Passive optical networks (PONs) are a fiber-optic access technology that can be used for residential and business access, and also for certain backhaul applications and data communications.
An optical attenuator is a passive optical device that has a function opposite to that of an optical amplifier. It contains optical absorption materials and is used to reduce the power of optical signals in
In the PON (Passive Optical Network) system, calculating optical attenuation and transmission distance can be a tricky thing to deploy FTTH.
Attenuation in optical fibers occurs when the light intensity is reduced as it propagates through the fiber. It is a type of optical loss and it limits the distance over which it can travel.
