Z-axis
The Z axis is in the third dimension, perpendicular
to the X and Y axes and indicates depth. See axis.
zero dispersion point
In telecommunications, the wavelength where material
dispersion is minimal. With standard fiber optic cable, that
wavelength is 1310 nanometers.
zero suppression
In telecommunications, techniques that limit the
number of consecutive data 0's that may be transmitted. For DS1
without B8ZS, fifteen data 0's are the maximum allowed.
zero timing point
The point at which all the video signals must be in
synchronization (typically the switcher input).
zero-crossing of subcarrier
The zero voltage point of subcarrier (the point
where the waveform passes through zero volts).
