Global Fujitsu Distinguished Engineer

Takeshi Hoshida


The capacity of photonic networks has increased by several hundred-fold in the last 20 years. In this field, I have had the opportunity to be involved in the development and commercialization of a variety of new technologies, including designing optical methods for multiplexing systems, distributed amplification technology, modulation/demodulation technology, and digital signal processing technology. In the future, I would like to uncover as-yet undiscovered technologies by deepening my knowledge through capitalizing on my curiosity alongside my colleagues to realize networks that are both even larger and greener.
