Methods and compositions for the surface treatment of ferrules and fibers for improved bonding of optical fibes within ferrules

A method for bonding an optical fiber within a fiber opening of a ferrule using an adhesive, the method comprising:

• initiating curing of a first portion of the adhesive via a chemical cure initiator and initiating curing of a second portion of the adhesive via a radical cure initiator.

A method of adhering an optical fiber in a ferrule, comprising:

• providing an adhesion promotor at an interface between the optical fiber and the ferrule, the adhesion promotor;
• and
• securing the fiber within the fiber opening via an adhesive composition comprising a monomeric precursor of a methylene malonate polymer that is polymerized by a chemical initiator and a radical cure initiator when the optical fiber is inserted into the ferrule.
