PETRA has completed the following projects.
- Research and Development of High Speed and Low Power Data Transfer System Using Photonic and Electronic Hybrid Switch for Next Generation Datacenter with Disaggregation Architecture
By innovating hybrid system of photonic and electronic switch, we target significantly reducing power consumption of ultra-wide-band network connecting separated functions such as a processor and a memory in the next generation datacenter with disaggregation architecture.
More specifically, we are developing element technologies and components, such as a control system of photonic and electrical switch, photonic ToR switch consisting of an optical wavelength transceiver capable of transmitting and receiving intermittent burst-like optical signals incorporating a burst multi-level processor, a photonic core switch. Then we demonstrate the hybrid switching system of photonic and electronic switch with developed elemental technologies and components.
