    Length of optical cable reserved in the preliminary budget

    To protect against deterioration of fiber or component performance, 3 dB of the power budget for each link is reserved as an aging margin. 5/125 �m fiber typically has an attenuation of 3. Estimate optical attenuation, received power, design margin, and maximum supported reach for a fiber path. The suggestions below can be used in Ethernet, Token Ring and FDDI installations. Sometimes the power budget has both a minimum and maximum value, which means it needs at least a minimum value of loss so that it does not.
