In the case of muni systems, which are not-for-profit enterprises, one measure of “success” is defined as the level of their “take rate” – that is, the percentage of potential subscribers who are offered the service that actually do subscribe. Nationwide, the take rates for retail municipal systems after one to four years of operation averages 54 percent. This is much higher than larger incumbent service provider take rates, and is also well above the typical FTTH business plan usually requiring a 30-40 percent take rate to “break even” with payback periods.
