I have done some searching around but have not found anything definitive, and/or my background is weak in this area and I may be understanding poorly.
I will have 2-4 PoE cables that will be run underground a distance of up to 300ft. There will be no sources of interference near the cables. There will most likely be 4 cables, with the possibility of others in the future.
My guess was that I would want a 2" conduit to run these through. I have seen it suggested that PVC be used for this, which I assume refers to some flexible PVC conduit, which I have not found in 2" x 300ft variety, if I remember correctly, or it is too expensive.
I have also seen Carlon's Carflex Liquidtight conduit (https://carlonsales.com/carflexliquidtightnmconduitparts.php), but these appear to be expensive for my basic needs and the 2" conduit Edit Meant to say that the 2" conduit only goes up to 100'
Currently, it appears that the cheapest solution would be to run each cable in its own 3/4"-1" PEX tubing, but I would rather leave room for further cable(s) in the future, and a separate conduit for each cable is awkward. I understand that direct burial with appropriately shielded cable is also an option but I would rather allow, again, for addition of cables, but also cable replacement, without unearthing the trench.
I wonder if anyone has any recommendations for materials or specific products.
edit devices are going to be PoE cameras
