Yksimodeinen

Yksimodeinen refers to a single-mode fiber optic cable. This type of fiber optic cable is characterized by its small core diameter, typically around 9 micrometers. This small core allows light to travel in only one mode, or path, which significantly reduces modal dispersion. Modal dispersion is a phenomenon that causes different modes of light to travel at slightly different speeds, leading to signal degradation over long distances. Because single-mode fiber minimizes modal dispersion, it is ideal for transmitting data over very long distances, making it suitable for telecommunications networks, undersea cables, and high-speed internet infrastructure. The light source used with single-mode fiber is usually a laser, which can be precisely focused into the small core. Compared to multi-mode fiber, single-mode fiber generally offers higher bandwidth and lower attenuation. The manufacturing process for single-mode fiber is more precise due to the very small core size.
