What is the key focus during the termination of fiber optic cables?

The key focus during the termination of fiber optic cables is achieving a clean and polished end face. A well-polished end face is critical for ensuring optimal light transmission between fibers, as imperfections can cause significant signal loss. When the ends of the fibers are terminated, they must be cut and polished to a very fine finish to minimize reflection and scattering of the light signal. This cleanliness and precision help maintain the integrity of the connection, reducing potential dB loss that can arise from scratches or defects on the fiber surface.

In contrast, while minimizing the use of connectors, ensuring low splice loss, and using longer cables can be important aspects of a fiber optic installation, they do not directly address the immediate need for a clean and precise surface at the fiber ends during termination. A smooth, flawless end face is paramount to achieving effective connectivity and performance in a fiber optic network.
