The main difference between fiber and copper cable lies in the way they transmit data. Copper cable uses electrical signals to transmit data, while fiber optic cable uses light signals. This fundamental difference has several implications:
Bandwidth: Fiber optic cable can transmit data at much higher speeds than copper cable. This is because light signals can travel faster than electrical signals. This makes fiber optic cable ideal for high-speed internet connections, streaming video, and other bandwidth-intensive applications.
Distance: Fiber optic cable can transmit data over much longer distances than copper cable. This is because light signals experience less attenuation (weakening) over distance than electrical signals. This makes fiber optic cable ideal for long-distance communication, such as in telecommunications networks.
Immunity to electromagnetic interference (EMI): Fiber optic cable is immune to EMI, while copper cable is susceptible to it. This means that fiber optic cable can be used in environments where electromagnetic interference is a concern, such as near power lines or in industrial settings.
Cost: Fiber optic cable is typically more expensive than copper cable, both in terms of the cable itself and the equipment needed to install and maintain it. However, the higher bandwidth and longer distance capabilities of fiber optic cable can make it a cost-effective choice for certain applications.
In summary, fiber optic cable offers several advantages over copper cable in terms of bandwidth, distance, and immunity to electromagnetic interference. However, it is also more expensive, and may not be the best choice for all applications.
What are the advantages of copper cable?
1.Low resistivity of copper core cable: the resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable.
2.The copper core cable has good ductility.
3.The high strength of copper core cable: the allowable stress under normal temperature can reach 20 for copper and 15.6kgt/mm2 for aluminum.
4.Anti-fatigue of copper core cable: aluminum is easy to break after repeated bending, while copper is not easy to break.
5.Copper core cable has good stability and corrosion resistance: the copper core is resistant to oxidation and corrosion, while the aluminum core is vulnerable to oxidation and corrosion.
