摘要：

Since 1975 the transmission capacity of optical-fiber communications systems has increased 10 times every four years. The most recent development is an amplifier made by doping a glass fiber with erbium. It boosts capacity 100-fold by replacing electro-optical 'repeaters' that regenerate weakened signals.
