Optical fiber propagation delay

WebThe transit time for signal propagation through an optical fiber of length . is: = á Ò Å Ö, (1) where L is the fiber length, ng the group index of the propagating mode and c is the speed of light in vacuum. The change in transit time with temperature normalized to the fiber length (Thermal Coefficient of Delay, TCD) is then expressed as: = 5 Å WebThis delay is determined by the signal “group velocity” – the speed of signal propagation in the fiber which depends upon the fiber group index. Where, vgis the group velocity (e.g., m/s) c is the speed of light in vacuum space (2.997925 x 10 8m/s), and n gis the group index.
