C+L Band WDM Fiber Optic Circulator Polarization Insensitive Components
C+L Band WDM Fiber Optic Circulator Polarization Insensitive Components
General
An optical circulator is a special optical passive component apply in optical device
it can be used to separate optical powers that transfer in opposite directions.
by in one single optical fiber, analogous to the operation of an electronic circulator.
An standard optical circulator is a three-port device that allows light to travel in only one direction
Example - from port 1 to port 2, then from port 2 to port 3.
This feature is very important to optical bidirectional transmission and communication.
Usually, it is used for optical transceiver, FBG( fiber Bragg grating) filter and optical amplifier.
Features:
- Low Back Reflection
- High Extinction Ratio
- Low Insertion Loss & High Return Loss
Application
- DWDM system
- Add-Drop Multiplexing
- Fiber AmplifierFiber Sensor
- Chromatic Dispersion Compensation Devices
- Fiber Bragg Grating
