DESCRIPTION

Verification that complex communication systems can handle path delay requires the ability to generate precise and repeatable delay at the physical layer.

Reels of fiber suffice for crude testing, but for more control and precision, test engineers sought an instrumentation approach.

General Photonics provided a system that allowed the customer to use one compact instrument not only to quickly switch between delay values, but to test many more different delays than was possible using stand-alone fiber spools.
