2x2 PM Magneto-Optic Switch

The 2×2 bias-preserving magneto-optical switch is an optical device based on the magneto-optical effect (e.g. Faraday effect) that enables fast switching of the optical path between two bias-preserving (PM) fibre optic ports while maintaining the polarisation state of the input light (e.g. linearly polarised light).

Product Description

2x2 optical switch is an all solid-state device without any moving parts. The switching of the optical light is realized by utilizing Faraday Effect.This is achieved using a patent protected non-mechanical configuration with solid-state all-crystal design which eliminates the need for mechanical movement. The microsecond fiberopticswitch is designed to meet the most demanding switching requirements ofreliability, durability, response, and continuous high frequency switching.

Features

No moving parts, best durability

Ultra fast switching speed

Extremely stable latching mode

Easy to route -all fibers on same side

Exceptional reliability and stability

Applications

Optical switching

High speed protection

System monitoring

Test & measurement

Fiber-optics sensing system
