kuparikaapeliyhteyksinä

Kuparikaapeliyhteyksinä refers to telecommunications and data transmission services delivered over copper wire infrastructure. This technology has been a cornerstone of global communication networks for over a century, providing voice and internet services to homes and businesses. Copper cables, typically twisted pairs of insulated copper wires, transmit electrical signals that represent voice or data.

The most common form of copper-based broadband internet is Digital Subscriber Line (DSL). DSL technology utilizes the existing copper telephone lines to transmit data at much higher frequencies than those used for voice calls, allowing for simultaneous internet access and phone service. Different variations of DSL, such as ADSL (Asymmetric DSL) and VDSL (Very High-speed DSL), offer varying speeds and performance levels, with VDSL generally providing faster download and upload capabilities over shorter distances.

While copper networks have served reliably for decades, their capacity is limited compared to newer fiber optic technologies. The distance from the telephone exchange or street cabinet to the customer's premises significantly impacts copper's performance; signal degradation increases with distance, leading to slower speeds. This limitation has driven the development and deployment of fiber-to-the-home (FTTH) networks, which offer substantially higher bandwidth and more consistent performance. Nevertheless, copper networks remain prevalent in many areas due to the significant investment required to replace them entirely. They continue to be a viable option for internet access, particularly in regions where fiber deployment is ongoing or not yet feasible.
