The amount of data processed in data centers is increasing dramatically, and there is rising demand for higher speeds and higher capacities. Data transmission speeds have already entered the era of 400 Gbps and new data centers are being constructed. At the same time, networks between data centers are switching to 400GBASE-ZR (400ZR) compatible equipment and are installing new equipment to reduce operating costs and expand communications capacity.
This white paper describes market trends surrounding 400ZR, the main technical specifications, and test solutions required for deployment and quality maintenance.
