ProLabs to unveil testing solution to detect, locate & report fibre faults


Leading optical transceiver specialist ProLabs will showcase its latest testing solution, which detects and locates breaks or faults in optical fibre cables at Broadband World Forum 2018, taking place in Berlin on October 23-25.

South Cerney-based ProLabs’ EON-NSV-OTDR quickly locates and reports any faults or issues within optical fibre networks enabling the right team to be dispatched for the related problem faster than before.

The product works by transmitting optical pulses into the fibre under test and extracts. From the same end of the fibre, light is scattered or reflected back from points along the fibre. The scattered or reflected light is measured and then analysed to locate the end of the fibre, the location and overall loss. This process allows engineers to detect if fibres are intact and to then deploy teams to fix the issues as and when they are found.

“Detecting problems within optical fibres is vital if a reliable network is to be maintained,” said Ray Hagen, Product Manager at ProLabs. “The information that the OTDR solution provides can report on the specific problem that has occurred and highlighting the approximate location, saving time and disruption to often critical and vital services. This solution is addressing the ever-increasing demand for reliable network requirements, and ProLabs is proud to offer such a product at a cost-effective price point.”

The EON-NSV-OTDR is  designed to allow for not just OTDR testing of the underlying optical circuit but also the layer-2 and layer-3 services that may be running over it. The solution contains custom hardware for the generation of test traffic, loop-back and analysis and can be configured to provide real-time monitoring of jitter and latency between the desired end-points in the network.
