Why not use standard phone cable, as it is only low voltage. This

Standard phone cable, ad in the "normal" white stuff used when wiring
extensions in the house?
If this is what you mean, I am not sure it would be wise to bury this!
If you mean stuff made for burying, where do I get it from (I don't know any
BT engineers!)

Buery it in a bit of plastic 15mm water pipe and eakl teh ends with
expaniding foam.

Probably cheaper than buying armored underground cable, if its all for
very low power...
