A method of making a fiber optic connector sub-assembly involves: initially disposing a bonding agent in a ferrule bore of a ferrule; heating at least a portion of the ferrule above a melting temperature of the bonding agent so that some of the bonding agent melts; and solidifying the bonding agent that has melted to form the fiber optic connector sub-assembly, all without an optical fiber being disposed within the ferrule bore.

A fiber optic connector sub-assembly includes a ferrule having a front end, a rear end, and a ferrule bore extending between the front and rear ends along a longitudinal axis. The fiber optic connector sub-assembly also includes a bonding agent disposed in the ferrule bore and having first and second ends along the longitudinal axis. The bonding agent has been melted and solidified at the first and second ends.

A curable composition includesa first component containing aldehyde group-containing compounds which include at least one compound with two or more aldehyde groups anda second component containing 1,3 keto ester group-containing compounds which include at least one compound with two or more 1,3 keto ester groups of the formula (I), wherein the average molecular weight M.sub.n of at least one of the two components, with respect to the aldehyde or 1,3 keto ester group-containing compounds, ranges from 400 to 20,000 g/mol. The composition is largely free of toxic ingredients and cures in ambient conditions using conventional catalysts quickly in order to form a non-tacky elastic polymer with a high degree of strength and elasticity. The composition is particularly suitable for use as an elastic adhesive, sealant, or coating with a high degree of robustness during production, storage, and processing as well as a high degree of resistance after curing.
