High-speed MT connector assembly method

This letter describes a high-speed mechanically transferable (MT) connector assembly method. The method uses adhesive with a short hardening time and high reliability, and does not require a polishing process. 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. We assembled an MT connector using our proposed high-speed assembly method. We confirmed that the assembly time could be reduced to less than 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.
