Quantum-Safe Security
Adtran
Recent technological advancements have troubled the data security world. The emergence of quantum computers – machines able to leverage the properties of quantum physics to store data and perform computations – is set to have a catastrophic impact on the standard encryption protocols that have always successfully safeguarded the integrity of our data. The introduction of large-scale quantum computers will make almost all key-exchange protocols in use today susceptible to quantum attacks, resulting in data vulnerability that could threaten every aspect of our lives.
Ensemble Edge Cloud
Adtran
As demand grows for AI-driven applications and agile service delivery, operators and enterprises need flexible compute infrastructure that can scale quickly and deploy easily. Ensemble answers that call with a unified, automation-ready platform built for performance, security, orchestration and seamless scalability across single-node and multi-node environments.
Ensemble Cloudlet and EdgeView components provide flexibility, lower power consumption, small footprint and the ability to run whatever cypher solution you want (even in-house cyphers) or multiple instances in a single device.

Open Optical Networking
Adtran
Our portfolio is the ideal route to the benefits of openness. Now customers can deploy a turnkey integrated solution from one trusted and highly experienced vendor which is also fully disaggregated and primed to work with third-party technologies.
Timing & Synchronisation
Adtran
We’ve been pioneers of network synchronization technology for over 75 years. Our innovative solutions assist enterprise organizations, governmental institutions and mobile network operators to overcome major challenges, whether that be meeting stringent requirements for frequency and phase synchronization or addressing urgent footprint, power consumption and sky view limitations. Our devices support the industry to address these issues while monitoring and assuring timing with stringent accuracy.
Network Infrastructure Assurance
Adtran
Optical fibers carry huge amounts of bandwidth, representing thousands or even millions of concurrent end-customer services. Any disruption of a fiber link can have tremendous impact. And yet fibers are frequently not monitored at all, with service providers relying entirely on service layer alarms to detect failures. This results in time-consuming and expensive fault isolation. What's more, service unavailability creates frustrated customers. This can easily be avoided by fiber assurance solutions. In-service fiber monitoring is an efficient way to instantly detect any fiber degradation, triggering countermeasures even before services are affected.
