Alexander Graham Bell, the American inventor of the phone, first endeavored to utilize light around 1880. In any case, lightwave correspondence did not end up being attainable until the mid-twentieth century, until the trend-setting innovation gave a transmission source, the laser, and an effective medium, the optical fiber. The laser was created in 1960 and, after six years, scientists in England found that silica glass strands would carry light waves without attenuation, or loss of signals. In 1970, another sort of laser was created, and the first optical filaments were developed commercially.
