Idea

A triangulated functor F:TTF : T \to T' between two triangulated categories TT and TT' is an additive functor that commutes with translation and preserves the distinguished triangles.

(Neeman 01, def. 2.1.1)

Triangulated functors are also called exact functors (not to be confused with the other meaning of exact functor).
