日本舉全球之先將下一代光纖實際用於電信訊務，首先建立多核光纖的製程與連接技術，再者預期混合型光纖為最終目標，在多模中需要建立諸如解調變處理的相關技術。與現有的單核光纖相比，技術仍有待加強，當務之急是讓整合產官學研全力研究發展。

Japan is the first in the world to use the next generation of optical fiber for telecom services. First, it establishes the process and connection technology of multi-core fiber. Furthermore, hybrid fiber is expected to be the ultimate goal. In multi-mode, it is necessary to establish related technologies such as demodulation processing. . Compared with the existing single-core fiber, the technology still needs to be strengthened. It is imperative to integrate the industry, government, and research study to jointly develop technology needed for future application.
