WebThe optical power budget is the minimum light energy required for transmitting signals successfully to the receiver through fiber optic fibers. The maximum length of a fiber … The optical power budget in a fiber-optic communication link is the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is available at the receiver. In optical power budget attenuation is specified in decibel (dB) and optical power in dBm.
