40Gb/s Coherent Receiver
The integrated 40-Gb/s DP-QPSK receiver incorporates two 90° optical hybrids with four pairs of balanced photodetector (PD) and four linear TIAs into a single butterfly package. Unlike other technologies in which the polarization beam splitter (PBS) and/or the power splitter (BS) are not included, Optoplex’s receiver includes both of them with the optical hybrids, PDs and the TIAs to offer a fully integrated solution which will benefit users in terms of completely removing fiber routing and the skew management. The integrated receivers work at the symbol rate up to 12.8GBaud/s.

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.

3-Port ROADM / TOADM
Optoplex's Reconfigurable Optical Add/Drop Multiplexer (ROADM) module, also known as Tunable Optical Add/Drop Multiplexer (TOADM), is based on a proprietary micro-optics and micro-actuator design, athermal packaging technology, and state-of-the-art thin-film coating. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), this 3-port ROADM device directs a selected channel to the Drop-Port (ADD/DROP) and the remaining channels to the Express-Port (EXP), as depicted in the figure below. This tunable feature can also be used for adding a channel, when the device is used in reverse. Cascading two ROADM modules, simultaneous add and drop functions can be achieved. Each single ROADM device is optimized to cover either C- or L-band wavelengths. The standard 100- or 200-GHz channel spacing ROADM products allow for single-channel drop. Customized banded-channel drop ROADMs are available upon request.

Optical Performance Monitor
Optoplex Optical performance monitor (OPM) uses proprietary thin-film interference filter technology combined with a micro-actuator and high-speed electronics. Optical performance monitor is used to measure critical information data on optical transmission signals in DWDM networks for monitoring signal dynamics, determining system functionality, identifying performance change, and providing feedback for controlling network elements so as to optimize operational performance. In particular, Optoplex Optical performance monitor can automatically scan the C-, L- or C+L-band wavelength range and precisely measure channel wavelength and power. See the following schematic diagram for OPM working principle.

2x8 QPSK Mixer
To be used for optical coherent detection such as DP-QPSK receivers, Optoplex’s ten-port 2x8 Coherent Mixer (aka QPSK mixer) combines the incoming signal with a local oscillator to generate eight light states in the complex-field space. The eight light output signals can then be coupled into four pairs of balanced detectors. The block diagram below shows the application of a 2x8 coherent mixer in a DP-QPSK receiver. Since the mixing process is data rate independent, the devices can be used for any data rate in applications such as 40Gb/s or 100Gb/s transmission systems.

Optical Wavelength Meter
Optoplex Optical wavelength meter (OWM) uses proprietary thin-film interference filter in conjunction with Fabry-Perot cavity technology combined with a micro-actuator and high-speed electronics. Its working principle is schematically shown below. By comparison with Optical channel monitor / Optical performance monitor, the proprietary wavelength reference unit is introduced to ensure high precision wavelength measurements. Optoplex Optical wavelength meter is the only DWDM wavelength meter capable of measuring wavelengths of multi-lasers in DWDM networks over C-band and L-band wavelength range with a high accuracy better than that the wavelength locker can provide. For example, the device can simultaneously report 80 wavelength values of 80 channels at 50 GHz channel spacing with the wavelength accuracy ± 2 GHz. DPRAM, RS-232, or USB interfaces are available and OWM can be customized to meet specific requirements.

90-Degree Optical Hybrid
Six-port hybrid devices have been used for microwave and millimeter-wave detection systems since the mid-1990s and are a key component for coherent receivers. In principle, the six-port device consists of linear dividers and combiners interconnected in such a way that four different vectorial additions of a reference signal (LO) and the signal to be detected are obtained. The levels of the four output signals are detected by balanced receivers. By applying suitable baseband signal processing algorithms, the amplitude and phase of the unknown signal can be determined.
