Product Description

500W 1480nm 1550nm Single Mode Optical Fiber Isolator for Lasers

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 are used in many applications, including:

• Reducing multipath interference

  Optical isolators can help reduce interference in optical communication systems. 

   

   

• Improving system design

  Optical isolators can suppress interactions between devices, undesired light routing, and other spurious interferences. 

• Protecting lasers

  Back reflections can cause lasers to mode hop, shift frequency, or amplitude modulate.
