ADVA ALM – rapid detection of optical cable disruptions and the determination of their locations.


Fiber assurance solution for lean operations – ADVA ALM

Fiber is a high-value asset. It transports huge amounts of data, generating significant revenue. Fiber failure demands immediate action but a lack of information about the nature of a problem often makes this impossible. In-service fiber monitoring solves this issue and our unique ALM does it with unrivaled efficiency.

Operations teams have one key objective: run a complex communication infrastructure as efficiently as possible. In the event of network failure, a root cause analysis should not require on-site field forces with expensive measurement equipment.

Giving customers higher bandwidth services should be possible without changing demarcation device. Gathering real-time information about the integrity of the fiber network should not require a costly new kit. Proactive fiber link monitoring solves those challenges. Our ALM is an in-service advanced link monitoring solution for highly precise, real-time monitoring of fiber links. It streamlines operational processes, shortens repair cycles and enables service-agnostic network demarcation.
