Fujitsu Launches World’s Fastest 1.2Tbps DCO Daughter Card for Multiple Applications

February 27, 2019

Kawasaki, Japan, February 27, 2019 - Fujitsu Optical Components Limited (FOC) announced today that it has released the world’s fastest 1.2Tbps Digital Coherent Optics (DCO) Daughter Card (*1). This card enables up to 1.2Tbps coherent transmission for multiple applications such as ZR, Metro, Long Haul, Data Center Interconnect (DCI) and Submarine.

By adding the 1.2Tbps DCO Daughter Card to FOC’s broad portfolio of high bandwidth products such as 64Gbaud LN modulator (*2) and 64Gbaud integrated coherent receiver (ICR) (*3), which have already been commercialized, FOC can address customers’ various requirements for both modules and devices.

FOC has released the world’s fastest 1.2Tbps DCO Daughter Card, which enables up to 1.2Tbps coherent transmission. The card can support multiple applications such as ZR, Metro, Long Haul, DCI and Submarine so as to meet the capacity needs and efficient system upgrades of global network service providers and datacenter operators.

Product Feature

  • This product supports various baud rates and modulation formats from 32Gbaud QPSK to 64Gbaud 64QAM by combining multiple baud rates and modulation formats including hybrid-coding and/or multi-dimensional modulation format, targeted to support multiple applications for long haul (thousands of kilometers), metro (hundreds of kilometers) and 80 to 120km ZR transmission.
  • Using 64Gbaud coherent DSP (Digital Signal Processor), in-house 64Gbaud LN modulator and in-house 64Gbaud ICR, this product enables coherent transmission of up to 1.2Tbps, which is six times the transmission speed of existing 200Gbps DCO transceivers.
  • Using in-house L-band LN modulator, this product is able to support L-band transmission in addition to the C-band from the beginning of commercialization, thus enabling very large capacity coherent transmission in the C + L bands (Maximum wavelength number of 190).
