Power consumption of optical transmitters
An optical transceiver is a complex device that performs both electrical-to-optical (E/O) and optical-to-electrical (O/E) conversion. Its power is primarily consumed by its laser driver, post-amplifier, and the DSP that handles signal integrity. Lower power consumption means less heat output, reducing the burden on expensive cooling systems and creating a more stable operating environment. Environmental Responsibility: The IT industry is under pressure to minimize its carbon footprint. Implementing energy-efficient data center practices is. efficiency and consumes watt-class high power and occupies a several-square-millimeter footprint, which limits large-scale integration for par llel trans...
