SPL500
Fiber strain, power and length measurement system that measures fiber elongation and attenuation simultaneously while a cable is under mechanical stress.
Technical overview
The SPL500 monitors fiber length and attenuation during cable mechanical testing, resolving fiber length to sub-millimeter level according to PFO. It also logs associated parameters such as cable extension, mechanical load and environmental temperature, so strain in the fiber can be correlated against the stress applied to the cable. Broad-band SLED sources cover 1250-1650 nm. Configurations range from a single fixed wavelength (typically 1550 nm) through dual wavelength (1310 nm and 1550 nm) to up to four programmable wavelengths measured simultaneously.
