New 3-in-1 Optical Component Analysis delivers OFDR, WDL and Proximity Sensing

Stand 228

29th March 2023

Santec’s SPA-100 has been designed for characterising photonic integrated circuits (PICs), fibre optic components, and compact fibre optic assemblies. Optical frequency domain reflectometry (OFDR) is used to analyse losses as a function of distance with better than 5 μm spatial resolution. Coherent detection allows transmissive wavelength dependent loss (WDL) measurement with a wide 70 dB dynamic range in a single scan. The SPA-100 also has a patented proximity sensing function which measures and automatically adjusts the distance between optical fiber probe and wafer as an aid for alignment.
