Overview and Development Background of FTTH Technology
FTTH (Fiber To The Home) is an optical fiber access technology that directly deploys the Optical Network Unit (ONU) at the user's home or enterprise. It represents the closest form of fiber optic access to the end user within access network technologies, second only to FTTD (Fiber To The Desktop).
Technical Principles
The FTTH network architecture mainly consists of three parts:
1. OLT (Optical Line Terminal): Located at the operator's central office, responsible for channel connection control, management, and maintenance; equipped with distance measurement and bandwidth allocation capabilities.
2. ODN (Optical Distribution Network): Includes POS (Passive Optical Splitters), which distribute downstream optical signals to multiple users, allowing multiple users to share a single fiber.
3. ONU/ONT (Optical Network Unit/Terminal): Installed at the user end, connecting to the end-user devices.
FTTH uses a point-to-multipoint tree topology. The maximum transmission distance between the OLT and ONU can reach 10-20 kilometers. Through time-division multiplexing technology, bandwidth is shared among multiple users. Each OLT can support 32 ONUs (expandable), providing bandwidth up to 1 Gbps.
Technical Advantages
FTTH offers significant advantages compared to traditional access methods:
1. Ultra-high speed and low latency: Provides transmission rates up to several gigabits per second, with latency as low as milliseconds, enabling seamless real-time applications.
2. Passive network architecture: Majority of devices from the central office to the user are passive, reducing maintenance complexity and cost.
3. Service transparency: Highly transparent to data format, rate, wavelength, and protocol; supports a variety of different services.
4. High reliability: Fiber optic cables are immune to electromagnetic interference, ensuring stable connections.
5. Future scalability: Capacity can be easily expanded by adding more wavelengths or using more advanced modulation technologies.
Market Importance
FTTH, as a mainstream broadband access technology, holds strategic significance for the digital economy:
1. Digital economy infrastructure: Provides high-speed, stable network infrastructure for emerging technologies such as 5G, cloud computing, and IoT.
2. Large market scale: The global FTTH market was about $120 billion in 2023, expected to surpass $280 billion by 2030, with a compound annual growth rate (CAGR) of 12.8%.
