^7fThis paper describes a high-speed MT connector assembly method. The method uses adhesive with a short hardening time and high reliability, and that does not require a polishing process, thus reducing connector assembly time. First, we investigated an alpha-cyanoacrylate adhesive that hardens quickly and whose adhesive strength does not decrease under high humidity and high temperature conditions thus ensuring its high reliability for outside use. In addition, we investigated variations in the position of the fiber endface on the ferrule endface with a view to obtaining a low insertion loss. Based on the results, we assembled an MT connector using our proposed high-speed assembly method. We confirmed that the assembly time could be reduced to less than 60%～70% of the time required with the conventional assembly method. The MT connectors assembled using this method have a low insertion loss and stable environmental characteristics.
