It is not imperative to use on of our approved cables, but they are the only ones we can guarantee to work as the specification of the cables is fixed and will not change.
In theory any good “touring grade” quality CAT5e/6/7 cable should suffice but ideally you want to try before you buy, or buy from somewhere with a good returns policy, so you can ensure that it works as expected.
I should add that although @gcumbee has had success with >100m cable runs, it is not something we support so you would be going above 100m at your own risk.
