Editor's Notes
- Let’s go back 20 years and recap what happend back then
- What I did not know – these were interesting times in telecom: NYT: The working paper No. 179, 1994, of the Center for Coordination Science at Massachusetts Institute of Technology describes the concept as follows: "The information superhighway directly connects millions of people, each both a consumer of information and a potential provider. (...) Most predictions about commercial opportunities on the information superhighway focus on the provision of information products, such as video on demand, and on new sales outlets for physical products, as with home shopping. (...) The information superhighway brings together millions of individuals who could exchange information with one another. Any conception of a traditional market for making beneficial exchanges, such as an agricultural market or trading pit,
- If so – could there have been any better time to start an optical networking company? Could there have been any nicer place than this beautiful building?
- It took a year to get the first product to market – solving a specific customer problem:
