An alignment assembly of a first connector part for aligning a first fiber ferrule of the first connector part with a second fiber ferrule of a second connector part during mating of the first connector part with the second connector part. The alignment assembly includes a ferrule carrier to which the first fiber ferrule is mounted. The ferrule carrier is mounted to the first connector part by a support structure. The support structure is configured to allow a movement of the ferrule carrier relative to the first connector part in at least a lateral direction that is substantially perpendicular to an engagement direction of the first fiber ferrule with the second fiber ferrule. A first guiding structure is mounted to or forms part of the ferrule carrier. The first guiding structure is configured to mechanically interact with a complementary second guiding structure that is provided in the second connector part.
