 Polarization Maintaining (PM) Fiber-Optic Circulator (PMFC)

 

Description:

 

The three port in-line polarization maintaining (PM) fiber optic circulator routes PM optical signals in a unidirectional sequential order from port 1 to 2 and port 2 to 3 while maintaining the polarization with high extinction ratio. It features low insertion loss, high isolation, high extinction ratio, high return loss and high stability and reliability. The PM circulator is package in a small size reliable in-line package compatible with all demanding applications.

 

  

 

Applications:

 

·        Bi-directional transmission systems

·        WDM & DWDM transmission systems

·        Add/drop multiplexers

·        Fiber optic amplifiers

·        CATV networks

·        Optical test instrumentation

 

 

Key Features:

 

·        Low loss

·        High extinction ratio

·        High isolation

·        High return loss

·        Compact in-line package.
