Mathau o Geblau Fiber Optic

Mae ceblau ffibr optig yn llinellau trawsyrru sy'n defnyddio golau fel y dargludydd, ac mae ganddynt fanteision craidd megis cyflymder uchel (yn agosáu at gyflymder golau), lled band mawr (trosglwyddiad data lefel TB-cynnal), a-ymyrraeth gref (heb ei effeithio gan feysydd electromagnetig). Mae eu swyddogaethau craidd yn cynnwys: 1. Cyfathrebu cyflym (latency<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.
