ABSTRACT:
A coated optical fiber (30) includes optical glass fiber which has been drawn from a preform and provided with one or more layers of coating materials having defined properties. The layer (32) of coating material which is contiguous to the drawn glass fiber may be one which in a preferred embodiment is cationically cured coating material. Curing of the cationically cured coating material causes an acid to be generated. The acid which has a relatively long life is effective to reduce sufficientlythe pH of the environment in contact with the drawn glass to cause the coated optical fiber to have enhanced mechanical strength.
