VI Systems is a fabless developer and producer of optical engines for data transmission at ultrahigh bit rates and the related electro-optic components for applications in datacommunications and access networks. The concept of the company is vertical integration to achieve qualitatively new functionality. This addresses both the design of electro-optic components and the vertical integration of them into a value chain bringing a universal optical engine, which can be further complemented by advanced coding schemes for digital and analog optical transmission.VIS is planning to reach bit rates above 100 Gb/s per channel in the near future at low cost and power consumption.
