Optical Isolator

Product ID: Optical Isolator

Inquiry
The optical isolators are passive optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause backscattering and feedback problems. Optical feedback degrades signal-to-noise ratio and consequently bit-error rate. Ideally a optical isolator would pass all light in one direction and block all light in the reverse direction.

There are two major classifications of optical isolators: In-line optical isolators and free space optical isolators.

Inline optical isolator

Inline optical isolators are designed in pigtail fashion. That is to say that they come with built-in fiber optic cable and connectors so that they may be integrated directly into a fiber optic system. 

Free space optical isolator

Free space optical isolators, by contrast, do not have an integral connection system. They must be directly mounted to the object that needs isolation.  
 
Pigtailed Optical Isolator

Pigtailed Optical Isolator includes an isolator in Ferrule, making it easier to assemble at LD packing.
