What is acceptable dB loss for fiber?

For multimode fiber, the loss is about 3 dB per km for 850 nm sources, 1 dB per km for 1300 nm. (3.5 and 1.5 dB/km max per EIA/TIA 568) This roughly translates into a loss of 0.1 dB per 100 feet (30 m) for 850 nm, 0.1 dB per 300 feet(100 m) for 1300 nm.

How to Calculate Fiber Attenuation Coefficient?

Fiber Attenuation Coefficient calculator uses Attenuation Coefficient = Attenuation Loss/4.343 to calculate the Attenuation Coefficient, The Fiber Attenuation Coefficient formula is a measure of the rate at which an optical signal decreases in power as it propagates through an optical fiber. It represents the amount of signal loss per unit length of the fiber and is typically expressed in decibels per kilometer (dB/km) or decibels per meter (dB/m). Attenuation Coefficient is denoted by α_p symbol.

How to calculate Fiber Attenuation Coefficient using this online calculator? To use this online calculator for Fiber Attenuation Coefficient, enter Attenuation Loss (α) and hit the calculate button. Here is how the Fiber Attenuation Coefficient calculation can be explained with given input values -> 0.640111 = 2.78/4.343.
