For AM26C31 differential signal output, do I need to connect a capacitor between the differential signals?

It is best to add it in front of the differential signal receiving end, which can effectively filter differential mode interference, because it is difficult to ensure that your differential line is not perforated and equidistant, and these will introduce some differential mode interference.

How to select the value of the capacitor?

The value of the capacitor is hard to say. It depends on the effective signal frequency you want to transmit and the differential mode interference frequency you want to filter. Generally, it is more pF. In principle, the effective signal impedance is much greater than the matching resistance.
