Fiber Optic Splicing Techniques: Essential Skills for Ensuring Connection Quality

Fiber optic splicing is a key link in optical cable construction and maintenance, directly affecting the transmission performance and stability of the optical network. Poor splicing quality can lead to increased signal attenuation, frequent network interruptions, and other problems. Mastering standard splicing techniques and quality control methods is essential for every optical cable engineer. There are two main types of fiber optic splicing: fusion splicing and mechanical splicing, each with its own applicable scenarios.

Fusion splicing is widely used in long-distance and high-reliability scenarios due to its low loss and high stability. The key steps include fiber stripping, cleaning, cutting, and fusion. It is crucial to ensure that the fiber endface is clean and flat; any contamination or damage will affect the splicing effect. Mechanical splicing is suitable for emergency repairs and short-distance connections, with the advantages of fast construction and simple operation, but the loss is slightly higher. Regardless of the splicing method, post-splicing testing is indispensable. Using an OTDR to detect the splicing loss and ensuring it is within the standard range can effectively prevent subsequent faults. In addition, proper protection of the splice joint, such as using a high-quality splice closure, is necessary to avoid damage from moisture and external forces.

The quality of fiber optic splicing depends on standard operating procedures and strict quality control. Only by paying attention to every detail can we ensure the reliable operation of the optical network.
