airFiber - AF24 and AF24-HD compatibility

AF24 and AF24-HD can create a link together. However maximum throughput will be limited by the AF24 (up to 6X, 64QAM).

If you want to upgrade an existing AF24 link, you can replace first one side and keep the link up (after you plug in the Ethernet cable into the new unit). And then, replace the other AF24 unit, reducing downtime to just a few minutes.
