Precautions for using optical fiber bushing

Optical fiber bushing plays an important role in optical fiber communication system, and its usage precautions are directly related to the stability of optical fiber connection point and signal transmission quality. The following are precautions when using optical fiber bushing:

First, select the appropriate casing type

Select an appropriate casing based on the fiber type, connection mode, and application environment. Different types of casing have different characteristics and application scenarios. For example, heat shrink protection casing is suitable for applications requiring high strength protection, while V-slot elastic connection casing is suitable for applications requiring accurate alignment.

Second, ensure that optical fiber pretreatment is in place

Before using an optical fiber sleeve, ensure that the optical fiber has been adequately pretreated, including removing the coating layer, cleaning the optical fiber surface, and cutting the optical fiber accurately. These steps are essential to ensure the quality of fiber splicing and the effectiveness of the casing.

Third, correct operation of the welding machine

When welding optical fibers, strictly follow the operation instructions of the welding machine to ensure that the welding quality meets the requirements. At the same time, pay attention to avoid excessive stress on the optical fiber during the welding process, so as not to cause damage to the optical fiber.

Fourth, precautions in the casing application process

Casing length matching: The casing length should properly match the length of the optical fiber. Too long or too short may adversely affect the optical fiber. At the same time, when inserting the casing, ensure that the casing can completely cover the weld and have a certain overlap.

Avoid contamination: In the casing application process, pay attention to keep the fiber and casing clean to avoid pollution affecting its performance. In particular, the heat shrink protective casing should prevent impurities such as dust from entering the inside of the casing during the heating process.

Heating temperature control: For the heat shrink protective casing that needs to be heated, strictly control the heating temperature and time during the heating process to avoid burning the casing or damaging the optical fiber. At the same time, it is necessary to ensure that the air in the tube is completely removed and evenly heated to avoid the formation of bubbles during heat contraction.

Fixing and protection: After the heat shrink is completed, check the wrapping of the casing. If necessary, tape or other fixing devices can be used to fix the optical fiber at both ends of the casing to prevent it from moving or bending too much. At the same time, pay attention to avoid excessive bending or distortion of the unsheathed part of the optical fiber to avoid damage to the optical fiber.

Fifth, regular inspection and maintenance

Periodically check the status of the fiber sleeve, including whether it is aging, damaged, or loose. Discover the problem in time and take appropriate maintenance measures to prevent the problem from affecting the normal operation of the optical fiber communication system.

To sum up, the precautions for the use of optical fiber bushing involve many aspects, from selecting the appropriate bushing type to ensuring that the optical fiber pre-treatment is in place, to correctly operating the welding machine and the precautions during the application of the bushing, as well as regular inspection and maintenance, which need to pay enough attention to ensure the stability and reliability of the optical fiber communication system.
