Optical attenuation is the gradual loss of flux (light intensity) as an optical signal travels through a fiber. Measured in decibels (dB), it''s the logarithmic ratio of the output power to the input
The attenuation factor is well known for all the types of glass used in long-haul fiber-optic cables; you can find it in the fiber manufacturer''s catalog. The unit decibel describes the ratio of the
Attenuation refers to the amount of signal loss as it travels down the fiber, typically expressed in dB/km. Losses can be caused by scattering, absorption, dispersion & bending.
To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission.
