DT, it can look like coax to the lay person but have you actually cut it open or skinned it back?
It should have 6 pairs wrapped in a plastic jacket
and may or may not have a waxy substance like silicone under the outer jacket.
Are there any markings on the jacket?
Brand name, cable part number?
If it is coax, don't use it. There are plenty of places locally to get 6 pair direct burial cable.
