Coherent Terabit Test & Measurement Instrumentation for Multi-band

At a Glance

  • Fraunhofer HHI offers test & measurement equipment
    for Tbit/s coherent communication systems in the O- and S-C-L-U-Band
  • Ideal for generation, transmission and coherent detection of
    high-speed optical dual-polarization m-PAM and m-QAM signals

Technical Background

  • Multi-band capable coherent terabit communication is the key technology for ultra-high-speed data transmission. Coherent optical transmission techniques allow modulation of amplitude, phase, and polarization of the light for data transport, resulting in unprecedented data rates up to terabits per second.
  • Fraunhofer HHI offers, in cooperation with our partner ID-Photonics, high-performance test & measurement instrumentation with multi-band technology for research and development of the next generation optical fiber-based communication.

The prototype portfolio includes:

  • Transmitter: High-bandwidth dual-polarization transmitter
    up to 60 GHz in S-C-L-Band
  • Transceiver: Compact combined transmitter and receiver
    including laser source for up to 69 GBd
  • Receiver: High-bandwidth polarization-diverse coherent receiver
    up to 100 GHz in O-Band or S-C-L-Band
  • Loop Control: Control & switch unit to emulation
    optical long haul transmission systems from O- to U-Band
