1. A communication module for a system for transferring data by light beams, comprising:
a transmitter including a light source and adapted to emit a first light beam having encoded data;
a receiver including a light sensor and adapted to receive a second light beam;
wherein the transmitter and the receiver are arranged offset from each other in a first direction;
wherein the transmitter is adapted to emit the first light beam in a second direction orthogonal to the first direction;
wherein the receiver includes a mirror pivotable about a pivot axis, extending in the first direction, between a folded-out position and a folded-in position;
wherein, in the folded-out position, the mirror is adapted to deflect the second light beam, incident from the second direction toward the light sensor; and
wherein, in the folded-out position, the mirror is adapted to deflect the second light beam, incident from the second direction, into a third direction orthogonal to the first and second directions.
