Tip of the Week – 05 Mar 2013
Tip of the Week:
As you plan this yearâ€™s fiber cable deployment, you may want to consider selecting your cableâ€™s optical fiber with a lower MAC ratio to help reduce microbending attenuation.
Microbending attenuation is the loss of optical signal power along a fiber cable length due to small (typically less than 1 mm) bends in a cableâ€™s optical fiber. These small fiber bends are caused by various environmental conditions and loads placed onto the cable.
The MAC ratio is the mode field diameter to cutoff wavelength ratio of a fiber, typically ranging from 6 to 8 for G.652 fiber. It was shown by Corning that a lower MAC ratio results in lower microbending attenuation. It also was shown that a larger fiber coating reduced microbending attenuation (250um, 500um, 900um).
