    摘要: The present invention relates to an adhesive for connecting and fixing an optical fiber to an optical connector and to an optical connector which uses that adhesive. The adhesive prevents deformation of the optical connector ferrule and stressing of the optical fiber due to hardening shrinkage during the hardening of the adhesive and/or a shrinkage during cooling of the adhesive. In accordance with the invention, (1) the value of (the coefficient of linear expansion (.degree.C..sup.-1) of the adhesive).times.(the difference between a hardening temperature of the adhesive and room temperature (.degree.C.)).times.(Young's Modulus (kg/mm.sup.2) of the adhesive) is equal to or less than about 2.5, (2) the value of (the rate of hardening shrinkage (%) of the adhesive).times.(Young's Modulus (kg/mm.sup.2) of the adhesive) is equal to or less than about 1000 and/or (3) the adhesive hardens at room temperature.

    摘要: A novel optical connector that includes the following: an optical connector ferrule which is capable of fixing optical fibers; optical fibers fixed onto the optical connector ferrule, such that the end surfaces of the optical fibers project beyond an end surface of the optical connector ferrule; an adhesive for fixing the optical fibers onto the optical connector ferrule; and a member whose Young's Modulus is less than that of the optical fiber and is provided to an area on the end surface of the optical connector ferrule surrounding, at a minimum, the projected portions of the optical fibers. And when the end surface of the optical connector is polished, the ends of the optical fibers are capable of projecting from the end surface of the optical connector ferrule, even if the end surface portion of the optical connector ferrule contains a filler, the hardness of which is less than that of the optical fibers.
