An FTTH Wireless Router is an integrated customer premises equipment (CPE) that combines a fiber optic terminal (often with an built-in ONU/ONT) with a wireless access point and Ethernet switch. Its core function is to terminate the fiber connection from a Passive Optical Network (PON), convert the optical signals into electrical data, and distribute internet access via Wi-Fi and wired ports. Key advantages include a simplified, all-in-one design that reduces clutter and installation complexity, support for high-speed triple-play services (data, voice, video), and advanced Wi-Fi features like dual-band support and mesh networking. It is the primary residential gateway deployed in Fiber-to-the-Home (FTTH) networks to provide subscribers with whole-home internet connectivity.
