Decibels per kilometer to decibels per mile
Type a value in dB/km to get it in dB/mile instantly.
0.3219dB/mile
That's about the same as single-mode fiber at 1550 nm. After about 50 km only a tenth of the power is left.
What it means
How lossy is that?
Cable loss rises with frequency, so a datasheet figure always belongs to a stated frequency. Fiber loss depends on the wavelength instead.
The math
How to convert dB/km to dB/mile
To convert decibels per kilometer to decibels per mile, multiply by 1.60934.
Example: 0.2 dB/km × 1.60934 = 0.321869 dB/mile.
In the other direction, 1 dB/mile = 0.621371 dB/km.
