Optical communication module, and electronic device and docking station comprising same

Abstract

An optical communication module comprises a transparent substrate, a focusing lens, a collimating lens, an optical transmitter, a photoelectric sensor and an optical bandpass filtering film. The transparent substrate comprises a first surface and a second surface which are opposite to each other. The focusing lens is arranged on the first surface, the collimating lens is arranged on the second surface, and the optical aperture of the focusing lens is larger than the optical aperture of the collimating lens. The optical transmitter and the photoelectric sensor are arranged on one side of the second surface, the optical transmitter is aligned with the collimating lens, and the photoelectric sensor is aligned with the focusing lens. The optical bandpass filtering film covers the transparent substrate, is arranged on a light path of the optical transmitter and the photoelectric sensor, and allows light of specific wavelengths to pass through and prevents other light from passing. The invention further discloses an electronic device and a docking station respectively comprising the optical communication module.

Description

technical field [0001] The invention relates to optical communication technology, in particular to an optical communication technology applicable to electronic devices and docking stations thereof. Background technique [0002] Due to its high transmission rate, optical communication technology has been applied more and more widely. However, during the transmission of optical communication signals, it is required to isolate external stray light to avoid interference, which limits its application range. The signal transmission between electronic devices, such as mobile communication devices and their docking stations, is unable to apply optical communication technology due to the inability to isolate stray light, and still relies on electrical connectors for communication. However, the communication transmission rate of the electrical connector is limited, and the exposed electrodes of the electrical connector are also prone to further reduce the transmission rate due to oxi...
