The full range of XPON solutions have been upgraded to help operators achieve full coverage of "gigabit broadband"

Recently, a team dedicated to the research and development of passive optical network technology announced that its full range of XPON solutions have completed a major upgrade. By integrating the advantages of EPON and GPON technologies, it has launched multi-mode compatible devices that support 10G EPON, XG-PON, and XGS-PON. It can meet the broadband upgrade demands of operators from "100 megabits to 1 gigabit", and has been applied in the construction of "gigabit cities" in many provinces in China, especially demonstrating significant advantages in the home broadband access scenario. ​

Advantages of home broadband access application: In the home scenario, this XPON solution addresses the pain points of traditional broadband such as "insufficient bandwidth, multiple devices lagging, and complex maintenance". On the one hand, the 10G EPON module supports single-user downlink gigabit and uplink 100M speeds, and can easily carry high-bandwidth applications such as 4K/8K ultra-high-definition videos, cloud gaming, and VR home entertainment. For instance, downloading an 8K movie (about 100GB) only takes 20 minutes, which is 10 times faster than traditional 100M broadband. On the other hand, the home gateway type ONU in the solution integrates Wi-Fi 6 technology, supporting concurrent operation of dual frequency bands of 2.4GHz and 5GHz, with a maximum connection capacity of 128 devices. Even if 20 devices such as smart TVS, vacuum cleaners, mobile phones, and tablets are turned on simultaneously in the home, It can still maintain low network latency (≤20ms), avoiding problems such as video conference lag and game disconnection. In addition, passive optical networks use optical fibers for transmission, which have strong anti-interference capabilities and can avoid rate fluctuations caused by neighboring broadband sharing. Moreover, the service life of optical fibers is up to 30 years, reducing the trouble of frequent line replacement for home users. The maintenance cost is 60% lower than that of traditional copper cable broadband. ​

The core of this upgrade lies in the two-way optimization of "full-scenario adapted hardware" and "intelligent operation and maintenance system". In terms of hardware, the newly launched XPON optical line terminal (OLT) adopts a high-density port design. A single device can support the access of 128 optical network units (ONUs), with a port density 50% higher than that of the previous generation. At the same time, it supports hot-swswable modules, allowing operators to complete equipment expansion without downtime. Optical network units (ONUs) are further classified into three major categories: "Home gateway type", "Enterprise Access type", and "Outdoor Waterproof type". Outdoor waterproof ONUs have passed the IP67 protection certification and can be directly deployed in community corridors and street cabinets, adapting to complex outdoor environments.
