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

The initial step at the beginning of every fusion splicing operation is critical for ensuring high-quality splices and effective performance of the fiber optic network. Making multiple test splices to verify settings is essential because it allows the technician to adjust and fine-tune the splicing machine's parameters to achieve optimal results. This step confirms that the equipment is functioning correctly and that the settings are appropriate for the specific type of fibers being joined.

By performing test splices, technicians can identify any potential issues or inconsistencies in the splicing process upfront. This practice leads to a higher success rate in achieving low splice loss and maintaining the integrity of the fiber optics. Once the settings are verified, the technician can proceed with confidence, knowing that the equipment is properly calibrated for the job at hand.

Gathering all required tools and materials, calibrating optical fibers, and cleaning the workspace are indeed important steps in the preparation process, but the specific act of making test splices is paramount to ensuring that the initial conditions of the splicing operation are optimal for achieving the desired performance outcomes.
