Support for existing technological networks<\/span><\/h2>\n

SDH systems are used as a high-capacity transmission medium via optical fibers. Today, they are being replaced by new technologies; however, SDH networks will remain in operation for several more years. PDH is an older technology used in digital networks for lower speeds. This technology currently persists mainly in technological networks. <\/span><\/p>\n

As part of our solutions, we continue to provide PDH and SDH-based communication solutions, which we maintain as part of our product support and delivered solutions. Leveraging our experience, we offer technology and service migration to new technologies to help customers achieve the most efficient migration possible. <\/span><\/p><\/div>\n\t\t\t<\/div>\n\t\t\t<\/div>
