Hello Ben, this is possible but only with the Non-MIMO SKU's of the PTP820C (and PTP820C-HP). The description will state 'Non-MIMO'. If you have an older PTP820C, two fiber inputs isn't going to be possible. This isn't a comprehensive list of part numbers, but will give you an idea of standard configurations and the non-MIMO description. If you design a PTP820C link in LINKPlanner, it will now default to non-MIMO SKUs.
If you are using two data inputs (Ethernet or Fiber), then you are typically wanting more than 1Gbps across the link. That setup requires LAG. This post should help: http://community.cambiumnetworks.com/t5/PTP-Configuration-Examples/Configuring-LAG-and-In-Band-Management-on-a-PTP820C/m-p/77659#M56
