atek electrical components include single heterojunction, double heterojunction, and quantum well laser diodes. Quantum well laser diodes have the advantages of low threshold current and high output power, making them mainstream products in market applications. Compared with lasers, laser diodes have the advantages of high efficiency, small size, and long service life, but their low output power, poor linearity, and less than ideal monochromaticity greatly limit their application in cable television systems, preventing the transmission of multi-channel, high-performance analog signals. In the return module of a bidirectional optical receiver, upstream transmission generally uses quantum well laser diodes.
