No, we can't. The longest 40G Passive DAC cables are 7m. Because the Passive DAC does not contain electronics for signal conditioning, it will affect the data transmission if the cable length is longer than 7m. For the long distance passive cables, you can choose the 40G AOC series."

No, the compatibility of both ends of this product is consistent. I recommend that you buy a FS BOX and change the encoding on one end to Arista, or directly choose a dual-compatible custom product #49575 .

No, it can’t be used in the stack port of your device. FS DAC & AOC can only be used in the business port of the switch to achieve virtual stacking, but can not be used in the stack port to achieve physical stacking. The stacking through the stack port of device belongs to physical stacking which needs a specific stacking cable, and it is under development for now.

The use of the wire has nothing to do with the thickness of gauge, there is no problem when using it, as long as the product is compatible and the power of switch is not overloaded.
