光纤通讯网络中以光学形式接通数据的光开关不久后可使光纤实现闪电般速度的长距离巨量数据传递的潜力。曾经发展混合开关的澳大利亚墨尔本大学光子学研究室主任R.Tucker说,“一根光纤可能在1秒时间内传输相当于一个中等规模城市图书馆藏书的信息量。但由于光信息必须转换成电信号,并在沿途许多地方需作电处理,这种潜力仍未得到充分开发。”Tucker研究组宣称,他们所研制的开关是第一个允许数据包完全以光学形式通过开关通讯网络的开关。1990年11月,该组演示了一种能以700Mb/s速率处理数据的开关样机,其速率为目前光纤网络开关的实际上限。
Optical switches in the optical communications network that turn on data optically soon have the potential to enable long-haul bulk data transfer at lightning-fast speeds. R. Tucker, director of the Photonics Laboratory at the University of Melbourne, Australia, who developed hybrid switches, said: “An optical fiber can transmit the equivalent of a library of medium-sized cities in less than a second, but because optical information must be converted Electrical signals, and the need for electrical processing in many places along the way, this potential has not been fully exploited. ”Tucker’s team claimed that the switches they developed were the first to allow packets to pass through the switching network optically switch. In November 1990, the team demonstrated a switch prototype that can process data at 700Mb / s at the current maximum limit of fiber optic network switches.
