"Optical fiber replaces copper" refers to the trend in the telecommunications industry where optical fiber communication gradually replaces traditional copper wire communication.
Specifically, "optical fiber" refers to the widespread use of fiber optic technology, which offers higher transmission speeds and longer transmission distances compared to copper wires. Therefore, optical fiber has become the main medium for modern communication networks, while "copper" refers to the gradual reduction or phasing out of traditional copper wire communication (such as telephone lines and ADSL broadband).
The reasons for this transition are due to the clear advantages of optical fiber over copper wire in several aspects:
- Faster transmission speeds: Optical fiber has much higher bandwidth and can support higher data transmission rates.
- Longer transmission distances: Optical fiber experiences less signal attenuation, making it suitable for long-distance transmission.
- Stronger resistance to interference: Unlike copper wires, optical fiber is not as susceptible to electromagnetic interference, ensuring more stable signals.
- Higher capacity: Optical fiber can carry much larger data volumes, catering to the demands of modern internet and big data.
As a result, with the advancement of optical fiber technology, more and more communication networks and internet infrastructures are adopting fiber optics to replace copper wires, in order to meet the increasing demand for high-speed communication.
