In the digital economy era, as a large number of new applications emerge, problems such as slow internet speeds and weak signals are becoming increasingly common in everyday network use. Fiber-to-the-Home (FTTH) is now widely deployed for home broadband; however, when users demand higher bandwidth, this approach also has shortcomings such as the limitations of network cables and poor WIFI wall-penetration capability, leaving the actual speeds of terminal devices below the expected rates.

To address these issues, the FTTH upgrade solution FTTR has emerged. Its core concept is to bring optical fiber into every room, with master and slave ONTs connected by a single optical fiber to achieve high-speed coverage throughout the home. Using optical fiber transmission, it is laid once and delivers long-term performance.
