Product Description

500mW Single Double Stage Polarization Maintaining Fiber Optical Isolator

 

Product Description

An optical isolator is a passive magneto-optic device that only allows light to travel in one direction. Isolators are used to protect a source from back reflections or signals that may occur after the isolator. Back reflections can damage a laser source or cause it to mode hop, amplitude modulate, or frequency shift. In high-power applications, back reflections can cause instabilities and power spikes.Optical isolators are also known as optoisolators, optocouplers and photocouplers.

Features
 

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

Detailed Photos

 

An optical fiber isolator is a passive device that allows light to travel in one direction through an optical fiber, while suppressing light traveling in the opposite direction. This is useful in many applications, such as laser systems, where back reflections can damage the light source or cause other issues. The level of suppression is called the optical isolation, and the higher the isolation, the better the source is protected.
