ADVA ALM 16 Advance Link Monitoring Video Training - Part 1


The Adva fiber assurance configuration we have in our labs consists of a single ADVA ALM16 which is terminated on port 1 to a 100 Km fiber spool configuration. We have two fiber spools of 50 Km each, connected via a patch panel, with an Adva reflector at the end. The ALM is running on software release version of 3.1.2 This configuration will allow us to shoot the 100 Km using the OTDR, create a fingerprint of the fiber characteristics and then monitor the fiber, providing live feedback to changes in those characteristics. This service runs at 1650nm, outside of the traffic carrying spectrum, so it will remain non-intrusive to existing traffic during its operation.

Without fiber monitoring, high-bandwidth services are always at risk of disruption, often with significant negative impact on customers. As soon as service providers invest in a proactive solution that measures the integrity of their fiber plant, they can efficiently isolate faults and take immediate targeted action. This dramatically shortens repair cycles and avoids unnecessary truck rolls. So why have many service providers been slow to implement in-service fiber monitoring solutions until now? In the past, fiber testing technology was designed for reactive measurement, while proactive solutions often failed to meet the cost and practicality requirements of many networks. Now a technology exits to address this urgent need.

ADVA’s ALM is a vital tool for service providers aiming to deliver superior performance. Designed for maximum power efficiency, it provides real-time, in-service fiber monitoring of the entire optical plant, enabling operators to know immediately if and where issues arise. With the ADVA ALM, operators can avoid unsuccessful repair attempts, prevent outages and enhance customer experience. This simple solution requires no active, onsite equipment at the remote site as it can be configured to passively monitor access services. Eliminating active demarcation further reduces cost and frees operators to deploy the ADVA ALM in even the most extreme environmental conditions. 

At WWT, we can help you evaluate this equipment through a series of scenarios, utilizing the ALM in our Advanced Technology Center (ATC). We have a simulated fiber route which allows us to showcase the OTDR and live fingerprint functionality
