Narrative:

Cleared to land on runway xx. Made approach to runway with student at controls and landed aircraft. Arrestor cable was deployed; we didn't see it before there was no time to execute a go-around or come to a full stop. When I observed the cable I pulled back on the nose to get weight off the nose wheel and main tires rolled over the cable. Aircraft made contact with cable. Upon shutdown and inspection of the aircraft I observed no damage. ATC called and I reinspected the aircraft a second time and observed no damage. It felt like nothing more than running over a lip/seam between pavements and there was no sign of damage. Flew aircraft back to [home base]. I then asked maintenance to look over the aircraft as well. No damage was found by the mechanic.the problem was caused by the cable being deployed; and ATC not knowing and/or informing pilots. ATC stated the cable should not have been deployed. As an additional mitigating step; when the cable is deployed there should be flags or something to that effect that come up to signify to pilots that the cable is deployed. It's invisible until you are very close to it. Had it been more visible then I could have timely executed a go-around to avoid it entirely.
