Product Description

High Return Loss 1550nm Single Mode Fiber Optical Isolator

Product Description

An optical isolator is a device that allows light to pass through in one direction but not the other. They are used to protect light sources from back reflections and other signals that can damage or destabilize them. 

Features

• Low Insertion Loss
• High Return Loss
• High Stability & Reliability
• High lsolation

Applications

• Test Instrument
• Fiber Optical Laser
• MOPA Fiber Optical Laser
• PM Optical Fiber Amplifier

Our Advantages

Optical isolators work by using the Faraday Effect, which states that the plane of polarized light rotates when it passes through a material exposed to a magnetic field. The direction of the rotation is determined by the direction of the magnetic field, not the direction of the light. This non-reciprocal rotation allows the isolator to block light in one direction while allowing it to pass in the other.
