With increasing demand for higher wireless data transmission speeds and capacities, the search is on for ways to use high-frequency terahertz (THz) waves that have a much larger capacity to carry data.
The French research laboratory IEMN used Tektronix instrumentation to demonstrate a single carrier wireless link traveling at a 100 Gb/s data rate. This demonstration uses advanced data coding, THz photonics and wideband and linear devices to enable ultra-fast wireless connections in the 252 – 325 GHz band per the recently published IEEE 802.15.3d standard.
The new 802.15.3d standard & its applications
The purpose of the new 802.15.3d standard is to provide for low complexity, low cost, low power consumption, very high data rate wireless connectivity among devices and in the future ‘low THz’ bands. Potential applications include consumer multimedia, wireless switched point-to-point applications in data centers, wireless backhaul/front haul, intra-device communications and a wide variety of additional use cases such as rapid large multimedia data downloads and file exchanges between two devices in close proximity.
“Tektronix is delighted to be working in such close collaboration with IEMN on achieving this prestigious breakthrough,” said Dr. Klaus Engenhardt, CTO Tektronix EMEA. “It’s exciting to see our industry-leading end-to-end transmit and receive solution used to help bridge coherent optical and THz transceiver technologies. Advanced test tools are needed today to generate and characterize signals at 100G, 400G and beyond and Tektronix offers a wide portfolio of optical communication test solutions.”
“Achieving 100 Gb/s transmission in a single carrier helps to fill the gap between the worlds of fiber-optics and radio. By combining the concept with dedicated architectures and photonic-based THz circuits we are paving the way for faster wireless transmission than what’s possible today,” said Guillaume Ducournau, an associate professor at IEMN/CNRS/University Lille working on THz communication systems.
The Tektronix test equipment used in the IEMN demonstration included an AWG70000 Series 50GS/s arbitrary waveform generator, DPO70000SX 70GHz oscilloscopes and an OM5110 46GBd coherent optical transmitter.
