Economics of Time and Wavelength Domain Multiplexed Passive Optical Networks
Passive Optical Networks (PONs) are being widely considered as a means to implement Fiber-To-The Home (FTTH) and deliver broadband access to business and home users. However, technical and consequently regulatory and economic complexities arise in light of their deployment. In this paper, an evaluation of the business prospects of Time Division Multiplexed (TDM) and Wavelength Division Multiplexed (WDM) PON architectures for FTTH deployments under different rollout conditions is performed, based on the ECOSYS techno-economic methodology and tool. The importance of various cost components (fiber installation, optoelectronic components, etc.) is discussed.
