This is important for CWDM systems that use wavelengths at or near 1383nm. The specification calls for 1383nm attenuation to remain equal to or below the attenuation from 1310nm to 1625nm. Glass fiber's strength and reliability has been researched thoroughly. Thus the cables are generally designed to provide high tensile strength, crush resistance and to withstand temperature changes between -40°C and +70°C with attenuation changes as low as possible. Below this temperature, materials such as PVC or rubber may become brittle.
