Basic structure and classification of optical fiber cable
I will introduce the basic structure and various main types of optical fiber cable in more detail:
Basic structure of optical fiber cable:
- Optical fiber core (Core): Made of high-purity quartz glass or plastic, with a diameter of generally 8-50 microns, used to carry the transmission of optical signals.
- Optical fiber cladding (Cladding): Located on the periphery of the optical fiber core, made of low-refractive index glass or plastic of the same material, with a thickness of about 125 microns. It plays the role of an optical waveguide, allowing the optical signal to be reflected and propagated inside the optical fiber core.
- Buffer (Buffer): Wrapped outside the optical fiber cladding, usually made of plastic material, with a thickness of about 0.25-0.9 mm. Used to isolate the external environment and protect the optical fiber core and cladding from mechanical damage, moisture, chemical corrosion, etc.
- Strengthening Layer: Located outside the buffer layer, it is woven from steel wire, aramid fiber or glass fiber. It provides mechanical strength to prevent external forces from damaging the optical fiber.
- Jacket: The outermost protective layer, usually made of polyethylene, polyvinyl chloride and other materials, with a thickness of about 0.5-3 mm. It is used to prevent the optical fiber cable from being stretched, squeezed, cut, corroded and other external damage.
Main categories of optical fiber cables:
- Single-Mode Fiber Cable: The optical fiber core has a small diameter and only supports one transmission mode. It is suitable for long-distance, high-speed transmission, such as trunk networks.
- Multi-Mode Fiber Cable: The optical fiber core has a large diameter and can support multiple transmission modes. It is suitable for short-distance, low-speed transmission, such as local area networks.
- Dual-core fiber optic cable: contains two independent optical fiber cores, which can realize two-way communication or backup transmission.
- Multi-core fiber optic cable: consists of multiple (usually 4, 8, 12 or 24) independent optical fiber cores, used for large-capacity and high-density transmission.
- Optical cable: formed by bundling multiple optical fiber cables (such as single-mode or multi-mode), suitable for large-capacity and long-distance optical fiber communication networks.
The above is an introduction to the basic structure and main classification of optical fiber cables. The appropriate type of optical fiber cable will be selected in different application scenarios to meet the requirements of transmission rate, distance, capacity, etc.
Features of Ribbon Fiber Cable
Let me introduce you to the features of ribbon fiber cable in detail:
Physical structure and manufacturing process of ribbon fiber cable:
- Ribbon fiber cable is composed of multiple small optical fibers arranged in parallel, presenting a flat ribbon appearance.
- Each optical fiber has an independent core, cladding and buffer layer, arranged side by side in a common outer sheath.
- During the manufacturing process, multiple pre-processed optical fibers are first arranged side by side and then uniformly coated in an outer sheath. This manufacturing process makes the ribbon cable highly consistent.
Advantages of ribbon fiber cable:
- High density: Because the optical fibers are arranged side by side, ribbon cables can accommodate more optical fibers under the same cross-sectional area. This enables it to transmit higher information capacity in a limited space.
- Flexibility: Compared with round fiber optic cables, ribbon cables have stronger bendability and flexibility. This feature makes it easier to install in narrow or curved spaces.
- Space saving: The flat structure makes ribbon fiber optic cables take up less space when wiring, which is conducive to cable management and wiring.
- Easy to identify: Due to the flat shape, ribbon cables are easier to identify and distinguish in complex cable environments.
- Good compatibility: Ribbon cables are well compatible with various standard interfaces and devices.
In short, ribbon fiber optic cables rely on their unique physical structure and manufacturing process, showing obvious advantages in density, flexibility, space utilization, etc., and are more advantageous in some specific application scenarios.
Main application scenarios of ribbon fiber optic cables
Let me introduce you to the main application scenarios of ribbon fiber optic cables in detail:
Data center applications:
- The wiring environment inside the data center is very complex, with narrow space and high density requirements.

Main points for installation and wiring of ribbon fiber cables:
- Check whether the cable surface is damaged and ensure that the cable is intact before installation.
- Plan the cable routing path and try to avoid excessive bending or stretching.
- Use a dedicated fiber stripping tool to carefully strip the outer sheath to expose the inner fiber core.
- Terminate the stripped fiber to the optical connector, and clean and weld it carefully.
- Use appropriate fixing methods, such as cable ties, plastic card slots, etc., to prevent the cable from hanging in the air.
- For areas that need to be inserted into pipes or enter narrow spaces, a dedicated fiber introduction tool can be used.
- Organize the cable lines and clearly mark the corresponding relationship between the fiber ports.
Regular inspection and maintenance treatment suggestions:
- Perform a comprehensive inspection of the cable every quarter to check for mechanical damage, bending deformation, etc.
- Check whether the fiber connector is contaminated or damaged, and clean or re-weld it if necessary.
- Monitor the fiber transmission performance, such as power loss, etc., and promptly detect and handle abnormal conditions.
- Keep the cable routing neat and orderly to avoid being squeezed or pulled by other equipment or objects.
- For cables exposed to harsh environments, they should also be regularly checked for moisture or corrosion.
- For cables that have been used for a long time, partial replacement may be considered to improve reliability.
In summary, the correct installation and effective maintenance of ribbon fiber cables are essential to ensure their long-term stable operation. By following relevant operating procedures, its advantages can be maximized.
