如前所述，有了合适的设备和相应的专门知识，任何无线传输都有可能受到干扰。
As said before, with the right equipment and the right know-how, it's possible to jam any wireless transmission.
在20世纪60年代，IBM科学家对于有时会干扰他们的传输、引发错误的电子“噪声”非常头痛。
In the 1960s, IBM scientists were baffled by the electronic "noise" that sometimes interfered with their transmissions, causing errors.
它们通过光纤飞速传输，几乎不丢失数据也不被其他东西干扰（这就是为什么不同的信号可以在同一根光纤中传输以倍乘它的容量）。
They whizz through optical fibres, rarely getting lost or interfering with one another (which is why different coloured signals can be sent down a single fibre, to multiply its capacity).
