Hello Minh Le,
The Cambium Networks Copper Cable is fantastic; please note it is only 1000BASE-T which might be an issue for the bandwidth capable on the 850 range of products.
Ideally, on a highspeed point-to-point link, you’ll use DC and Fibre - I do understand that fiber could be too difficult, but if you do, several companies like AFL sell a hybrid fiber option.
If you do use hybrid fiber, you’ll need an adapter for the 850S. It’s called a Two-Wire to PoE Port Power Adaptor.
This is because the 850S does not have a DC Input available out of the box.
Though if you cannot use fiber, please look at a rugged CAT6 alternative with an LPU rated for the PoE voltage and speed - either 2.5Gbps or 10gbps.
But if your requirement is only 1000BASE-T or 1 Gigabit; please do use the WB3175A Cable and C000065L007B LPU.
Hope this helps, please reply with any other questions you may have.
