Mobile network

In today's rapidly evolving business environment, successful companies need to keep their network infrastructure up to date. New devices and services need to be tested and certified for quality, reliability and security before they are integrated into the active live infrastructure to avoid disruptions or outages. One of the means to carry out the test procedures in a timely manner is the use of automated test environments. The areas of application for laboratory automation are diverse, ranging from RAN testing to transport and core network testing.

Whereas previously time-consuming, manual test procedures were often necessary to verify network devices, an automated, user-configurable fiber optic level can now be used, allowing test runs or reconfigurations to be carried out within seconds instead of hours or days, resulting in time and cost savings.

By deploying RF-over-Fiber (RFoF) modules to convert signals from RAN radios into fiber optic signals and utilising fiber optic switching, labs can fully leverage the solution's end-to-end benefits. This approach enables much greater transmission distances with significantly lower losses from Device Under Test (DUT) to test equipment. Additionally, fiber optics are extremely lightweight, compact, and have a better bend radius than coaxial cables, making them easier to deploy. Each end of the fibers is equipped with RFoF functional blocks to convert optical signals back to RF. HUBER+SUHNER’s modular RFoF system is designed to meet the highest transmission performance requirements, particularly for the highly dynamic range of test and measurement applications and automated, performance-optimised system adjustments. 

In transport and core networks, new devices or even completely new network structures must be validated promptly or network problems must be reproduced, diagnosed and rectified quickly. Test labs have to simulate scenarios in order to find effective solutions for the live network.  

Our POLATIS optical circuit switch is the heart of the solution for laboratory automation. Thanks to this solution, you are able to flexibly connect and measure optical network components and carry out tests in a test environment. Our solution enables continuous testing of multiple devices remotely, eliminating the need for physical presence and manual re-patching. This not only reduces labor costs but also frees you from tedious manual tasks.
