Note that at higher frequencies, the physical length of a cable is different from its electricallength.
请注意,在高频下,电缆的物理长度与其电气长度不同。

Two arms of the interferometer are different in length by one -quarter of a guide wavelength, allowing the device to operate at its optimal linearity point without external electrical bias.
干涉仪的两个臂长相差波导波长的四分之一,使器件在最佳线性点工作,无需外加电偏压。

Side cutters are useful for cutting electrical flex to length.
