CameraLink cables contain wire pairs, which are twisted in such a way that the
cable impedance matches with the LVDS driver and receiver impedance. Excess
stress on the cable results in transmission errors which causes distorted images.
Therefore, please do not stretch and bend a CameraLink cable.
In robots applications, the stress that is applied to the CameraLink cable is especially high due
to the fast movement of the robot arm. For such applications, special drag chain capable cables
are available.
