PTP in between ISP modem and router?

If I have my ISP’s modem located 100’ feet away from where I’d like my router, and it’s not feasible to get cable to it, what are the ramifications of putting 2 PTP devices in between? So it would be ISP Modem—Mikrotik SXT >< Mikrotik SXT—Router.

Is that the most appropriate way to do that?
