TTL vs OPTO vs LVDS

Hello,

I use a Framegraber that cann recive the hardware trigger by 3 ways

- TTL trigger.
- OPTO-Isolated trigger.
- LVDS trigger.

Now i have conected OPTO-Isolated, but i have interferences and
sometimes a electric interferente apears and a capture is taken.

Which mode is the better to avoid interferences?
What's your experience?

Thanks.
Pau
