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

The profile alignment system utilizes a camera to align the optical fibers before splicing. In this method, the fibers are positioned based on their refractive index profiles, which are captured through imaging. This approach allows for precise alignment, ensuring that the cores of the optical fibers are optimally positioned relative to each other to minimize splice loss and maintain signal integrity.

This system differs from others like core alignment systems, which focus specifically on aligning the physical cores of the fibers without the aid of a camera. Active and passive alignment systems also have unique characteristics, but they do not rely on imaging for alignment like the profile alignment system does. Understanding this key distinction enriches comprehension of how various splicing methods can impact fiber optic performance and reliability.
