successfully received on the receiver side.
EYE aperture is not enough.
Serial digital signal waveform when the transmission
distance extends or when the cable quality has a problem.
Because the reception level decreases, the EYE aperture
becomes smaller, and the waveform rise/fall time increases,
there is a possibility of failing the normal reception.
However, the conditions are corrected by the cable equalizer
at the reception device side, and thus the signals often can
be received normally.
Serial digital signal waveform when the transmission
distance is expanded, or there is a significant problem in the
quality of the cable.
In this case, the EYE aperture cannot be identified and it is
almost impossible to receive it as a serial digital signal.
