Optoplex Corporation
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.

Hangzhou Huatai Optic Tech. Co., Ltd.
1550nm externally modulated optical transmitter is the core equipment in the RFTV network system.RFTV is a unidirectional analogue and digital video broadcast. It adopts high efficiency modulation mode for RF carrier wave and its economy , flexibility and bandwidth validity is beyond comparison of IPTV. By adopting EPON, GEPON or P2P access mode to realize triple-play and FTTx, RFTV broadcasting network in 1550nm optical wavelength still plays an important role.

M8296A -
Keysight Technologies
The Keysight M8296A is a four-channel, high-speed electrical digitizer module for the AXIe platform. It can synchronously sample up to four incident waveforms and is ideally suited to digitize the output signals from a dual-polarization coherent receiver. Keysight's vector signal analyzer and optical modulation analyzer software serves as the M8296A's user interface and enables a multitude of test and measurement tasks such as spectral analysis and digital demodulation for the analysis of signal quality metrics like error-vector magnitude. Furthermore, the sampled waveform can be stored and processed with the user's own tools (e.g. using Matlab). The modular approach allows users to combine the M8296A high-speed digitizer with other modules in one mainframe such as the M8292A modular optical modulation analyzer and the M8196A 92 GSa/s arbitrary waveform generator.

Applied Image, Inc.
The Sinusoidal Array SINE M-19 is a remarkable new test array that achieves 256 cycles per mm while maintaining a significant modulation. It is designed for testing high resolution optical systems such as microscopes. Because its maximum width is 7.5mm, the SINE M-19 is small enough to fit easily onto a standard microscope slide (the TM-G variation is mounted in glass).

Optoplex Corporation
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.

Optoplex Corporation
Optoplex’s Optical DPSK Demodulator, also known as Delay Line Interferometer (DLI), converts phase modulation to amplitude modulation over the entire C+L band in support of data transmission rates of 2.5,10 or 40 Gb/s. The DPSK demodulator is designed for phase modulated optical communication systemsutilized in commercial, defense and space exploration markets. The device plays a key role in improvingsignal quality and performance to meet the expanding demand for higher data rates and more complextransmission formats within current and next generation systems without major capital expenditure.Optoplex’s DPSK Demodulator is based on a patented free-space optical design, which is compact, athermal and polarization-independent. The measured frequency drift over temperature is only ~0.02 GHz/°C for our standard passive device. Further, this DPSK Demodulator exhibits a total polarization-dependent phase shift of less than 2 degrees over the entire operating temperature range with a high extinction ratio. Optoplex’s DPSK Demodulators can be configured to be fully tunable, colorless tunable or purely passive. Dual-Rate DPSK Demodulator is also available.
