ID Photonics enhances IQ Multi-Format Transmitter to 40GHz Bandwidth supporting 64GBaud Applications
Neubiberg, Germany – ID Photonics, a leading test and measurement provider for coherent transmission system solutions, enhances its IQ Multi-Format Transmitter RF bandwidth to more than 40GHz.
The IQ Multi-Format Transmitter is a fully integrated laboratory optical transmitter enabling researchers to generate coherent modulated signals at symbol rate up to 64GBaud. The integration of transmitter calibration data into Keysights M819 AWG portfolio yields unparalleled system performance enabling the generation of 64Gbaud multi-level constellations.
The unit features our proven pattern independent Automatic Bias Control (ABC) that achieves optimal performance irrespective of modulation formats enabled by our unique zero noise feature. Researchers can seamlessly change modulation formats and symbol rates without any concerns for maintaining the modulators bias stability supporting automated impairment and stress testing for reduced product development cycles.
"ID Photonics is dedicated to providing the highest performance test instrumentation to our customers for the development of next generation transmission systems. The significant bandwidth enhancement of our Multi-Format transmitter allows researchers to unleash the full potential of latest Arbitrary Waveform Generator (AWG) instruments available. High Fidelity Constellations at up to 64GBaud can only be achieved if proper matching of both electrical signal source and E/O converter is achieved. By providing calibration files that can be seamlessly integrated into Keysights latest AWG product line, we have the unique capability to generate these high fidelity signals." said David Stahl, General Manager of ID Photonics.
The IQ Multi-Format Transmitter is commercially available immediately. It is available in multiple configurations, including full-dual polarization, emulated dual polarization and single polarization.
The unit will be on display from March 22 to 24th at the OFC 2016 exhibition in Anaheim, booth #3102. A live demonstration using a Keysight AWG signal source is held at booth #2901.
ID Photonics introduces automated BIAS Control for IQ-Mach Zehnder structures optimized for flexible Multi – Level modulation formats
Neubiberg, Germany – ID Photonics, a leading test and measurement provider for coherent transmission system solutions, extends its portfolio by a new type of automatic BIAS control for complex multi-level signals such as QAM-16 jointly developed with Fraunhofer Heinrich-Hertz-Institute. Unlike other solutions on the market, it is independent of the applied RF signal (constellation), requires no manual tuning by a user for optimal results and features a zero noise mode for reference measurements. The solution is available in a turnkey ready fully integrated high-end E/O converter instrument that connects to Arbitrary Waveform Generators (AWG). Additionally, a standalone board provides a solution for customers aiming to build a customized RF chain and Mach Zehnder Modulator device but require a best-in-class automatic BIAS control feature.
"The industry is currently advancing from standard 100G DP-QPSK technology to modulation formats such as QAM-16 that require multi-level coding. This step opens the possibility to flexibly implement a large variety of potential formats and flavors which all need to be evaluated and selected for network and system designs. A test solution that generates a multitude of optical transmitter signals in a stable and format independent way is required to help researchers and developers addressing this challenge. While Arbitrary Waveform Generator (AWG) instruments are readily available to generate the electrical drive signals, E/O converters suffer from inherent drift of the optimal operating point versus time that needs to be compensated for. This task is performed by automated BIAS control circuits utilizing control feedback signals generated in the E/O converter. For IQ modulators used in advanced systems, previously available solutions tap RF components present from the modulated data signal as a feedback signal source. Naturally, this causes a strong dependency on modulation format and test data pattern applied. Thus, instability of the control is a big issue and manual tweaking for each case is required. Our new automated BIAS Control eliminates all these issues by an inherently RF signal independent design providing a best-in-class minimal penalty automated BIAS control." said David Stahl, General Manager of ID Photonics.
ID Photonics extends its popular CoBrite Tunable Laser Portfolio by ultra-narrow line width tunable laser source
Neubiberg, Germany – ID Photonics, a leading test and measurement provider for coherent tunable laser solutions, extends its laser portfolio with a new ultra narrow line width tunable laser source jointly developed with Teraxion. The new laser source provides a line width of less than 1 kHz and is targeted for next generation coherent R&D applications beyond 100 Gbit/s. It is launched at OFC2014 and will be available for the popular CoBrite multi-channel laser platform. It can be mixed with all already available sources and chassis variants providing ultimate flexibility for testing current and next generation transmission formats.
"Future transmission speeds are enabled by increasing constellation size and baud rate which impose even more stringent requirements for narrow line width light sources when compared to current 100Gbit/s DP-QPSK technology. Our new laser source supports researchers and system designers in the evaluation and the design of next generation networks with the best-in-class tunable narrow line width laser for multi-channel operation currently available. It makes the CoBrite laser platform a future proof investment for the evaluation of future ultra-high-capacity network architectures" said David Stahl, CEO of ID Photonics.
The new ultra narrow line width laser will be on display from March 11 to 13th at the OFC 2014 exhibition in San Francisco, booth #3556.
