L-Band Single / Dual Stage Isolator

Optical Fiber cable Isolator 1.Operating wavelength (nm)1060 2.Fiber type Corning SMF-28 3.Single and Dual Optical isolatorDescription of optical isolator

Optical isolator is passive devices which can allow light to be transmitted in only one direction. Optical isolator are used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause backscattering and feedback problems. 

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

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.
