Because the chip can handle only 3. With things becoming more reliant on battery power, or power efficiency in general, lowering the voltage is a good way to save on power. 3V Controller Area Network (CAN) transceivers offer advantages and flexibility with respect to 5V CAN transceivers while being compatible and interoperable with each other. Power consumption is lower with 3. There is potential for power supply. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication. Every fiber optic transceiver is defined by a detailed set of specifications.
