On the picture below is presented crosstalk measured on 2 channels. On one channel is pulse which is about 55ns wide. Disturbing channel is 10 ns long. Delay is value on generator, but disturbing channel cables were 30 cm longer so its makes about 1ns delay in addition. Plot will be shifted to the right. These are preliminary results. We have to make this measurements with lvds adapter to avoid signal reflections in cable.

COMMENT: It may be interesting to see coincidence of RISING edge of the measured pulse with FALLING edge of the disturbing pulse. Could you therefore extend the "delay" to -10 ns at least (or better to -15 ns) with the same width of the disturbing pulse?.
