In late August Calix came to our site and tested their IPv6 support on the C7 platform for their upcoming 8.0 release. They tested both on GPON and VDSL2 using the N:1 (VLAN per service) approach. There were some issues that prevented all the CPE I had from working, but since then they've taken it back and completed that work. I've invited them back onsite to re-test so we can validate before they begin their controlled release.

In any such vendor choice, I'd say make sure that they have workable IPv6 before making any major investments. Otherwise, you've got a dead-end platform that won't serve you very well for very many years.
GPON deployment for FTTH tends to be, really, an Ethernet switch. There is just additional intelligence thrown in to keep the thing from being suicidal at Layer 2 for that many customers when doing typical consumer broadband. If you're using the GPON AN as as a regular switch, i.e., one VLAN per customer, then you can roll IPv6 to your FTTH customers just as you would on a Cisco Catalyst switch, for example. But most operators are using them for broadband deployments, and the split horizon mechanisms implemented as part of the Broadband Forum spec. for GPON make it unintuitive that v6 be supported off the bat for DHCP and PPPoE. Of course, this isn't rocket science, and just needs to be added in software - a problem many vendors are suffering from. As we do with all of them, keep pushing for support for the features you need in v6. Just make sure you don't buy a dud. Mark.
