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.

10G DPSK Demodulator
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.

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.

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.

Tunable Edge Filters
Tunable edge filter is a customized product. It usually belongs to 2-port optical tunable filter product platform. Instead of using narrow bandpass filter in the 2-port tunable optical filter, the tunable edge filter utilizes a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tunable edge filters support C-band or L-band wavelength range.

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.

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.
