As part of a NEDO project, the Photonics Electronics Technology Research Association (PETRA) and Fujitsu Limited have developed a compact, high-capacity optical transceiver technology. Using this technology, the team developed a new silicon photonics optical transceiver, which operates at approximately 400 Gbps/cm2, the world's highest transmission density and roughly double that of previous technology. Furthermore, the team has developed an optical modulation transmission technology for generating high-speed optical signals with four-level pulse control. This advance has made it possible to transmit data at with 40% less power consumption than before at high speeds of one-channel, 56 Gbps.

These results are expected to greatly contribute to a significant improvement of server processing speeds.

The details of this technology were first announced at the European Conference on Optical Communication 2017 (ECOC 2017), an international conference held in Gothenburg, Sweden from September 17 through 21.
