Fiber Optical Isolator Polarization Insensitive Isolator 1310/1480/1550nm
The Gapho optical Isolator utilizes Faraday effect of Magneto optical crystal. It guides optical light in one direction and eliminates back reflection and back scattering in the reverse direction at any polarization sate. The unique manufacturing process and optical path epoxy-free design enhance the device's high power handling capability.
◇Features:
Low Insertion Loss
High Return Loss, High Extinction Ratio
High Reliability, High Stability
◇ Application:
EDFA & Raman Amplifier
Fiber Sensor, Fiber Optical Instrument
Testing instruments
