Industry Contemplates WDM-PON Technology

by Meghan Fuller fibers.org News, 11 Sep 2006 Wavelength-division-multiplexed passive optical networks (WDM-PONs), which offer point-to-point delivery of one wavelength per customer, may eventually supply an optimal fibre-to-the-home architecture. WDM-PON has been positioned as a possible successor to Ethernet/gigabit PON fibre-to-the-home implementations. Though technically feasible, it is still considered too expensive for widespread residential deployment. Some wonder if, at least in the near term, the technology is better suited for commercial service delivery. And one analyst even suggests that WDM-PON might be most suitable for applications typically served by coarse wavelength division multiplexing. Read more
