AI Technical Summary

Benefits of technology

This technology allows an operator or researcher to simulate how well their equipment works at different levels of light output (W) without actually measuring it. It uses both gains/interference indexes from two types of sources - one being pure waves while another containing no interfering signals like background lights. By fitting these values with each other based on factors such as gain references and noise indices, we get more accurate simulations that help us make informed decisions about future improvements made during manufacture.

Problems solved by technology

This patents discusses how different types of signals may be combined together over long distances before being received on one or more Optical Networks called OXN networks. These signals often experience changes caused by factors like temperature fluctuations and external interference sources such as rainwater. To compensate for these effects, certain technical features were developed based upon mathematical models with varying degrees of precision. Existing methods use either analyzed simulations or numerically calculated values, but they cannot provide accurate data when there exist errors in the analysis model's settings.
