Fiber assurance solutions. Improving network availability and reducing opex

Fiber optic networks provide a cost-effective and reliable way to transmit enormous amounts of data. However, fiber cables can be damaged in many ways, creating a headache for network operators who need to maintain service availability for broadband subscribers and critical infrastructure such as power grids. Rapidly identifying the location and root cause of a fiber failure is crucial for seamless network operations, but traditional monitoring solutions are reactive and designed for post-failure measurement, making them inadequate for the task.


Adtran’s ALM offers proactive, in-service fiber monitoring, helping CSPs improve network availability and reduce operational costs. By merging optical components with digital signal processing, ALM enables centralized, non-intrusive monitoring of fiber networks. The platform identifies and locates fiber faults and issues instant, detailed alerts about impending issues so maintenance teams can take immediate and targeted action to minimize downtime. What’s more, ALM’s deep PON assurance capability ensures precise and affordable monitoring of individual PON network components without the need for reflectors.
