The 40G DAC is composed of a fixed-length copper cable and 40G transceiver s at both ends. The transceiver and the copper cable cannot be separated. Different from 40G optical transceiver s, the transceiver s at both ends of 40G DAC do not have optical lasers and electronic components, and transmit electrical signals through copper cables without the function of photoelectric conversion.
