Which is better pre-fabricated optical cable or in-situ fused optical cable
Both have their strengths and weaknesses, but we find pre-terminated cable is almost always the best choice. Each method impacts cost, installation time, and performance, and choosing the right one ensures both efficiency and reliability. In this article, I will break down the differences between pre-terminated and field-terminated fiber. Termination of fiber optic cable may be done in two main ways: through connector termination or fo cable splicing (more commonly known as fo cable splicing).
