic cable is manufactured to meet optical, mechanical, or environmental performance specifications, and it is a communication cable assembly that utilizes one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. 1. The basic structure of the optical cable The basic structure of the optical cable is generally composed of several parts such as the cable core, the reinforcing core, the filler and the sheath, and the waterproof layer, buffer layer, insulated metal wire and other components as needed.

2. Classification of optical cables According to the different structures of optical cables and different use scenarios, Hangzhou Corning Optical Cable is divided into three series, namely special optical cable product series, indoor optical cable product series, and outdoor optical cable product series.

Optical cable is a kind of cable used to transmit optical signals, which is mainly composed of a fiber core, a plastic protective sleeve and a plastic sheath.

Fiber optic cables are manufactured to meet optical, mechanical, or environmental performance specifications, primarily for the transmission of optical signals, and consist of two or more glass or plastic fiber cores that are located within a protective cladding and covered by a plastic PVC outer sleeve. At present, indoor field optical cables are mainly used for outdoor direct burial, pipeline, overhead and underwater laying optical cables; Indoor optical cable is used for indoor deployment of optical cable.

The optical cable realizes the optical signal transmission is to turn the information to be transmitted into an electrical signal at the transmitting end, and then emit it to the laser beam through the laser, the intensity of the light will change with the frequency of the electrical signal, and it is emitted through the optical fiber, at the receiving end, the detector receives the optical signal and turns it into an electrical signal, and the original information is restored after processing.

Advantages of fiber optic cable transmission

The frequency bandwidth of the optical fiber transmission system is more than a few hundred megahertz for multi-mode optical fiber, and the bandwidth of single-mode optical fiber can reach more than ten gigahertz, and dozens or hundreds of TV signals can be transmitted through one optical fiber. Since optical fiber transmission generally does not require relay amplification, it does not increase noise and introduce nonlinear distortion, and the signal can be transmitted with high fidelity as long as the laser linearity is good.

The material used to make the optical fiber is Shiyuan Rangying, and the signal transmitted in it is an optical signal, so the optical fiber transmission is not interfered by external electromagnetic waves and lightning. Because the optical fiber is very light and thin, it has the characteristics of small diameter and light weight after being made into optical cable, and the bending radius of the optical cable is small, corrosion resistance, not afraid of moisture, and the temperature coefficient is small, and the laying of optical fiber cable is also more convenient.
