The invention relates to an optical module 10) comprising a guiding element (30) adapted to guide optical radiation (P); a converting element (50, 200) adapted to convert received electrical energy into optical radiation or to convert received optical radiation into electrical energy; a mirror (70) arranged in the beam path (40) between the optical guiding element and the converting element and configured to optically connect the guiding element and the converting element; and a carrier (20) having a first surface section (22) for carrying the mirror and a second surface (23) section for carrying the converting element. The carrier is made of polymer material.
