Optical Fiber Cable Testing

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

Fiber optics have emerged as the world’s leading communication transport medium based on 3 distinct advantages over copper-based infrastructure: reduced cost of operation in terms of power and maintenance, reliability and superior bandwidth/transmission speeds. The increasing diversity of fiber optic applications and point-to-point (PTP) and point-to-multi-point (PTMP) architectures highlights the need for technician training and versatile, user-friendly test solutions.

With the size and complexity of today’s fiber networks, productivity is no longer an option. Efficiency must begin in the lab and extend throughout construction, installation, and maintenance. ENVITEST has fully integrated test facility of fiber test instruments, software, and services that are flexible and interoperable.
