Crosstalk in fiber optic network | What is Crosstalk
This page explains crosstalk concept in fiber optic network. It explains far end crosstalk with respect to fiber.
The undesired coupling from one channel to the other is referred as crosstalk. The same has been shown in the figure-1.
Far End Crosstalk:
It is ratio of optical power from output port-1 and output port-2.
The wavelength of the two ports are equal in value.
Here port-2 is isolated from port-1 normally. It is expressed in dB.
For WDM case, signals in two output ports will have different wavelengths. Hence here isolation term is used in place of far end crosstalk.
