The working of this is like when light passes through the i/p polarizer in the forward direction & turn into polarized within the vertical plane. The block diagram representation is shown below. KyUElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product Working PrincipleĪn optical isolator includes three main components namely a Faraday rotator, i/p polarizer, & an o/p polarizer. The working of this component mainly depends on the Faraday’s effect which is used in the main component like Faraday rotor. So it plays a main role while preventing unnecessary feedback to an optical oscillator namely laser cavity. It is a passive magneto-optic device, and the main function of this optical component is to permit light transmission in one direction only.

To overcome the interference effects, an optical diode or optical-isolator is used. These effects may cause light energy to be reproduced back at the supply and obstruct with supply function. So, these effects may cause light energy. The optical devices as well as connectors in a fiber optic system cause some effects like absorption, and reflection of the optical signal on the o/p of the transmitter. KyUElectronic Parts,Electronic Components distributor,memory,flash, integrated circuit,Original Product The direction of rotation mainly depends on the magnetic field as an alternative of the light transmission direction. This effect refers to a fact that the polarized light plane turns when the light energy transmits through the glass that can be exposed toward a magnetic field. In the year 1842, Michael Faraday was stated that the optical isolator operation depends on the Faraday Effect.
