Copper Networks and FTTH in Africa
Since the introduction of telecommunication systems in the 20th century, copper networks have been the backbone of the majority of communication infrastructure globally. Africa, with its vast landscape and varied levels of development, hasn’t been an exception to this trend.
However, as with all technology, copper networks have their limitations and are gradually being replaced by more advanced systems. In the context of telecommunication, these typically include fiber-optic networks like FTTH (Fiber to the Home), wireless broadband technologies, satellite communication systems, and more. These advanced systems offer higher data transmission speeds, greater reliability, and are often more sustainable and scalable than their copper-based predecessors.
How do Copper Networks Work
Copper networks primarily utilize twisted pair copper cables (like the ones used in traditional telephone lines) to transmit data. The analog voice data from a telephone is converted into electrical signals which travel over these copper lines. Similarly, for internet data, the modems modulate and demodulate digital data into electrical signals suitable for the copper medium.
Weaknesses and Disadvantages of Copper Networks
- Limited Bandwidth: Copper networks, especially those based on older ADSL technology, can only provide limited data speeds. This restricts the kind of internet services and quality of calls available to users.
- Attenuation and Noise: Over longer distances, copper cables suffer from signal degradation. This means that users farther from the central office or exchange experience slower speeds and poorer quality.
- Maintenance: Being a physical medium, copper is prone to wear and tear, environmental degradation, and even theft (due to the resale value of copper).
- Lack of Sustainability: Copper mining, a necessity for these networks, has environmental impacts including habitat destruction and pollution. Many mines in Africa have been cited for human rights violations and environmental harm.
- Exploitation of Natural Copper Resources: Africa holds a significant portion of the world’s copper reserves. This has led to over-extraction in some areas, often without fair compensation or benefits to local communities.
Transition to FTTH
FTTH involves running fiber optic cables directly to individual buildings like residences, apartment buildings, and businesses. The advantage of fiber optics is the use of light signals instead of electrical ones, offering vastly higher bandwidths and less signal degradation over long distances.
Connection between Copper Networks and FTTH
While copper networks have served as the primary means of telecommunication for decades, FTTH is rapidly becoming the preferred choice for several reasons:
- Superior Speed: Fiber can deliver gigabit speeds, a significant upgrade from the typical speeds of copper-based DSL.
- Reliability: Fiber optic cables are less susceptible to environmental conditions and physical degradation.
- Future-Proof: Fiber networks can be upgraded easily with newer technology without replacing the entire infrastructure.
