The PFO SPL500 (Dual Strain Mode) is able to simultaneously measure changes in fiber Elongation and Attenuation at the same time as acquiring other data such as Cable Extension, Mechanical Load, Environmental Temperature and other desired variables.

The PFO SPL500-MW (Multiple Wavelength Testing Mode) option utilizes the systems wavelength programming capability to enable the system to test more than one wavelength at the same time, reducing the need for repeat tests.
