The optical fibers will provide satisfactory service indefinitely if handled with normal care. Although the fibers are protected by a steel jacket, they can be damaged if the jacket is stretched, twisted, shocked or tightly bent to a small radius. The ends should be protected from damage, contaminants, and temperatures above 371°C (700°F). OMEGA does not warrant broken or damaged fibers due to mishandling.
