Fiber optic testing encompasses the processes, tools, and standards used to test fiber optic components, fiber links, and deployed fiber optic networks. This includes mechanical and optical testing of individual elements and extensive transmission testing to verify the integrity of complete fiber optic network installations.

Fiber optics has become the world’s leading means of communication transport. The increasing diversity of fiber optic applications has highlighted the need for technician training as well as versatile, easy-to-use solutions for testing.

Since its inception in the 1970s, fiber optic networks have continued to evolve and spread.

The emergence of 5G technology, submarine networks, and fiber-to-the-home (FTTH) networks has highlighted the importance of robust fiber optic testing and monitoring. VIAVI offers an unparalleled legacy of expertise, reliability, and collaboration spanning more than 80 years that has resulted in the industry’s leading fiber optic test solutions.

Considering the size and complexity of today’s fiber optic networks, productivity is no longer optional. Efficiency must start in the laboratory and extend to construction and maintenance. VIAVI has a fully integrated portfolio of cloud-based fiber optic test instruments, software and services that offer flexibility and interoperability. The next generation of fiber optic test tools today provides faster, easier-to-use, and more power than ever before.

Why is it necessary to test fiber optic networks?

Industry standards and warranty requirements make fiber optic networks unavoidable, but there are many more reasons why fiber optic networks should be tested and monitored for performance.

The market demand for bandwidth has led to an increase in the size and complexity of fiber optic networks. The architecture of passive optical networks (PON) , dense wavelength division multiplexing (DWDM) , and other advances have introduced more Fiber optic cable segments and insertion loss locations, even as performance requirements increase and service budgets increase. losses decrease. Comprehensive and accurate testing at all levels and phases of networks can ensure customer satisfaction and a clear advantage over the competition. Despite the best intentions of the most highly trained technicians, the delicate nature and scale of fiber optics can be unforgiving in terms of contamination, microbends, and connector damage. Dirty connections continue to be the main cause of fiber optic network failures. By performing extensive testing on networks before they go live, any defects or damage can be proactively detected and repaired.
