40G IQ/QAM Lithium niobate modulator Modulator Oclaro Oclaro 792000850
This optical modulator is dual arm RF drive,suitable for modulation format DQPSK;Maher Zed modulator,partial input and output,maximum rate of up to 40Gbps;low voltage drive;C+L band work, high extinction ratio. The Oclaro DQPSK(Differential Quadrature Reference Phase Shift Keying) modulator design is based on a dual parallel structure of two Mach-Zehnder modulators embedded in a Mach-Zehnder super-structure. Each internal modulator is designed to support 22 Gb/s signals. An integrated polarizer enables high extinction ratios as required for the DQPSK modulation format. High bandwidth photodiode is provided for automatic bias control.
