Max channel bandwidth is 56mhz, but you should easily be able to get 250Mbps out of a 40mhz channel... I'm not sure there's much point in going in narrower than that. Actually, doing SISO at a 56mhz channel might make more sense, that should get around 275mbps at 256qam (and a bit more if the link will do 1024qam, obviously), but then you'd only need a one polarity, so it may save a bit on coordination, and you wouldn't need to buy the extra duplexers.
