Perhaps you'd share some specifics? I certainly haven't worked on all of the PON systems that are out there, but the ones I have worked one didn't have (or I didn't find) a good way to separate traffic at layer 2 so that several operators could handle their own Layer 3 provisioning for customers on the same OLT.
Every PON OLT that I have touched has supported both vlan-per-customer (has scaling issues) and vlan-per-service configuration abstractions. There are other ways to do it too (double and triple tagging) but to keep it simple if one creates profiles along the lines of: SP1-VOIP SP1-VIDEO SP1-INTARWEBZ and repeats for sp2, sp3, etc... trunk out the top, split off vlans and backhaul as appropriate (choose wisely!) with appropriate QoS if you like, to equal access provider. Provisioning the ONT/ONU and the inter-provider interface to do so (REST XML? JSON? something else?) is left as an exercise to the implementer. Reading this: https://sites.google.com/site/amitsciscozone/home/gpon/gpon-vlans-and-gem-ports may prove informative for the GPON case. -r
