1x2 PM Magnet Optic Switch

This product is an optical device based on the Faraday magneto-optical effect, which can switch a Polarization-Maintaining (PM) optical fibre input signal all the way to any one of the 2 polarisation-maintaining output ports, while keeping the polarisation state of the input light unchanged. Core features: 1 x 2 optical switching, Polarisation-Maintaining (PM), non-mechanical switching.

 Product description

The 1x2 or 2x1 optical switch is a solid-state optical switch that does not have any moving components inside and is based on the Faraday effect. This series of products use the principle of electromagnetic induction and Faraday rotation effect to change the polarization state of the incident beam, combined with the use of birefringent polarization beam splitter crystal, so that the beam propagation path is changed, thus realizing the functio
