N1 - Funding Information:
EXAT Initiative has also led to the creation of a series of pioneering national projects on SDM technologies, such as i-FREE (Innovative Optical Fiber Technologies: 2010–2012), i-ACTION (Innovative Optical Communication Infrastructure: 2011–2015), and i-FREE2 (Innovative Optical Fiber and Communication Technology for Exa-bit Era with SDM: 2013–2018) which will be described in detail in Chapter 8. Recently, new projects SDM-PN (R&D of Space-Division Multiplexing Photonic Node: 2016–2020), i-FAST (R&D on Innovative Optical Fiber and Communication Technologies Toward Standardization: 2018–2022) and OCEANS (R&D on high-capacity multi-core fiber transmission systems: 2018–2022) were initiated and are ongoing. Furthermore, an EU-Japan coordinated R&D project SAFARI (Scalable And Flexible optical Architecture for Reconfigurable Infrastructure: 2013–2017) was created as the first internationally collaborative project between Japanese EXAT and the European partners, commissioned by the Ministry of Internal Affairs and Communications (MIC) of Japan and European Commission Horizon 2020. These national projects have been leading the SDM technologies in the world, creating many world records such as 1-Pbit/s transmission (2012 [25], 2017 [26]), 1-Ebit/s·km transmission (2013) [27, 28], 2-Pbit/s (2015) [29, 30] and 10-Pbit/s transmission (2017) [31].

N2 - In this introductory chapter, the physical limits and prospects of the present optical fiber communication systems as well as EXAT initiative and 3M technologies are briefly described. Then, the demands from future applications, namely ultra-realistic communications, and wireless communication networks, such as 5G technologies are described. Lastly, the state-of-the-art terrestrial optical transmission systems and optical submarine cable systems are summarized.
