China Unicom Fiber Optic Cable to Home Technology

China Unicom delivers high-speed internet to homes using Fiber to the Home (FTTH) technology with advanced optical fibers and GPON ONTs.

Overview of FTTH Deployment

China Unicom uses fiber optic cables directly to residential homes to provide high-speed internet, IPTV, and telecommunication services. This approach, known as FTTH, ensures faster and more reliable connectivity compared to traditional copper lines. The fiber network typically includes trunk cables, distribution cables, and drop cables that connect the main network to individual homes.

Optical Fiber Technology

China Unicom has adopted advanced optical fibers such as G. 654. E low-loss, large effective area fibers, which are optimized for high-speed, long-distance transmission.

These fibers have been tested in harsh environments, including deserts and snow-covered regions, to ensure durability and performance. The network uses single-mode fibers capable of supporting high-capacity data transmission, including 100G single-wave systems.

Fiber Cables and Installation

For home connections, China Unicom typically uses FTTH drop cables, which can be flat, figure-eight aerial, or round cables depending on the installation environment. These cables are designed for aerial, duct, or direct-buried applications, providing flexibility for urban and rural deployments. Indoor wiring often uses PVC-jacketed cables with OM1–OM4 fibers to meet different bandwidth requirements.

Equipment: ONUs and GPON TechnologyAt the customer premises, China Unicom installs Optical Network Units (ONUs) or GPON ONTs, which convert optical signals into Ethernet or Wi-Fi for home devices. These devices support dual-band Wi-Fi and multiple ports for high-speed connectivity.

The ON

Us are compatible with international standards and undergo rigorous quality control to ensure reliable performance.

Providers and Standards

China Unicom collaborates with leading fiber and equipment manufacturers such as YOFC, FiberHome, and GL Technology to supply optical fibers, cables, and ONUs. The network adheres to ITU-T standards for optical fibers and international quality certifications, ensuring high performance and interoperability.

Summary

China Unicom's fiber-to-the-home service combines advanced optical fibers, robust drop cables, and GPON ONTs to deliver high-speed, reliable internet directly to residences. The network is designed for long-term performance, low signal loss, and adaptability to various installation environments, making it a leading solution for residential broadband in China.
