Data Centres Turn to Light Instead of Copper Wires

Vocabulary

Article

Data centres process vast amounts of information every day, using hundreds of tonnes of copper wire to deliver electrical power and transmit data. However, industry leaders believe copper's role is ending not because supplies are running out, but because a better technology exists. These facilities face a challenge: the copper wires connecting computer servers create heat and slow down data transmission. Engineers are now replacing these wires with fibre optic systems that use light instead of electrons.
