“…This was a service with a known revenue structure as opposed to the unknown revenues from future broadband services. This approach became known as a 'telephony entry strategy' and led to the invention and development of the 'TPON' (Telephony over Passive Optical Network) system [4,5]. Several manufacturers became heavily involved in the development including Fujitsu, Alcatel, and Nortel.…”

“…The bunch fiber is drawn from bunched multiple preforms and each preform includes one respective core. However, the passive optical network (PON) [6] was utilized to provide cost-and space-efficient networks for the subscriber lines, and the MCF became unnecessary anymore for the density improvement and has not been commercialized for SDM transmission then. In the late 2000s, the SDM technologies had rapidly come to attract attentions again [7], since the future capacity crunch became an issue with reality [1,2].…”

Abstract:We experience Internet traffic growth of 100 times every 10 years. However, the capacity of existing standard single-mode fiber is approaching its fundamental limit regardless of significant realization of transmission technologies which allow for high spectral efficiencies. Space division multiplexing (SDM) based on multicore fibers (MCFs) has emerged as a solution to the problem of saturation of the capacity of optical transmission systems. This article presents the recent progress on the MCFs for future large capacity long-distance transmission systems. In MCFs, there is a tradeoff relationship between low crosstalk and high multiplicity, therefore the maximum number of cores and the core arrangement have to be carefully determined based on the required crosstalk level and core size. The state-of-the-art of fabricated MCFs and the transmission experiments using MCFs are reviewed. The current maximum capacity-distance product in MCF transmission is 368.2 (184.1+184.1) Pb/s/fiber km with the relative spatial efficiency of 4.7 compared with a standard single-mode fiber. In order to increase the spatial efficiency as well as the capacity-distance product further in MCFs, the possibility of heterogeneous MCFs and few-mode MCFs is also presented.

“…DS includes the passive double star (PDS) with star coupler [1], and the active double star (ADS) with remote terminals (RT) [2]. In the PDS configuration, the fiber from the station to the branch point, as well as the indoor transmission equipment, can be shared by the multiplex equipment of the multiple-user side.…”
