SEOUL -- South Korea's state research institute has developed the world's top-class ultra-fast optical transmission and reception engine that can provide stable and multi-channel data transfer speed for hyperscale data centers where the demand for fast data speed has increased due to high-definition video content and services using artificial intelligence and cloud computing.

The hyperscale data center refers to a facility for cloud computing and big data storage that has at least 500 storage cabinets covering 929 square meters (10,000 square feet) with more than 5,000 servers connected with an ultra-high-speed optical fiber network.

The Electronics and Telecommunications Research Institute (ETRI) said in a statement on Wednesday that it has developed the world's top-class 400 gigabits per second-class optical transmission and reception engine capable of providing real-time high definition video streaming for some 100,000 viewers simultaneously.

The optical engine was designed especially for data centers that house thousands of servers. Conventional optical transmission and reception modules are 100 gigabit per second-class that splits data speed into four channels of 25 gigabits per second.

ETRI said its researchers have succeeded in developing photophilic elements that can provide 100 gigabits per second per channel. The new engine is small so that multiple devices can be installed onto a single communication device. The global market for hyperscale data centers is expected to grow at an annual average growth rate of 24.25 percent due to high demands from entertainment, research and data storage sectors.
