Its bandwidth efficient modulation yields significant cost savings by providing higher data rates using lower frequency optoelectronics. Network providers can deliver signals that are data rate and protocol independent. This allows rapid, independent provisioning of subcarrier channels. Additionally, only one network element needs to be provisioned in order to reconfigure the network. It is possible to provision xDSM waveforms on any or all of the wavelengths of a DWDM network.
Greater reach is achieved on dispersion-limited channels.
While xDSM technology has great potential, risk factors exist that may limit product performance and broad market acceptance. Trade-offs among cost, size, performance, and power requirements will continue throughout the product development cycle. Critical technology development is ongoing for fast data conversion, advanced digital signal processing architectures, and system dynamic range.
