LiFi System for robust vehicle to vehicle communication

The new optical wireless communication system from Fraunhofer HHI is optimized for an extremely large coverage. Thereby it can realize high speed data communication in an significantly extended area and allows for a high degree of mobility. The light-based LiFi system can be used in harsh industrial environments and is especially well suited for vehicle to vehicle communication. Due to the large coverage angle of more than 120°, vehicles can communicate with a stable connection at high speeds while moving. Using light-based instead of commonly used radio-based systems enables a robust hacking-, jamming-, and interference-free transmission.

Coherent Receiver Frontend

Fraunhofer offers a fully integrated 100 GHz bandwidth coherent receiver frontend with optical extender heads

To cope with the continuously growing demand for bandwidth over multiple wavelength bands in telecom and datacom applications, Fraunhofer HHI researchers developed a Coherent Receiver Frontend (CRF), offering 100 GHz bandwidth detection with polarization- and phase-diversity over S+C+L-band. Its unique features are optical extender heads with robust 1mm RF ruggedized connectors enabling high signal integrity, robust testing & measurement performance and convenient handling & operation for our customers.

400G Coherent Optical Frontend

Fraunhofer presents a compact 400G I/Q transmitter and coherent receiver for high-bitrate transmission experiments

The 400G Coherent Optical Frontend is a compact optical transceiver to demonstrate high-bitrate data transmission. The transceiver allows for flexible generation and detection of optical data signals up to 64 GBaud. This corresponds to 400 Gbit/s using PDM-16QAM modulation. Several transceivers can be combined in one chassis to realize a multi-channel system, e.g. for space-division multiplexing.

Integrated Coherent Optical Receiver

Fraunhofer HHI and ID Photonics offer a fully integrated Coherent Optical Reference Receiver with up to 60 GHz

The latest test & measurement equipment launched by Fraunhofer HHI and ID Photonics is the fully integrated Coherent Optical Reference Receiver. It comprises a high-bandwidth coherent receiver with transimpedance amplifiers to convert optical data signals with various modulation formats (e.g. QPSK and m-QAM) into electrical RF baseband signals with an o/e bandwidth up to 60 GHz. Its unique features are a high fidelity tuneable C-band laser source and a fully integrated Coherent Optical Receiver, allowing operation at symbol rates beyond 120 GBaud, enabling transmission capacities in the Terabit/s single carrier regime.

Integrated DP-IQ Reference-Transmitter

Fraunhofer HHI and ID Photonics offer a fully integrated High-Bandwidth DP-IQ Reference Transmitter

Fraunhofer HHI and ID Photonics are presenting at this years OFC the DP-IQ Reference Transmitter. It is a fully integrated optical frontend instrument that converts differential electrical RF signals into various optical modulation formats (e.g. QPSK and m-QAM) using a high fidelity tuneable laser source followed by a high-bandwidth dual-polarization IQ Mach Zehnder modulator with a flexible and highly stable automatic bias control. It is an ideal match to convert signals generated by an Arbitrary Waveform Generator (AWG) into the optical domain.
