Link: Lightwave – Making the case for WDM-PON

It appears to me that the only people touting the benefits of WDM PON are WDM PON vendors. The reality is it requres 2x the optics of standard PON for no tangible benefit to carriers. What am I missing here?

  1. fwiw, France Telecom thinks they can save money with WDM-PON. Fewer local exchanges and future-proofed bandwidth, they’re saying. (There’s also a tax savings … for the sake of the WDM guys, I hope that’s not the majority of the savings.)
