The answer is: utilize “ invisible plastic fiber optic cable ” for exposed wiring, currently it is the most mainstream and mature solution available for installations that do not involve conduits. FTTR, or Fiber to the Room, is a cutting-edge technology that revolutionizes fiber optic installations. Unlike traditional fiber optic deployments that rely on centralized distribution points, FTTR brings the fiber connection directly to individual rooms or specific areas within a building. In this article, we'll explore the ins and outs of FTTR Invisible. Based on FTTR network solutions, we understand that there are two primary installation methods: concealed wiring via conduits and exposed wiring. The concealed conduit method is suitable for new home renovations or the remodeling of older homes, provided that existing conduits can be utilized to. FTTR technology utilizes optical fibers to replace traditional network cables, offering characteristics such as low latency, high bandwidth, no attenuation, and strong wall-penetration capabilities. It consists of three components: the Master FTTR Unit (Main FTTR Unit, MFU), Slave FTTR Units (Sub FTTR Units, SFUs), and an indoor optical distribution network (ODN). It also provides terminal interconnection. Huawei's fiber to the room (FTTR) solution extends fibers to rooms and provides various gigabit Wi-Fi 6 master/slave FTTR units, all-optical components, and optical cable construction tools, enabling users to enjoy stable gigabit Wi-Fi experience in every corner of rooms at every moment.
