After the fiber splicing, the light transmitted to the optical fiber splice joints will have a certain amount of loss, called splice loss. Optical fiber splice loss is mainly composed of an optical fiber transmission loss and splice loss itself constituted. As the quality of fiber optic splice fiber-optic lines will result in transmission loss, optical line transmission distance and other factors, therefore, to minimize fiber optic fusion splice loss, in order to ensure the transmission quality of the fiber CATV signals.

So, how to reduce the fiber optic fusion splice loss?

1, try to use the same batch of high-quality brand-name bare fiber on one line;
2. In accordance with the requirements of optical fiber cable erection;
3. Select the experienced, well-trained personnel to optical fiber splicing;
4. splice fiber optic cable should be carried out in clean environment;
5. The selection of high accuracy fiber end face cutter to prepare a fiber end face;
6. The proper use of welding machine.
