Method of making a coated optical fiber comprising measuring the delamination resistance of the coating at two different temperatures

摘要

Making a polymer-clad optical fiber comprising a step of determining at a plurality of temperatures the delamination resistance of the polymer coating from fiber. The delamination resistance at ambient temperature can be compared with a predetermined target value for delamination resistance in use. The delamination resistance at elevated temperature can be compared with a predetermined lower target value for ease of strippability. Coated optical fiber having delamination resistances outside the predetermined ranges will typically be rejected.
