Oclaro 40 Gb/s DPSK QPSK LN Optical Fiber MZ Dual Parallel QAM Modulator 792000850

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.

Typical Application

Quadrature modulation (QPSK or 4QAM)

Single side-band suppressed carrier (SSB-SC) transmission
