PON Interoperability with Genexis

Fiber broadband networks rely on Passive Optical Networks (PON) technology, where ONTs and OLTs must communicate flawlessly to ensure reliable service.
While international standards like ITU-T and BBF.247 set the foundation, real-world deployments reveal hidden complexities: vendor-specific software, unique managed entities, and configuration differences.
These differences – “small little things” - often lead to interoperability problems between OLT and ONT and create the risk of vendor lock-in.

Optisis, together with Genexis, removes this issue. Our approach ensures operators freedom of choice:

• No more being tied with ONTs to a single vendor OLT.
• Flexibility to select any OLT vendor that best fits their network needs — today and in the future
