Information

Power equalization is a network theory term. Refers to the power level between various wavelength channels in a wavelength division multiplexed optical network due to various reasons. This difference may come from static wavelength division multiplexing transmission or dynamic optical conversion. 

12V 24V power equalization
In the wavelength division multiplexing transmission system, the power imbalance mainly comes from the non-flat characteristics of the optical amplifier gain and the nonlinear effect of the transmission fiber. Power equalization introduces optical cross-connect nodes and optical add/drop multiplexing in optical networks.
Power imbalance will cause relatively large damage to the performance of the system and limit the scale and capacity of the network. Therefore, it is necessary to adjust the power level of each wavelength channel to make it basically consistent. This is the task that power equalization needs to complete. For In large-scale optical networks, nodes generally have dedicated power equalization modules to adjust the power levels of each wavelength channel.
