Fibre Optic Loss Dispersion and Power Budget

  • Course Overview

In an optical fiber medium, light rays travel in jagged lines causing signal loss or dispersion. Higher-order mode loss results when light traveling in the fiber core is radiated across the fiber cladding. All these factors limit the transmission distance of the fiber. To make sure the fiber-optic connection has enough power for correct operation, you need to calculate the power budget of the link. This course begins with an explanation of the various losses in optical fibers that contribute to link loss. This is followed by a description of how to measure the total loss in an optical fiber, while all types of losses that must be considered.
