WebMay 2, 2010 · The optical transmission system design1–5 involves accounting for different effects that may degrade the signal during modulation, propagation, and detection processes. The transmission quality is assessed by the received signal-to-noise ratio (SNR), which is the ratio between signal power and noise power at the decision point. WebTransmission is a measure of throughput and is given as a percentage of the incident light. IR materials are usually opaque in the visible while visible materials are usually opaque in the IR; in other words, they exhibit nearly 0% transmission in those wavelength regions.
