Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long (17,398 mi; 15,119 nmi) fibre optic mostly-submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. [1]
The list includes figures for both fixed wired broadband subscriptions and mobile cellular subscriptions: [6] Fixed-broadband access refers to high-speed fixed (wired) access to the public Internet at downstream speeds equal to, or greater than, 256 kbit/s.
First developed in the 1970s, fiber-optics have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. [7] Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in backbone networks in the developed world.
A few years later they produced a fiber with only 4 dB/km, using germanium oxide as the core dopant. Such low attenuations made fiber optics practical for telecommunications and networking. Corning became the world's leading manufacturer of optical fiber. In 1977, considerable attention was given to Corning's Z Glass project.
Sumitomo Electric also continues to be the leading manufacturer of composite semiconductors (GaAs, GaN, InP), which are widely used in semiconductor lasers, LEDs, and mobile telecommunications devices. The company is one of the top three manufacturers in the world of optical fiber. Sumitomo Electric Industries is a part of the Sumitomo keiretsu.
