Summary: | The invention discloses a non-contact multi-channel high-speed data transmission detachable connector. Light emission is realized by adopting a silicon optical module/integrated multi-path vertical cavity surface laser (VCSEL) and a large-angle beam expanding optical element. A large-view-field receiving optical system and a micro-optical device are used for shaping light beams, and a multi-element photoelectric detector chip is used for receiving light. Direct modulation or phase modulation is adopted to realize optical communication, and the single-channel communication rate can reach Gbps. The influence of stray light on the communication quality is reduced by means of spectrum and electrical isolation, and crosstalk between channels is prevented. And the data capacity is improved by utilizing a wavelength division multiplexing technology. The working temperature range of the light source chip and the photoelectric detector chip is large, and the whole connector is subjected to airtight packaging and can w |
