NK420 fibre-optic identifier
The fibre-optic identifiers perform no-loss tests of the circuits using macro-curving techniques, which identify light signals, power and direction without interruption, and are used to locate, install and wire specific fibres or separate them.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
