40G IQ/QAM 铌酸锂調制器 Modulator Oclaro 奧蘭若 792000850
Description
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.

Application
  • Quadrature modulation (QPSK or 4QAM)
  • Single side-band suppressed carrier (SSB-SC) transmission
