Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular relates to an LED light transmitter. Background technique [0002] The so-called optical fiber communication is a method of using light waves to carry information and realize communication. Due to its large capacity and long transmission distance, it is more and more favored by the majority of users. In the optical fiber communication system, the role of the optical transmitter is to convert the electrical signal into an optical signal and send it into the optical fiber line for transmission. The optical transmitter occupies an important position in optical fiber communication. The light source with good performance, long life and convenient use is the key to ensure the reliable operation of optical fiber communication. The optical transmitter of the laser diode light source has high cost and short life, and is suitable for long-distance transmission. LED ...
