Fujitsu Develops All-Plastic Ferrule for Optical Connectors
Sunnyvale, Calif. - January 28, 2003 - - Fujitsu Component Ltd. (Head Office: Shinagawa-ku, Tokyo; Capital: 2764 Million Yen; President: Tozo Ono] and Fujitsu Laboratory Ltd. [Head Office: Nakahara-ku, Kawasaki City; Capital: 5 Billion Yen; President: Michio Fujisaki] have jointly developed a process for mass-producing inexpensive, all-plastic ferrules with high strength, high durability and optical characteristics equivalent to
traditional Zirconia ferrules.

Based on this development, Fujitsu Component will promote the development and commercialization of optical devices with this
technology as the core.
A ferrule is a component that guides optical fibers in optical connectors.
It requires extremely high precision (circularity: 1 µm max., external diameter: 1 µm max., concentricity: 1.4 µm max.) to accurately
join the optical fibers.
Traditionally, ferrules are made of Zirconia ceramic and the end faces must be polished prior
to use. Using an all-plastic material saves labor cost required for this polishing process.
Developing a plastic ferrule with precise, mechanical dimensions requires uniform, thin walls, which makes mass production difficult because strength and durability cannot be assured. Fujitsu Component, however, was able to make the ferrule walls sufficiently thick enough to assure mechanical strength by using an injection molding process based on its own precision die and molding technology and a proprietary
plastic developed by Fujitsu Labs.
