Novel Field Installable Sagged Fiber Connector Realizing Physical Contact Connection without Polishing Fiber Endface
We propose and demonstrate a new type of field installable optical fiber connector that enables us to realize physical contact connection by using a sharpened fiber endface and the compression force of sagged fiber.
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.
Hole-assisted fiber design for small bending and splice losses
This letter describes the bending and splice loss characteristics of hole-assisted fibers and reveals that the distance between the hole and the fiber core is a key parameter regarding these losses. We found that the normalized hole distance against the core radius must be two or greater for practical deployment.
