Theoretical delay in fiber
WebbIn the actual application of the delay line, there are often different latency requirements for signals based on different situations. In this way, a single and fixed delay line cannot meet this requirement. Based on this, you can use the optical switch to select the length of the delayed optical fiber to obtain a variable fiber delay line. WebbTo calculate the required fiber length to obtain a specific time delay, use the following formula: L = c Δt / n where c is the speed of light in vacuum, Δt is the desired time delay, …

WebbOptical Fiber Loss and Attenuation The attenuation of an optical fiber measures the amount of light lost between input and output. Total attenuation is the sum of all losses. Optical losses of a fiber are usually expressed in decibels per kilometer (dB/km). The expression is called the fiber’s attenuation coefficient α and the expression is Webb9 juli 2015 · FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal.
