Advantages and disadvantages of fiber optic fusion splicing
The advantages of fusion splicing include consistent quality and low insertion loss (approximately 0. However, the equipment cost is high, and the battery life of the splicer is limited, restricting its use in field operations. Fiber optic splicing is the process of joining two fiber optic cables together so that light signals can pass with minimal loss or reflection. Splices are permanent joints, while connectors allow the two fibers to be connected and disconnected. In summary,mechanical fiber fusion splicing is preferred for large-scale applications requiring high precision and efficiency, while manual fiber fusion splicing offers flexibility and lower costs, making it suitable for smaller or more complex projects. Mechanical splicing introduces unavoidable compromises: For networks requiring stable performance over many years, these factors must be carefully considered.
