1. Telecommunications and Internet:
• Optical fiber cables form the backbone of the global internet, connecting intercontinental data centers and communication base stations.
• Submarine optical cables (such as the Asia-Pacific Submarine Cable (APCN2)) handle cross-border data transmission, covering tens of thousands of kilometers.
2. Home Broadband (FTTH):
• Fiber to the Home (FTTH) technology directly connects optical cables to homes, providing 100 Mbps or even gigabit broadband.
• Fiber broadband coverage has exceeded 90%, driving high-bandwidth applications such as 4K video and cloud gaming.
3. Data Centers:
• Multimode optical cables are used within data centers to connect servers and storage devices, supporting cloud computing and big data processing.
• Single-mode optical cables are used for long-distance interconnection between data centers.
4. Industry and the Internet of Things (IoT):
• Optical fiber cables provide stable and high-speed communication support in smart manufacturing, power monitoring, and transportation systems.
• Their anti-interference characteristics are suitable for complex environments such as factories and railways.
5. Medical and Scientific Research:
• Fiber optics are used in medical equipment such as endoscopes and laser surgery.
• The scientific research field utilizes fiber optics to transmit massive amounts of experimental data.
