Introduce two measurement methods of cable delay using two-way compare, it is aneffec-tive solution to deal with the difficulties of cable delay measurement, which caused by the too long ofcable or the complexity of the environment and so on. The main principle of this method is measured twiceto establish the equations by changing the direction of signal transmission in the cable, then calculated theca-ble delay. Practice shows that the approach is proven effective and has higher practicality.
