United States : USB 3.0 to get 10Gb/s transfer rate

June 19, 2014

With a view to transfer large amounts of data from one terminal device to another in next to no time and without an interfering cable, researchers at the Fraunhofer Institute for Photonic Microsystems (IPMS) are working on using light as a transmission medium. Optical wireless data transmission should serve as an alternative to wired data transfer and replace established standards such as USB3.0, USB3.1, Gigabit-Ethernet or 10-Gigabit-Ethernet.

Dr. Frank Deicke, group manager for optical sensors and data transmission at Fraunhofer IPMS, made an optical wireless communications module at the end of 2013 that enabled a data transfer rate of up to 5 gigabits per second (Gb/s). He has now succeeded in doubling this rate. Deicke and his team developed a transceiver for optical wireless communications that is no larger than a sugar cube and that can transfer data via infrared (IR) at up to 10 Gb/s. Compared to familiar radio technologies such as Bluetooth or wireless local area network (WLAN), this communications module has a higher data throughput, a low bit error rate and saves more energy (power consumption of estimately 100 milliwatts (mW) at 10Gb/s). Mobile, battery-operated devices such as smart phones or digital cameras with only a low battery life in particular profit from this latter feature.

The transceiver will be used in the consumer sector and for industrial applications, wherever large amounts of data have to be transferred from one terminal device to another, for example, in automation, safety and process control or medical technology.

The Fraunhofer IPMS offers various evaluation kits that give interested parties the opportunity to evaluate an optical wireless data transfer with data rates of up to 1 Gb/s, 5 Gb/s or 10 Gb/s in their target systems. The performance and size of the transceiver can be adapted to customer-specific needs.
