Maximum Cable Length from Controller to First LED in Light String?

Is there a maximum suggested (factory-supplied) data cable length between my ESP32 controller and the first light (12VDC 5050 RGBW 6000K, 0.96W pixel LED) of a string of approx. 50 lights. The reason I ask is because I would like to have the roof peaks on separate feeds from the controller. It might be 30-40 ft to the first light in the string.

Lookup Long Data Lines in the KB.

Differential pairs work very well in this scenario.

According to YPS these are supposed to work for long distances: https://yourpixelstore.com/product/yps-extensions/
