Modular Multi-Terabit Turn-Key Solution for Testing your Elastic Optical Network Designs
Bandwidth explosion requires pushing the envelope of next generation transmission systems to new capacity limits using high-order complex modulation formats, such as 16-QAM and flexible channel grid systems to allow for closer channel spacing and ultimately higher system capacity.
ID Photonics and Fraunhofer Heinrich Hertz Institute jointly developed a modular test solution that provides researchers and engineers a comprehensive way to design and test future ultra-high capacity network architectures up to 54 Tb/s for the coherent transmission era using various modulation formats and channel configurations with unsurpassed ease of operation.
This joint development consists of an optical multi-format transmitter that enables a flexible generation of optical data signals with various modulation formats (PSK, QPSK, 16-QAM, etc.) for up to 272 Gb/s per carrier when using 16-QAM. Each multi-format transmitter includes four intuitively programmable 34-GS/s (giga-samples per second) arbitrary waveform generators (AWG), electrical driver amplifiers and a high-bandwidth dual polarization IQ-modulator as well as a nonlinear pre-distortion processing unit to compensate for impairments caused by the high-speed electrical-to-optical signal conversion. Its unique capability to synchronize all four AWGs allows generating realistic transmission scenarios required for future network designs.
ID Photonics versatile carrier comb generator provides up to 200 DWDM channels and consists of narrow line-width tunable lasers optimized for coherent transmission. On that basis, the platform allows for generation of multi-Terabit/s test signals (up to 54 Tb/s when fully equipped) using different modulation formats, carrier spacings and wavelength bands in a very flexible way by just a few mouse clicks. The modular design of pluggable tunable laser units with an industry-leading portfolio of chassis variants adapts to customers’ needs and easily allows extension of existing installations.
The platform comes with an intuitive graphical user interface (GUI) and a digital signal processing (DSP) library for generation of arbitrary waveforms. This enables tailored adaptation to customer specific implementations and data formats.
