Questions & Answers

Q: Why is Sonic WDM considered a cost-effective solution?

Sonic WDM is cost-effective due to its simplicity and low cost compared to TDM solutions. Optical pass-through and grooming of traffic streams further reduce costs.

Q: How is traffic groomed in Sonic WDM networks?

Traffic can be grouped into light paths to avoid dropouts. The termination of traffic streams should be in a part of the network to optimize costs.

Q: What are the characteristics of SONET rings in network design?

SONET rings can be either uni-directional or bi-directional, imposing additional constraints on the use of light paths. SONET rings can also be interconnected and routed from one ring to another.

Q: What elements are involved in the Sonic ADM network design?

The ADM network design consists of high-speed ADM lines, lower-speed interfaces, interconnections, optical amplifiers, optical switches, and digital cross-connects.

Summary & Key Takeaways

• Sonic WDM, based on wavelength routing, is a cost-effective alternative to TDM solutions in optical networking.

• Optical pass-through in the network allows for large savings by reducing the number of TDM line terminals.

• Traffic grooming through light paths can optimize network cost and consider higher layer needs, such as SONET.
