Optical fiber switching device having one of a robot mechanism and an optical fiber length adjustment unit

There is disclosed an optical fiber switching device having a coupling board comprising a plurality of first optical fibers connected to one surface of the coupling board in the arrangement to one surface of the coupling board, a plurality of second optical fibers connected to the another surface of the coupling board, an optical fiber length adjusting unit for handling surplus portions of the second optical fibers and switching unit for pulling out any one of the second optical fibers selected from the plural second optical fibers from the another surface of the connecting board and for connecting the any one optical fiber to different switching position of the another surface of the connecting board to coupling the any one optical fiber with any one of the first optical fibers.

A novel optoelectronic ferrule and easy ribbon fiber splicer for cost-effective optical interconnection

Attention has turned in recent years to optical interconnection as the most cost-effective solution to the problem of I/O bottlenecks in the wiring of conventional FR4 printed wiring boards. In this paper we propose a new configuration for the key element in realizing optical interconnections, a low-cost electrical/optical (E/O) converter module. We furthermore propose an easy splicer and a ribbonized coated-mountable fiber for multicore optical interconnections.

A Novel Optoelectronic Ferrule for Cost-effective Optical Interconnection Modules

We developed an optoelectronic ferrule using hoop injection molding. By mounting a vertical cavity surface emitting laser (VCSEL) (or photo diode (PD)) directly on the end-face of the ferrule, an extremely simple and cost-effective optical interconnection module can be created.
