COMMUNICATIONS COMPONENTS
2x2 High Speed Lithium Niobate Interferometric Switch
Key Features
* High polarization extinction * Low drive voltage * Low fiber-to-fiber insertion loss * 1550 nm operation
Applications
* Nanosecond switching
The JDSU 2x2 Interferometric Switch is a high extinction, high speed switch. Because the waveguides are polarizing, control of the input light polarization is required. Switching speeds in excess of 1 ns are attainable. Input and output fibers are polarization maintaining.
