| 1550nm PM Fiber Optic Isolator | |||||||||||||
|
1550nm Polarization Maintaining (PM) Optical Isolator is a fiber passive component built with PM fiber, it allows light signal to be deliveried in one forward direction and avoid the back reflection light, it's widely used in amplifier system, fiber optic sensor system to protect the light source and lower down the optical signal noise. |
