COMMUNICATIONS COMPONENTS
Key Features High polarization extinction
Low drive voltage
Low fiber-to-fiber insertion loss
1550 nm operation
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.
Applications
