This paper compares the incremental cost of CDC features in super-channel based and wavelength based ROADM architectures. A real world network model analysis shows fewer network components and less incremental cost with super-channel CDC ROADM.
The goal of long haul DWDM transmission is to deliver error-free digital information at extremely high data rates and over very long distances, ideally without the need for regeneration of the signal. Forward error correction (FEC) is a method of encoding a signal with additional overhead information so that optical receivers can detect and correct errors that occur in the transmission path. The latest...
This paper evaluates the impact of SD-FEC technology upon network design and economics in a long haul optical transport network. The network study shows that the SD-FEC technology not only reduces the TCO (total cost of ownership) but also simplifies the network design. A real world network model is utilized to quantify and compare results.
