Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only.
Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the
data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

1. Linewidth (Δν) is calculated using this formula: Δν = ΔRIN(f){16π(Dλ2L/c)2f2}-1
Where: D = fiber dispersion; L = fiber length (65 km); C = velocity of light in free space (3.00E+8); λ = opt center wavelength ΔRIN(f) =
RIN through fiber (RIN65km – RIN0km); f = the measurement frequency (860MHz)
