1. An insulation device arranged to be fixed on an electrical board of an optical wireless communication equipment, the electrical board comprising a receiving surface on which is mounted at least one optical assembly comprising an optical concentrator coupled to a photodetector, the insulation device comprising an enclosure having a height at least equal to a height of the optical assembly, the enclosure comprising in its thickness an opaque material, the insulation device comprising at least one holder located inside the enclosure and having a shape complementary to a shape of the optical concentrator,
the insulation device being arranged such that, when the insulation device and the optical assembly are mounted on the electrical board, the enclosure surrounds the receiving surface so as to insulate the optical assembly from unwanted optical signals, and the optical concentrator is positioned in the holder such that the holder assists in holding the optical concentrator in position in the optical wireless communication equipment.
