kupariverkkoon

Kupariverkkoon, meaning "copper network" in Finnish, refers to the traditional telecommunications infrastructure primarily utilizing copper wires to transmit voice and data signals. This technology formed the backbone of telephone and early internet services for many decades. Copper networks are characterized by their physical cabling, typically installed underground or on poles, connecting individual homes and businesses to telephone exchanges and, later, to wider internet networks. These networks employ electrical signals modulated to carry information. The data transmission capabilities of copper networks are limited compared to newer technologies like fiber optics, with speeds and bandwidth being constrained by factors such as distance from the exchange and the quality of the copper lines. Despite these limitations, copper networks have historically been cost-effective to deploy and maintain, making them a widespread and familiar telecommunications medium. Many legacy systems still rely on copper infrastructure, though there is a global trend towards upgrading to fiber optics for enhanced performance and future-proofing.
