Elementary Fiber Optics Trainer
Product Code : JA-AET-1477
The elementary fiber optics trainer is a simplex analog and digital fiber optic link working at 660 nm, with AM, FM and PWM modulation and demodulation, an on-board function generator and a voice link. Students set up analog and digital links, measure propagation loss, bending loss and numerical aperture, and trace switched faults, using the supplied PMMA plastic fiber cables, NA jig and mandrel (SKU JA-AET-1477).
