To implement the Dense Wavelength Division Multiplexing (DWDM) fiber in OMNeT++, we have to simulate an optical communication in which the numerous data signals are exchanged concurrently on various wavelengths through an individual optic fiber. DWDM is extensively used in telecommunications to raise the bandwidth of optical networks.
Below is the detailed guide on how to approach this in OMNeT++ with examples:
Steps to Implement DWDM Fiber in OMNeT++
Example Configuration
Here’s a simple example configuration for a DWDM fiber network in OMNeT++:
network = DWDMNetwork
sim-time-limit = 100s
[Config DWDMNetwork]
*.numNodes = 6
*.node[0].type = “OpticalTransmitter”
*.node[1].type = “OpticalTransmitter”
*.node[2].type = “OpticalReceiver”
*.node[3].type = “OpticalReceiver”
*.node[4].type = “OpticalMultiplexer”
*.node[5].type = “OpticalDemultiplexer”
# Define the wavelengths for DWDM channels
*.node[0].wavelength = “1550nm”
*.node[1].wavelength = “1551nm”
*.node[2].wavelength = “1550nm”
*.node[3].wavelength = “1551nm”
# Define the fiber link between multiplexer and demultiplexer
connections = [
{ srcNode = “node[4]”, destNode = “node[5]”, channelType = “DwdmFiberChannel” }
]
# Configure the multiplexer and demultiplexer
*.node[4].muxingAlgorithm = “DWDM”
*.node[5].demuxingAlgorithm = “DWDM”
# Define the links between transmitters, receivers, and MUX/DEMUX
connections += [
{ srcNode = “node[0]”, destNode = “node[4]”, channelType = “OpticalChannel” },
{ srcNode = “node[1]”, destNode = “node[4]”, channelType = “OpticalChannel” },
{ srcNode = “node[5]”, destNode = “node[2]”, channelType = “OpticalChannel” },
{ srcNode = “node[5]”, destNode = “node[3]”, channelType = “OpticalChannel” }
]
Example Scenarios
Considerations:
This setup demonstrates a simple implementation of Dense Wavelength Division Multiplexing (DWDM) fiber in OMNeT++ including snippet codes and additional consideration for further use. You can expand it further to include additional nodes, and more complex network topologies as needed.
