VENDOR : optilab


The Optilab QPSK-OM-23 Quadrature Phase Shift Keying (QPSK) modulator is a dual parallel structure of two Mach-Zehnder modulators embedded in a MachZehnder super-structure. It is also often knowns as an IQ modulator or nested modulator. Each internal modulator is designed to support 23 Gb/s signals. An integrated polarizer enables high extinction ratios as required for the QPSK modulation format. Contact Optilab for more information.
