Fiiberoptilised kaablid on ülekandeliinid, mis kasutavad valgust juhina ja millel on peamised eelised, nagu suur kiirus (läheneb valguse kiirusele), suur ribalaius (toetab TB-taseme andmeedastust) ja tugev anti-häire (mida elektromagnetväljad ei mõjuta). Nende põhifunktsioonide hulka kuuluvad: 1. Kiire side (latentsus<1ms), suitable for real-time scenarios such as financial transactions and telemedicine; 2. Big data processing (single fiber capacity up to 100Tbps), supporting cloud computing and edge computing needs; 3. Long-distance transmission (80-100km without repeaters), ensuring high-quality cross-border communication. In home scenarios, Fiber to the Home (FTTH) technology can provide gigabit-level bandwidth (1Gbps+), perfectly supporting high-bandwidth applications such as 4K/8K video and cloud gaming. In the future, with the development of 5G and the Internet of Things, ultra-low-loss fiber (attenuation ≤0.15dB/km) will become the data artery for smart cities and autonomous driving.
