Yes, so then multiply by two for dual polarity if it can be licensed for a figure of 500 Mbps FDX per 40 MHz H & V PTP link.
If 80 MHz, multiply by two again, resulting in a figure of 1 Gbps FDX. Which my back of the napkin calculation says is actually a conservative, pessimistic estimation for the FDX data rate you should see in a 1024QAM, 80 MHz dual polarity link. An Exalt ExtremeAir 18GHz radio that is 80 MHz wide, dual polarities, 256QAM 5/6 code rate is exactly 1 Gbps FDX and can be treated like a 1000BaseLX fiber patch cable between two routers.
