How do you want them to operate ?
Is it as simple as "switch on, fan & lights come on; switch off, fan & lights go off" ? Presumably with a separate switch built into the fan to locally control the fan & light locally ?
If that's the case, then you wire them just the same as you'd wire two pendant lights - switched line to one unit (either neutral direct to unit, or via the switch), and loop off the switched line & neutral off to the second unit. If the fan & light combo has separate connections for the light & fan, then you link these together (both neutrals to the supply neutral, both line connections to the supply line).
