[RE-wrenches] Underground Data Transmission

[Corey Shalanski]

Our company typically uses Belden 3106A cable (22AWG) for data transmission
on our larger PV sites, which often involves underground runs. We were
recently informed by the manufacturer that this particular cable is not
rated for underground use - whether in conduit or direct burial - and that
furthermore they only offer a 24AWG underground rated cable ($$) or would
have to custom manufacturer a 22AWG version ($$$)

We are wondering what product/method other groups are using for underground
data transmission?
