optikleistung

Optikleistung, also known as optical power, is a measure of the intensity of light transmitted through an optical fiber or emitted by an optical source. It is typically expressed in units of Watts (W) or milliwatts (mW), although decibel-milliwatts (dBm) are frequently used in telecommunications for their logarithmic scale, which simplifies calculations involving signal attenuation.

The concept of optikleistung is fundamental to optical communication systems, as it directly relates to the signal strength received at the other end of a fiber optic cable. Higher optikleistung generally results in a stronger signal, which can travel longer distances before becoming too weak to be detected reliably. Conversely, insufficient optikleistung can lead to signal degradation and errors.

Factors influencing optikleistung include the power output of the light source (e.g., a laser diode or LED), losses within the optical fiber due to absorption and scattering, and losses at connection points (connectors and splices). Measuring and managing optikleistung is crucial for ensuring the performance and reliability of fiber optic networks. It is a key parameter in system design, installation, and troubleshooting. Specialized instruments called optical power meters are used to accurately quantify optikleistung at various points in a system.
