What step should be performed at the beginning of every fusion splicing operation?

The correct choice emphasizes the importance of ensuring optimal conditions for a successful fusion splicing operation. Performing test splices at the beginning of the process serves several crucial purposes. Firstly, it allows the technician to verify that the equipment is functioning correctly and that the splice loss is within acceptable limits. This step helps to identify any potential issues with the splicing machine or the fibers being used before actual work begins, thus minimizing the chances of failure during the main splicing process.

Conducting test splices can also provide valuable information about the characteristics of the fibers, such as their loss and reflection parameters, ensuring that they will perform well together. By having reliable test splice results, the technician gains confidence in the splicing setup, which is essential for maintaining the quality and reliability of the fiber optic network.

This approach stands in contrast to just organizing the workspace, which, while important for safety and efficiency, doesn’t address the technical readiness of the splicing operation. Similarly, calibrating tools without testing or assessing fiber quality afterward doesn’t provide the same immediate verification of the splicing process’s success or functionality, and conduct multiple test splices ensures thorough preparation.
