Different Types of Fiber Cables

  Underground fiber cable is specifically designed for installation below the surface, where it can be safely buried to protect it from environmental factors and physical damage. These cables are vital for telecommunications, data transmission, and network infrastructure, ensuring reliable connectivity over long distances. Types of Underground Fiber Cable: 1. Direct Burial Fiber Cable: Designed for direct placement into the ground without the need for additional protection like conduits. Features a rugged outer jacket and often includes water-blocking elements and armoring for protection against moisture, rodents, and other underground hazards. 2.Duct Fiber Cable: Installed within conduits or ducts that are buried underground. Offers added protection by being enclosed in a conduit, making it easier to replace or upgrade cables without excavation. Typically used in urban areas where cables need to be laid in complex underground networks 3.Aerial-to-Underground Transition Cable: Used where cables need to transition from aerial installations (e.g., on poles) to underground installations. Built to handle the mechanical stress of being hung and then buried. Key Features: Durability: Designed to withstand harsh underground conditions, including moisture, temperature changes, and pressure from soil. Water and Chemical Resistance: Often includes water-blocking compounds or gels and is resistant to chemicals found in soil. Rodent Protection: Some cables are armored or have protective layers to prevent damage from rodents. Ease of Installation: Designed for pulling through ducts or direct burial with minimal risk of damage. Applications: Telecommunications Networks: Ensuring reliable voice, data, and video transmission across large distances. ISP Networks: Connecting neighborhoods, cities, or regions with high-speed internet. Enterprise and Data Centers: Providing secure and high-capacity connections between facilities. Municipal Infrastructure: Used in smart city implementations for connecting traffic signals, surveillance systems, and public Wi-Fi. Considerations for Installation: Soil Conditions: The type of soil (rocky, sandy, etc.) will influence the choice of cable and the installation method. Depth of Burial: Must comply with local regulations and ensure the cable is protected from potential surface activities like digging. Environmental Factors: Consideration of factors like flooding, temperature extremes, and the presence of wildlife that might affect the cable’s longevity. Underground fiber cables are a critical component in modern communication networks, offering secure and reliable transmission in both urban and rural environments.

ASU optical cable--reduce the cost of operators' 5G network deployment

The cost of communication construction in many countries is related to the outer diameter and weight of the optical cable. The thicker the outer diameter of the optical cable, the greater the weight per unit length, and the higher the cost of using more materials, making operators charge more when renting pole roads. Therefore, a lightweight fiber optic cable design can save investment.   5G access network infrastructure expects lower costs     Global operators have generally performed speed-up and fee-reduction work, and 5G licenses have been issued. As 5G base stations are denser, expanding and building access networks is imperative. Reducing access network costs will vigorously promote the better and faster development of 5G.   The primary communication network of the access network consists of a large number of wiring segments and lines. 50m - 250m aerial optical cable with a small span is an essential part of the distribution line, among which the main force of self-supporting aerial optical cable is ADSS and '8' hanging wire cable. The cost of ADSS is relatively high, and the '8' hanging wire optical cable has safety hazards related to power lines or lightning due to metal components. The ASU optical cable produced by our company can solve these problems better. Compared with the conventional layered ADSS optical cable, the ASU optical cable can not only save the use of imported aramid yarn but also significantly reduce the manufacturing cost due to the reduction of the overall structure size: compared with the standard 150-meter span ADSS-24 optical cable, the price of ASU optical cable of the exact specification can be reduced by 20% or more; even compared with the most common overhead optical cable GYTS-24 optical cable, the price of ASU optical cable with the same number of cores is about 10% lower.       Ingenious cable construction and design make ASU cable lower cost.   ASU CABLE is the general abbreviation. This self-supporting single-cased aerial optical cable, the full name in Portuguese is Aéreos Auto-Sustentados Tubo único, began to rise in South America in 2016. Due to its simple structure, novel design, high-cost performance, and convenient construction, it has been widely used in America, Southeast Asia, Europe, and other regions.   Just like the butterfly optical cable designed in Japan, the ASU optical cable design concept also subtly combines the advantages of layer-stranded optical cable and central tube optical cable and combines the two into one. The core idea of the optical cable design is to use two rigid FRPs and a single loose tube to mix and twist, and the three-in-one steady-state twisting unit includes both the tensile element and the optical unit. Due to the existence of a specific pitch when twisting, the bendability of the optical cable is ensured. The fiber optic cable breaks through the existing standard and adopts a smaller outer sheath thickness, which makes the product lighter and suitable for self-supporting overhead use.     ASU optical cable has reliable performance guarantee.     The ASU optical cable design fully considers the aerial optical cable's mechanical and application environment requirements. Under the three-level meteorological conditions, the optical cable meets most application scenarios with a span of fewer than 250 meters. The two included FRPs have sufficient tensile strength and can resist sheath retraction and additional attenuation caused by temperature changes; reasonable cable core twisting pitch makes the optical cable easy to bend and coil; the optical cable structure is stable, compact. It also excels in other properties such as crush resistance, impact, torsion, etc., and meets the existing technical standards for outdoor overhead optical cables.   The ASU optical cable produced by our factory using the one-step method not only has high manufacturing efficiency and low cost but also the sheath and the cable core are closely bonded. The core pulling force of the optical cable is greater than 700N. There is a good grip between them to ensure no pull-off phenomenon. The product is especially suitable for the small span overhead of the access network distribution in urban and rural areas, and the commonly used span ranges from 50m to 250m.     In addition, the structure of ASU optical cable is compact and reasonable, and there will be no negative phenomena such as the standard arch bending of the '8' cable, the FRP head in the ADSS cable core, and the FRP breaking during construction. ASU fiber optic cables have been widely adopted in many countries such as Mexico, Chile, Vietnam, Thailand, Malaysia, Portugal, etc. ASU optical cable has stable performance and is well recognized and praised by users. It is especially suitable for construction in suburban, rural, or remote areas and can be directly laid along the existing pole road. Due to the excellent comprehensive performance of ASU optical cable, there are no special requirements for the selection of hanging hardware. The current splint type, pull ring type, and pre-twisted wire apply.
