Thanks for comments Scott.
According to your test results, our 32 fixtures chain is already fragile more due to 32 sockets connection rather than unit loads.

Limiting each segment to about 32 devices is still a good rule of thumb for the reasons that Scott mentioned. But you can go higher under certain conditions (good cable, excellent connectors, etc.).

Exactly, I beleive even a blind repeater (without signal regeneration) would be useful to renew signal and reduce signal reflection which Scott mentioned.

You are right, I got it now!
