Product description
1x2 or 2x1 optical switch is a kind of solid state light switch, the internal no moving components, is based on Faraday effect. This series of products use the principle of electromagnetic induction and Faraday optical rotation effect to change the polarization state of the incident beam, combined with the use of birefringent polarization splitting crystal, so as to change the beam propagation path, so as to achieve the function of optical path switching.
Feature
Non-moving component
Fast switching speed
Extremely stable latch mode
Low power consumption
Excellent stability and reliability
Application
High speed protection
System monitoring
Test and measurement
