The history of optical fiber
1880-Alexandra Graham Bell invented light beam call transmission.
1960- the invention of electricity and optical fiber
1966- Gao Kun, a scientist in China and the "father of optical fiber", predicted that optical fiber would be used for communication.
1970- an optical fiber with a transmission loss of only 20dm/km has been successfully developed by Corning Company.
1977- First practical installation of telephone optical fiber network
1978-FORT installed optical fiber power for the first time in France.
1979—— Zhao Zisen drew the first practical optical fiber independently developed in China, and was known as "the father of optical fiber in China".
1990- optical fiber for LAN and other short-distance transmission applications
2000-FTTH = > FTTH to Desktop
In 2005, FTTH (Fiber to the Home) fiber directly to the home.
