Attenuation quantifies in decibels per kilometer, with single-mode fibers exhibiting minimal 0. 15dB/km reductions at 1550nm. Wavelength impacts attenuation, evidenced through testing. In fiber-optic communication, a single-mode optical fiber, also known as fundamental- or mono-mode, is an optical fiber designed to carry only a single mode of light - the transverse mode. The following table depicts typical optical attenuation for various fiber types. This allows for greater bandwidth and longer transmission distances compared to multi-mode fibers. All three fiber types are characterized as “ low‑water peak ”, meaning the maximum attenuation requirement at 1383 nm is equivalent to the maximum attenuation specified at 1310 nm. This constraint eliminates the concern that the fiber will have high loss in the 1360 nm to 1460 nm band caused by OH. There are three wavelength windows for 10G optical module communication applications, namely the 850nm window, 1310nm window, and 1550nm window.
