SDH a PDH
SDH systems are used as a high-capacity optical fiber transmission medium. Today, they are being replaced by new technologies, but SDH networks will still be operational for several years.
PDH is an older technology used in digital networks for lower speeds. This technology still persists mainly in technology networks.
