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.
