40Gb/s DQPSK Receiver
-
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

40Gb/s DPSK Receivers
-
Targeting for the next-generation 40Gb/s system based on advanced optical differential phase shift keying (DPSK) demodulation, Optoplex’s 40Gb/s Integrated DPSK Receiver (DPSK Rx) demodulates an incoming DPSK optical signal into a pair of differentially (amplitude) modulated RF outputs at data rate up to 43Gb/s in a compact package. Phase modulated optical signals offer much better dispersion performance compared with traditional amplitude modulated counterparts because the carrier light stays on all the time so that the intensity-dependent nonlinear effects in the transmission link are avoided, resulting in longer transmission distances.

General Purpose Basic Carrier Demodulator
CD15
-
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.

DPSK Demodulator
-
Optical differential-phase shift keying (DPSK) provides a desired modulation format that offers high receiver sensitivity, high tolerance to major nonlinear effects in high-speed transmissions, and high tolerance to coherent crosstalk. In DPSK, data information is carried by the optical phase difference between adjacent bits. For direct detection of DPSK signal (by conventional intensity detectors), a DPSK demodulator is needed to convert the phase-coded signal into an intensity-coded signal.

DQPSK Demodulator
-
Differential Quaternary Phase-Shift Keying (DQPSK) is the four-level version of DPSK. DQPSK transmits two bits for every symbol (bit combinations being 00, 01, 11 and 10) and has an additional advantage over conventional binary DPSK. DQPSK has a narrower optical spectrum, which tolerates more dispersion (both chromatic and polarization-mode), allows for stronger optical filtering, and enables closer channel spacing. As a result, DQPSK is the only modulation format which allows processing of 40Gb/s data-rate in a 50-GHz channel spacing system.
