Magneto Optical Switch Single Stage 1X2
Description
Magneto fiber optic switch has been widely researched due to its capabilities handling large beam cross sections, operating at low voltages, featured as low insertion loss and intrinsic non-reciprocity.
A magneto optic switch, comprising: a plurality of optical components positioned in order along a light path comprising: a single fiber optical collimator, a first birefringent optic crystal, a first half wave plate assembly, a polarization rotation assembly, a second half wave plate assembly, a second birefringent optic crystal, and a dual fiber optic collimator.
Features
♦ High switching speed
♦ Better durability
♦ High reliability
♦ Low voltage drive
♦ Fail-safe latching
Applications
♦ Optical channel blocking
♦ Configurable Add/Drop
♦ System monitoring,Test&measurement
♦ Fiber-optics sensing system
