High resolution TV, video streaming and surfing the internet: if all of these activities take place at the same time in one household, traditional copper lines soon reach their limits. This is why the future belongs to fiber optics, according to Fabrice Allegro, Sunrise's Executive Director Marketing. In comparison with traditional copper networks, fiber optics increases bandwidth significantly and enables data transmission rates of up to 1GB/s for downloads and uploads.
Already available in numerous regions
As the largest private telecommunications provider in Switzerland, Sunrise offers its customers a comprehensive range of fiber optic services. For this purpose, Sunrise works with Swiss Fibre Net, a consortium of local power utility companies. The Sunrise fiber optic network is currently available in the cities of Basel, Bern, Geneva, Lucerne, Winterthur, Zurich and in the cantons of Fribourg, St. Gallen and the sub-cantons of Appenzell.
As the name indicates, fiber optic technology consists of optical (or glass) fibers. The width of these fibers is roughly equivalent to that of a human hair. In contrast to traditional telephone cables made of copper, the data is sent along a fiber optic cable not electrically but as pulses of light. The transmitter uses a laser to shine light into the fiber optic cable and the signal is sent at the speed of light to the receiver. Once received, the light impulses are converted back into electrical signals. This means that users really are surfing at the speed of light.
