The SAFARI project (coordinated by Prof. Toshio Morioka, DTU Fotonik and Dr. Yutaka Miyamoto, Nippon Telegraph and Telephone Corporation (NTT), Japan) has demonstrated ultra-large capacity inline optical amplified transmission of 1 petabit per second (Pbit/s) over a 205.6 km length of 32-core optical fiber.
The demonstration was carried out in collaboration with NTT, Japan, Fujikura Ltd., Japan, Hokkaido University, Japan, the University of Southampton, UK, and Coriant GmbH, Germany.
This sets a new world record in transmission distance of one Pbit/s capacity over a single strand of optical fiber within only a single optical amplifier bandwidth (C-band). The present accomplishment also indicates that one Pbit/s transmission systems over 1000 km are potentially possible, enabling us to connect major cities both in Europe and in Japan with one Pbit/s capacity over a single optical fiber.
“The capacity will be around 100 times that of the present systems and the breakthrough in transmission distance can have a huge impact on the construction of future optical networks,” Prof. Morioka explains.
Part of this research was based on results from the EU-Japan coordinated R&D project on “Scalable And Flexible optical Architecture for Reconfigurable Infrastructure (SAFARI)”commissioned by the Ministry of Internal Affairs and Communications (MIC) of Japan and EU Horizon 2020.
The groundbreaking demonstration was presented as a post deadline paper at the Optical Fiber Communication Conference and Exhibition 2017 (OFC 2017) held in Los Angeles on March 23rd, 2017.
OFC 2017 also featured 5 “top scored” papers from DTU Fotonik.
