980nm Polarization Maintaining fiber isolator
Product description:
Optical isolator is a passive magneto-optic device that only allows light to propagate in one direction. The optical isolator is used to prevent the light source from being affected by the back reflection or signal behind the isolator. Backward reflection may damage the laser source or cause mode hopping, amplitude fluctuation or frequency shift of the laser source. In high power applications, back reflection can also cause instability and power spikes.
Product features:
- low insertion loss, high isolation
- excellent environmental stability and reliability
- high power handling, high return loss
Product application：
- Optical Fiber Amplifier
- Pump Laser Source
- Fiber Optic Sensor
- Instrumentation

The length of the input and output optical fibers at both ends of the isolator is about 0.8 meters, and the isolator is marked with an arrow pointing to the light transmission direction. Each isolator produced by our company has been strictly tested before shipment to ensure that it conforms to the specifications marked by us. We will provide a complete test report for each product.
