Product Description

Single Mode  Super Mini Isolator Apply for Fiber Sensors
Product Description
A mini optical isolator is a small device that allows light to pass through in one direction while blocking it in the other. They are used to prevent unwanted feedback into lasers and to suppress or redirect backscattered light. Mini optical isolators are often used in compact systems because of their small size, which can allow for more lasers and isolators to be integrated.

Features

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

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.
