Delay distortion is a guided transmission media phenomenon where network data signals are transmitted via a medium at a certain frequency and speed.
Delay distortion occurs when signal velocity and frequency vary. This means that all signals do not arrive at the same time, resulting in distortion of the signal. This term is commonly used in fiber optics.
Distortion refers to the change or alteration of an object. Data signals must be transmitted over a medium with a defined frequency and speed. Digital data are highly vulnerable to delay distortion. This is because any transmitted data packet bit can spill and destabilize the overall packet transmission pattern.
Delay distortion may be resolved with different techniques. The best example is a telephone line, which equalizes speed signals with medium frequency.
