  Nine Things to Remember About the Future of Copper in Computing

  By Michael Kanellos, Head of Influencer Relations, ³Ô¹ÏºÚÁÏ and Vienna Alexander, Marketing Content Intern, ³Ô¹ÏºÚÁÏ

  Is copper dead?

  Not by a long shot. Copper technology, however, will undergo a dramatic transformation over the next several years. Here¡¯s a guide.

  1. Copper is the Goldilocks Metal

  Copper has been a staple ingredient for interconnects since the days of Colossus and ENIAC. It is a superior conductor, costs far less than gold or silver and offers relatively low resistance. Copper also replaced aluminum for because its 40% lower resistance improved performance by 15%¹.

  Copper is also simple, reliable and hearty. Interconnects are essentially wires. By contrast, optical interconnects require a host of components such as optical DSPs, transimpedance amplifiers and lasers.

  ¡°°Õ³ó±ð in optical technology is ¡®Whatever you can do in copper, do in copper,¡¯¡± says Dr. Loi Nguyen, EVP of optical technology at ³Ô¹ÏºÚÁÏ.

  2. But It¡¯s Still a Metal

  Nonetheless, electrical resistance exists. As bandwidth and network speeds increase, so do heat and power consumption. Additionally, increasing bandwidth reduces the reach, so doubling the data rate reduces distance by roughly 30¨C50% ?(see below).

  As a result, optical technologies have replaced copper in interconnects five meters or longer in data centers and telecommunication networks.?
