The SPL500 is a fiber strain measurement system that measures fiber elongation and attenuation simultaneously during mechanical stressing of the cable. The SPL500 is designed to produce accurate measurements quickly and with confidence.

The SPL500 also acquires other valuable information such as cable extension, mechanical load, environmental temperature, and other similar parameters. This enables accurate monitoring of the physical stresses on fiber and fiber cables during installation and operation, which otherwise leads to operational failure.

Features & Benefits
