Field-Installable Fusion Splice Connector

Yoshinori Iwashita; Serin Tan; Kazuhiro Takizawa; Noriyuki Kawanishi

Installing optical connectors in FTTx network usually involves field-installable connectors employing mechanical splices. Fujikura has developed a field-installable fusion splice connector that is easy to install and of high reliability.

Development of a sophisticated sub-micro fusion splicer for FTTP applications

Yoshinori Iwashita; Shigeru Saito; Tetsu Takashima

The installation of Japanese FTTP (fiber to the premise) networks often includes mechanical splices and optical fiber connectors to connect the drop cable to a premise or to connect an indoor cable within a premise. However, fusion splices are still the preferred method of connecting fiber at locations away from the premise. These remote locations include a variety of splicing environments such as aerial splicing that demand equipment portability and versatility. For these reasons, an increasing number of customers require an easy to use, smaller, and lighter splicer with a full set of features. To meet these customer requirements, the highest priority when we developed our new fusion splicer was that it would be the smallest, lightest, and most versatile in the industry.
