Metropolivõrgud

Metropolivõrgud, a term often translated as metropolitan networks or metro networks, refers to a telecommunications network infrastructure that spans a metropolitan area. These networks are designed to provide high-speed data, voice, and video services to businesses, residences, and other organizations within a city or a closely connected group of urban centers. They typically utilize fiber optic technology to achieve the necessary bandwidth and low latency for modern communication needs.

The primary purpose of a metropolivõrgud is to connect various points within a metropolitan area, such as local area networks (LANs) of different companies, internet service provider (ISP) points of presence, and data centers. This allows for efficient and rapid data exchange between these entities without relying on long-haul networks that would introduce unnecessary delays and costs. They form a crucial layer in the overall telecommunications ecosystem, bridging the gap between local access networks and the broader internet or private wide area networks (WANs).

Key characteristics of metropolivõrgud include their high capacity, typically measured in gigabits or terabits per second, and their scalability, allowing for expansion as demand grows. They often employ dense wavelength-division multiplexing (DWDM) technology to transmit multiple signals over a single fiber optic strand, maximizing the use of existing infrastructure. The deployment of metropolivõrgud is essential for supporting services like cloud computing, high-definition video streaming, and real-time data analytics, underpinning the digital economy of a modern city.
