Add GPON and XGS-PON capability at a compatible Omada PON OLT optical interface with the DS-PMA-COMBO C+ combo OLT SFP optical module. It combines support for both PON standards in one SFP-format optic, allowing the OLT design to use the required PON technology without changing the module form factor. The module is intended for the OLT side of a passive optical network rather than for subscriber-end equipment. This optic fits PON deployments where the access network may require GPON service, XGS-PON service, or a migration path that must account for both standards. Network engineers can match the module to the OLT interface and the optical-class requirement of the planned PON segment. Its compact SFP format preserves the serviceable, modular optical interface used in OLT hardware. What distinguishes this module is its combo support for GPON and XGS-PON together with the C+ optical classification in its ordering designation. That combination matters where a single-purpose GPON or XGS-PON optic would not meet the required network standard. Select it for an Omada PON OLT configuration that explicitly calls for a combo OLT SFP module and C+ class optics.
