What mode should be used for fusion splicing multimode fiber
The fusion splicer automatically detects the fiber type, such as single-mode (SM), multimode (MM), or dispersion-shifted (DS) fibers, and adjusts parameters like arc power and heating time accordingly. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers. Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. Mechanical splicing means that two fiber ends are tightly held together with some mechanical means. That is usually done for permanent connections, but it may be possible to dismantle a splice without spoiling the fiber ends. In general, there are two main situations: Each case has its own challenges and solutions, which we'll explain.
