Abstract

The invention discloses a parallel light emitting circuit, and belongs to the field of photoelectric digital transceiving modules. The parallel light emitting circuit comprises a microprocessor, a driver and a laser array; the microprocessor is used for sending a control instruction, receiving feedback and alarm signals of the driver and setting compensation for the driver; the driver is used fordetecting and processing the electric signal and driving the laser array; the driver is used for realizing multi-channel parallel data transmission, the driver is provided with 12 independent channels, the data transmission rate of a single channel is 10Gb / s, and each channel can work independently; and the laser array is used for emitting laser. According to the parallel light emitting circuit, the function of converting electric signals into light signals can be achieved, and high-speed data transmission with the maximum capacity of 12x10 Gb / s can be achieved by adopting a circuit structurehighly integrating the multi-path driver, the laser array and the microprocessor. The parallel light emitting circuit has the characteristics of high data rate and high line integration degree.

Description

technical field [0001] The invention belongs to the field of photoelectric digital transceiver modules, in particular to a parallel light emitting circuit. Background technique [0002] As communication technology is challenged by ever-increasing bandwidth and speed requirements, large-capacity, high-speed optical communication has become an inevitable trend in the development of the information age. Optical communication technology is a communication technology that uses light waves as the carrier and free space or waveguide as the transmission medium. Since its inception, it has been widely used in national defense, telecommunications, etc. In various military and civilian communication fields, it has become the cornerstone of modern information technology. [0003] As the core components of optical communication, the technical development of optical transceiver modules is also becoming more mature, and is gradually developing in the direction of high speed, intelligence ...
