What are the effects of total dispersion on the fiber optic communication system?

Total dispersion can limit the data rate of a fiber optic communication system. As the data rate increases, the pulse width decreases. If the pulse width becomes comparable to or less than the total dispersion, the pulses can overlap, causing inter-symbol interference (ISI). This can degrade the signal quality and limit the system’s data rate. Total dispersion can also limit the reach of a fiber optic system. Even if the data rate is not very high, for long-haul systems, the accumulated total dispersion can become significant and lead to system impairments. Unlike chromatic dispersion, which is deterministic and can be compensated for, total dispersion is a stochastic phenomenon, which means it varies randomly. This makes it challenging to compensate for total dispersion in a fiber optic system.

How to Calculate Total Dispersion?

Total Dispersion calculator uses Dispersion = sqrt(Fiber Rise Time^2+Pulse Spreading Time^2+Modal Dispersion Time^2) to calculate the Dispersion, Total Dispersion refers to the cumulative effect of all types of dispersion present in the fiber, which can cause the spreading of optical pulses as they travel along the fiber. The total dispersion is often calculated as the sum of, “Total Dispersion” refers to the cumulative effect of all types of dispersion present in the fiber, which can cause the spreading of optical pulses as they travel along the fiber. The total dispersion is often calculated as the sum of Modal Dispersion, Chromatic Dispersion and Polarization Mode Dispersion. Dispersion is denoted by t_t symbol.
