As described in Chap. 7 , the transmission capacity of optical fiber transmission systems has dramatically increased with the introduction of WDM technology. However, even with the adoption of digital coherent reception technology explained in Chap. 8 , it has become evident that this capacity increase is approaching its limit. To overcome this limitation, the introduction of new innovative technologies is essential. Space division multiplexing (SDM) technology using multi-core fibers (MCF) or multi-mode fibers (MMF) is a promising candidate to overcome this limitation. This chapter provides an overview of SDM technology and introduce large-capacity transmission experiments utilizing this approach.

摘要

As described in Chap. 7 , the transmission capacity of optical fiber transmission systems has dramatically increased with the introduction of WDM technology. However, even with the adoption of digital coherent reception technology explained in Chap. 8 , it has become evident that this capacity increase is approaching its limit. To overcome this limitation, the introduction of new innovative technologies is essential. Space division multiplexing (SDM) technology using multi-core fibers (MCF) or multi-mode fibers (MMF) is a promising candidate to overcome this limitation. This chapter provides an overview of SDM technology and introduce large-capacity transmission experiments utilizing this approach.
