VI Systems launches driver IC with 63GHz bandwidth for ON-OFF keying

VI Systems offers a new set of ultrahigh-speed multi-rate driver and amplifier chips which target applications in data communications at low latency RZ (return-to-zero) and NRZ (non-return-to-zero optical) modulation at bit data rates up to and beyond 50 Gbit/s and in time-of-flight (ToF) sensing at ultimate spatial resolution. These driver and limiting amplifier integrated circuits are available in the chip form and also being integrated into transmitter and receiver optical assemblies with integrated vertical cavity surface emitting lasers and PIN photodiodes, allowing 50Gb/s “ON-OFF” keying (OOK) data transmission. The chips are suitable for different types of directly modulated micro-lasers and PIN photodetectors having a high modulation bandwidth and can be applied for multi-mode and single mode data transmission, as well as in free space.

The chips match applications such as,  IEEE 802.3bs (400G CWDM8), IEEE Std 802.3-2015, OIF-CEI-03.1 (http://www.oiforum.com), OIF-CEI-56G specification family (http://www.oiforum.com) QSFD-DD MSA (http://www.qsfp-dd.com/) OSFP MSA (http://osfpmsa.org/), ITU-T Recommendations G.652 and G.657 and latest 400G MSA based on coarse wavelength division multiplexing (CWDM) (https://www.cwdm8-msa.org/)
