Fiber-optic communication
OverviewParametersBackgroundApplicationsHistoryTechnologyComparison with electrical transmissionGoverning standards
Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of MHz·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. For example, a common multi-mode fiber with a bandwidth–distance product of 500 MHz·km could carry a 500 MHz signal for 1 km or a 1000 MHz sig
