Attenuation vs. Wavelength

Kusintha kwakukulu kwapang'onopang'ono kuchokera pawindo

Kupaka Kwazinthu

Mfundo discontinuities

Kuyimitsa mfundoosapitirira 0.02dB pa 1310nm kapena 1550nm.

Attenuation kufanana

Ngati Utali wa CHIKWANGWANI ≥2.15km, mtengo wosiyana wagawo lochepetsetsa komanso kuchepa kwapakati sikupitilira 0.03dB/km.
