We consider distributed Josephson junction in the situation when the classical (local) description fails. This takes place, for example, if the critical current is large enough and Josephson screening depth is small. First, we found that the switching to nonlocal model reduce the movability of kinks. Second, it was shown that kink-kink interactions may result in emerging of new breather-like objects. The properties of these pulsating objects have been studied.
