Who Makes What: Optical Components 2004

Signal conditioning components measure and adjust variables such as signal power, gain across DWDM channels, and dispersion, to keep them within set limits. Components include optical channel monitors, variable optical attenuators (VOAs), gain-flattening filters/spectral equalizers, and dispersion compensators.
