Managing a PON network below the surface  

All technology devices talk with each other; think of a computer and its mouse or a TV and its sound system. All these devices need to communicate in harmony to function properly. We rarely think about how this works; it just operates seamlessly. Similarly, when deploying a Passive Optical Network (PON), an Optical Line Terminator (OLT) and an Optical Network Terminator (ONT) need to communicate with each other. Ideally, the interoperability (interop) should be seamless, thanks to the various PON standards (e.g., ITU-T, BBF.247). However, PON interoperability is like an iceberg. At the same time, the standards are visible above the surface, and much complexity lies beneath them, such as vendor proprietary managed entities, OLT software version specifics, and specific network configurations.

To ensure communication between the OLT and ONT, stay clear of locking into one OLT vendor

Lady talking letters

Communication between an OLT and an ONT can be compared to a language with many dialects. In theory, your country’s language is comparable to the PON standards. However, in practice, there are many different dialects, which makes it difficult for various dialects to understand each other. Similarly, each OLT talks in its own PON dialect, which is vendor specific. All will work fine if you stay with the same OLT and ONT brand forever. However, if you decide or are required to add another OLT vendor with its own specific PON dialect, the interop challenge begins. You start to encounter an OLT vendor lock-in, with multiple OLT and ONT brands that do not properly talk to each other.

Our award-winning software, TrueTalk, automatically detects the OLT dialect and adapts to the ONT, ensuring seamless interop with a single firmware version.

At Genexis, we strongly believe in the freedom of choice. Today, tomorrow, or in the distant future, you should have the freedom and flexibility to select the OLT vendor that best serves your needs. To make this possible and solve the interop challenges, we have equipped all our Genexis FiberTwist and FiberBox ONTs with our award-winning TrueTalk solution. This is what we call the ‘PON OLT Dictionary’. No matter what dialect the OLT speaks, TrueTalk will automatically detect the dialect and adapt accordingly – ensuring seamless interop with a single firmware version!
