Worldwide, operators of all types are turning up an increasing number of passive optical networks. Whether they are telcos transitioning off their legacy DSL platforms, overbuilders trying to reach multiple dwelling units, cable operators targeting greenfield builds or, increasingly, service providers entering currently underserved rural markets, there is an explosion in new fiber build activities. Given the timing to the market, these operators face a decision. Should they continue embracing the 1Gig (or 2.5Gig) GPON and EPON networks, or should they move to the newer 10Gig platforms – either 10G-EPON or XGS-PON? I was just recently talking to a small operator and was surprised to learn they were still building out with 1Gig PON platforms. Let's look at what might be involved in making such a decision, and why I believe 10Gig PON is the right choice.
