These advanced semiconductors also allow greater power integration, which improves the efficiency and reduces the cost of electricalconverters.
这些先进的半导体还允许更大的动力合并，这提高了效率，降低了电转换器的成本。

Intel did not have to invent anything new, but it did have to work out how to make small, cheap versions of the converters that turn electrical signals into light and vice versa.
英特尔不需要发明任何新东西，它只要想办法使电子信号和光信号之间的相互转换更小巧便宜。

Electrical Circuitry: Converters stabilize the current's varying frequencies. Transformers boost voltage from 690 volts to more than 22,000, so current travels efficiently over long-distance lines.
