How to prevent crosstalk between a twisted pair in a SCSI cable?
Yes, there is method to minimize crosstalk. Use very low speed and 1 turn pass-through transformer for every pair. Small ferrite bead with 2 wires = 4 ends. This will decouple each individual pair. On the picture below the ring is horizontal, wires enter ring from top and bottom.
