I am working for a cable manufacturing compnay as a sales engineer. My job is to introduce communication products such as cable modem to CATV operaters and support them. My largest interest is FTTH(Fiber to the home) .
Thanks to my current business, I have opportunities to visit foreign countries, US, Korea, Taiwan, China, etc.
Once I worked in a field of Superconductivity. I started the study with Niobium Nitride film.
When 'High Temperature Superconductivity' was discovered in 1987, an explosive boom called 'Superconductivity Fever' took place. That was one side of, so called, "Bubble Economics".
