When they presented the Airfiber 5X did they say 200km range with a straight face? Capture

I think they said that because the ptp650 said exactly that as well.

Normally at that distance using TDD, the xmt/rcv guard time will cut significantly into capacity. It’s like road construction where they turn a mile of 2 way road into a single lane with flaggers at each end. Every time they switch the flow, there is a mile of empty road.

Re: [AFMUG] Sent from Snipping Tool
Once upon a time, in a land far far away, there was a batwing logo company that was working on the idea of storing the data in the air. That is still a good ideal for longer paths. On a 50 mile path, packets could be about 250 microseconds. That should support a 2.5 Gbps link if I haven’t fouled up the math. The longer the path length, the higher the data rate could be if you can modulate it.
