Which fusion splicer alignment method uses a camera to align the optical fibers before splicing?

The alignment method that utilizes a camera for aligning optical fibers before splicing is known as the PAS method, or the Passive Alignment System. This technique is characterized by its use of visual feedback to ensure that the fibers are precisely aligned, which is crucial for achieving low splice loss. The camera captures images of the fiber ends, allowing the technician to make fine adjustments to their position before permanently joining them.

This method stands out because it enhances accuracy through real-time imaging, making it easier to achieve optimal alignment compared to other methods that may rely on different alignment approaches. The emphasis on precision in the alignment process ultimately results in higher quality splices, which is particularly important in high-performance fiber optic networks.
