Paper Abstract

A serious concern in the fiber optics industry is the low strength of fiber in connectors, frequently as low as 10% of that of the original fiber. The main reason for this low strength is that the stripping and termination procedure exposes and abrades the bare glass surface. Several fiber manufacturers have recently introduced a fiber construction which can greatly improve the mechanical reliability of fiber in connectors. The actual constructions from the various manufacturers vary in detail, but all have one common feature, a primary organic coating which remains in place when the secondary coatings are removed in preparation for terminating the fiber into a connector. In order for connectors to be successfully glued to this coating, the coating must be hard and well adhered to the glass surface. The coating is generally thin, typically about 10 pm. With such a coating the bare glass surface is never exposed when the fiber is stripped and terminated, and thereby retains its strength and mechanical reliability. Data will be presented on the strength of terminated fiber with and without such permanent, primary coatings.
