First of all I'm delighted to highlight that the abbreviation of our company name, being the Doin', stands for "Doing" which reflects the meaning that we should try to keep going more valuable work than ever before so that we can lead our daily life more enriched and pleasant.

This basic theory is linked to our company's business philosophy which reads saying "Let's make our daily life more convenient with creating value added through using the photoelectrical technology"

The scope of our company business at present lies in the field of the Fiber Optical Product Technologies? Photoelectrical Conversion, Optical Amplification, Photoelectrical system and Control Program Technology and so forth, and in the near in the future, we will be launching info the field of Living Photoelectrical Technology, Optical Fiber Technology and Professional Technical Education Technology.

Doin' Corporation was founded in March 1995 with the company goal to become a world famous optical technology enterprise, and since 2000 we have been producing various types of Optical Fiber Components and Fiber Optical Coupler fabrication equipment & Fiber Optic Cables. And as for the Fiber Optical components, we are producing both types of the Single Mode and Multi mode Couplers and Wavelength Division Multiplexer (WDM).
