Optical circulator

Optical circulator
Mini Circulator
Optical circulator is a special kind of fiber optic components, with single fiber bidirectional transmission function. This function is often combined with optical fiber grating and other reflection components used in DWDM system. Dual-way communication system, the dispersion compensation, EDFA application and OTDR measurement.

Feature ：                                            
•High Channel Isolation                            
•Low Insertion Loss                                 
•High Return Loss                                  
•Low PDL                                              
•High Stability and Reliability                     
                                                               
Application ： 
•Optical Fiber Amplifier
•CATV Optical Fiber Link
•Optical Fiber System testing
•Wavelength Add/Drop
•Dispersion Compensation
•Bi-Direction Communication
