Zhongtian Optical Cable The manufacturer believes that the power system communication network is one of China’s largest and most well-developed private networks. With the accelerating trend toward fiber-optic communication networks, the power industry’s dedicated communication network in many regions has essentially completed its transition from trunk networks to access networks and ultimately to fiber-optic infrastructure. Currently, the primary services carried over the power system’s fiber-optic communication network include conventional telecommunications services such as voice, data, broadband services, and IP; while specialized power-generation applications encompass protection and security automation devices, as well as broadband data required for electricity market operations. In particular, protection and security automation devices place even higher demands on the reliability and safety of optical cables. It can thus be said that fiber-optic communication has become an indispensable and critical component for the safe and stable operation of the power system, as well as for its production and daily operations.

　　1. Optical cables are typically very long. According to Zhongtian Optical Cable Manufacturer, the standard manufacturing length for optical cables is 2 kilometers. During cable installation, avoid cutting the cable or adding extra splices unless absolutely necessary.

　　2. Optical cables have limited tensile strength. According to Zhongtian Optical Cable Manufacturer, when the tensile force on the optical fiber exceeds its ultimate tensile strength, the fiber will break. To enhance the cable’s tensile performance, reinforcing members are incorporated into the cable structure, and these members bear the primary responsibility for meeting the cable’s required tensile strength. During installation, the pulling force must not exceed the cable’s specified allowable rating, and efforts should be made to minimize tensile strain on the optical fiber. The allowable pulling force for optical cables varies depending on the manufacturing process; this should be carefully observed during installation. Typically, the tension resistance of standard optical cables ranges from 100 to 300 kilograms.

　　3. Small cable diameter and light weight

　　4. Fiber-optic connection technology has high requirements and is complex to implement.

　　5. According to Zhongtian Optical Cable Manufacturer, fiber-optic splicing requires melting the fiber end faces at high temperatures and then using the viscosity of quartz glass to bond them together. Consequently, the equipment required for splicing is more complex, and the technical requirements are higher.

　　Zhongtian Optical Cable Manufacturer believes that fiber attenuation is the primary factor affecting optical transmission. In fact, there are many intricate details involved. The main factors contributing to fiber attenuation include intrinsic loss, bending, compression, and impurities. Take compression as an example: once a fiber is subjected to compression, it will experience slight bend-induced loss. Only by thoroughly understanding the causes of fiber attenuation and the characteristics of optical cables can we make better use of optical communication. The principal factors leading to fiber attenuation are: intrinsic loss, bending, compression, impurities, non-uniformity, and splicing.

　　1. According to Zhongtian Optical Cable Manufacturer, intrinsic loss refers to the inherent attenuation of optical fiber, including Rayleigh scattering and intrinsic absorption.

　　2. Bending: When an optical fiber is bent, some of the light within the fiber is lost due to scattering, resulting in insertion loss.

　　3. Zhongtian Optical Cable Manufacturer believes that compression: when the optical fiber is subjected to compression, it bends slightly, resulting in signal loss.

　　4. Impurities: Impurities in the optical fiber absorb and scatter the light propagating through it, resulting in loss.

　　5. According to Zhongtian Optical Cable Manufacturer, non-uniform refractive index leads to non-uniform fiber material loss.

　　6. Zhongtian Optical Cable The manufacturer attributes the insertion loss in fiber-optic splicing to factors such as misalignment (with single-mode fibers requiring coaxiality better than 0.8 µm), non-perpendicular end faces, surface irregularities, mismatched core diameters, and poor fusion-splicing quality.
