Korea’s state-run Electronics and Telecommunications Research Institute (ETRI) said on Tuesday its researchers have developed a proprietary technology that deliver data through the web at 25Gbps, 10 times faster than the current maximum speed of 2.5Gbps. This enables users to download a 3GB movie just in a second. This is similar to the speed of a human’s feel of touch, which enables data delivery in 0.001 second.
The ETRI branded this technology as TiC-TOC (Time Controlled-Tactile Optical Access), which can be realized by improving equipment on the existing fiber optic line for Internet communication.
Researchers developed a high-speed optical signal receiver module to clearly restore signals even with a low level of optical input power. They also developed a media access control to handle data delivered via the fiber optic cable without delay. The two technology solutions can be used to upgrade an optical network terminal installed at residential or commercial buildings, allowing the use of a 25Gbps-speed web service.
Researchers expect the technology will help boost high-definition one-person media business and the multimodal and interactive entertainment industry. The technology was already transferred to an unnamed local company for commercialization possibly next year.
