Smart ATB, designed and developed by Huawei, is an indoor high-speed fiber-access device. The innovation is that the fiber adapters and fiber as well as the internal components are hidden inside the box. Pre-connectorized cables are already connected to the ATB and integrated in its outer shell. In this way, a full and rapid implementation of the ATB and an improvement in technical efficiency can be achieved, and the wall integrity can be ensured. To use the high-speed network access, the user simply has to touch the bottom of the box to make the fiber adapter visible.
