The splicing environment must be kept as _____ as possible.

The splicing environment must be kept as clean as possible because contaminants like dust, dirt, or moisture can negatively impact the quality of the splice. Fiber optic splicing requires precision, and even small particles can cause interference or loss in signal strength. A clean environment minimizes the risk of splicing defects that could lead to increased attenuation and decreased performance of the fiber optic cable. Maintaining cleanliness is critical for ensuring optimal connections and the overall reliability of the fiber optic network. By focusing on cleanliness, technicians can achieve better results and maintain the integrity of the fiber optic installation.
