The long-distance capacity of 24-core optical cable

　　The long-range ability of a 24-core cable mainly depends on its tranSMission mode and fiber specifications. Here is a detailed analysis of the long-range ability of a 24-core cable:

　　First, the transmission mode

　　single mode cable

　　Transmission distance: Single-mode optical cable has a long transmission distance and is suitable for long-distance communication. Its transmission distance can reach tens or even hundreds of kilometers, depending on the attenuation of the optical signal and the use of the optical amplifier.

　　Fiber Specifications: The inner diameter of a single-mode cable is usually 9 micrometers and the outer diameter is 125 micrometers.

　　Multimode cable

　　Transmission distance: The transmission distance of multimode optical cable is relatively short, usually limited to less than 2000 meters. This is because the optical signal in the multimode optical cable will be reflected multiple times inside the fiber, resulting in faster signal attenuation.

　　Fiber Specifications: There are two specifications for multimode fiber optic cables, with an inner diameter of 62.5 μm and 50 μm, and an outer diameter of 125 μm. Currently, multimode fiber optic cables with an inner diameter of 50 μm are more common.

　　Second, the ability to pull long distances in practical applications

　　In practical applications, the long-range ability of a 24-core cable is also affected by the following factors:

Fiber loss: Fiber will experience loss during transmission, including absorption loss, scattering loss, and bending loss. These losses will cause the attenuation of the optical signal, thus affecting the transmission distance.

Optical amplifier: In long-distance transmission, it may be necessary to use an optical amplifier to enhance the strength of the optical signal to overcome the fiber loss. The use of optical amplifiers can extend the transmission distance of optical cables.

Connectors and joints: The connectors and joints between optical cables will also introduce losses. If the connectors and joints are of poor quality or improperly installed, additional losses will occur, thus affecting the transmission distance.

Environmental factors: Environmental factors such as temperature, humidity, and vibration will also affect the transmission performance of optical cables. For example, high temperature will cause the fiber material to expand, thereby increasing the loss; excessive humidity may cause water vapor to adhere to the surface of the optical fiber, increasing the scattering loss.

　　III. Recommendations

　　In order to ensure the optimum long-distance capacity of the 24-core cable, the following measures are recommended:

Choose high-quality optical cables: Choose optical cables with high transmission rates and low losses to ensure stable signal transmission.

Use high-quality connectors and joints: Ensure that the connectors and joints are of good quality and installed correctly to reduce additional losses.

Plan the optical cable path reasonably: Avoid excessive bending or mechanical damage to the optical cable to reduce bending loss and loss caused by physical damage.

Maintain the optical cable regularly: Regularly inspect and maintain the optical cable to detect and solve problems in a timely manner to ensure the normal operation of the optical cable.

　　In summary, the long-range ability of a 24-core fiber optic cable depends on its transmission mode and fiber specifications, as well as factors such as fiber loss, optical amplifiers, connectors and splices, and environmental factors. In order to ensure the best transmission performance of the fiber optic cable, it is necessary to choose high-quality fiber optic cables and connecting devices, and plan the fiber optic cable path and perform regular maintenance.
