High Power optical fiber cable Isolator

Optical Fiber cable Isolator 1.Operating wavelength (nm)1310 2.Fiber type Corning SMF-28 3.Single and Dual stage 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.

Fiber Isolator application

 

Fiber isolators are used in many fiber optic applications in corporate, industrial, and laboratory settings.  They are reliable devices when used in conjunction with fiber optic amplifiers, fiber optic ring lasers, fiber optic links in CATV applications, and high-speed and coherent fiber optic communication systems.  Single polarization fiber optic isolators are also used with laser diodes, gyroscopic systems, fiber optic modular interfaces, and a variety of other mechanical control and testing applications
