DQPSK Demodulator

EZconn's GT40-9002DM and GT40-9003DM is the smallest in the word second generation DQPSK demodulator.

It is available in two different packages for better fit in to the customer design. It is based on eGtran´s patent-pending micro optics design. It includes a 50:50 beam splitter and two identical Mach-Zehnder interferometers. Fast tuning is implemented with hughly integrated actuation circuits. For inline optical power monitoring, a photodiode is implemented in the module.

Available free spectral range (FSR) of the demodulator includes 21.5, 21.9, 22.5, and 25GHz. Other custom FSRs can be provided upon request.
