Coherent Optical Transport
Optical fiber communication networks provide the required capacity and reliability for today's high-bandwidth internet applications and services. Coherent optical techniques allow to modulate amplitude, phase and polarization of the light for data transport resulting in unprecedented per-channel data rates spectral efficiency, flexibility and robustness, coherent optical transport is a widespread technique for longhaul transmission. Currently, it is also migrating to data center interconnect, access and short reach scenarios.
Rapid real-time prototyping
Digital signal processing (DSP) has become an ubiquitous toll in coherent communication systems, vastly increasing data rates, flexibility and robustness. Real-time DSP processing of tens and hundreds of Gb/s per channel needs large application-specific integrated circuits which are extremely costly and time-consuming to develop. Rapid real-time prototyping using a flexible, reprogammable DSP hardware based on field-programmable gate arrays (FPGAs) speeds up development cycles and saves cost while offering all advantages of a real-time implementation.
Fraunhofer HHI offers a highly flexible hardware platform for rapid real-time prototyping of new transceiver concepts for the Tb/s regime.
Innovating coherent communication systems towards Tb/s per-channel capacity requires sophisticated know-how on component, system and network level. Precise characterization, careful optimization and accurate performance evaluation in a system laboratory with cutting edge equipment saves time and cost when working with a partner taht has rich experience and dedication to excellence.
Fraunhofer HHI provides test & measurement services for high-speed coherent communication systems with experienced staff in a world-class system lab environment.
