FIBERSTAMP Launches Economical DCI BOX and 400G QSFP DD ZR+ Coherent Optics for Open Optical Networks

Singapore, May 17th, 2023 – Boosting the huge demand for long-haul data center interconnection due to the market trend of cloud migration and large-scale integration of digital services, FIBERSTAMP introduces the new 400G QSFP DD ZR+ coherent optical module, which adopts the latest OpenZR+ specification and standard to improve the compatibility and economic efficiency of long-haul metro interconnect devices. It is also introduce in economical metro coherent 1U DCI BOX and 2U 3.2T DCI BOX to combine more perfect long-haul coherent interconnects solutions.

Up to now, the mainstream view and practice in the industry are to develop OpenZR+ specifications and standards. Highly versatile coherent DWDM optical devices can be provided through a feature combination of devices in the same form factor.

Combination of 400ZR and OpenROADM standard

The FIBERSTAMP 400G QSFP-DD ZR+ adopts the latest OpenZR+ specifications and standards, enabling the product to be compatible with commonly used optical module form factors. With its excellent compatibility and scalability, it can transmit beyond 450km.


  • Transmission distance up to 400km
  • Advanced process 7nm DSP
  • RX OSNR tolerance meets 24dB/0.1nm
  • Operate at full C-band DWDM wavelengths at 75GHz (up to 64 channels) or 100GHz (up to 48 channels) channel spacing
  • Triple-temperature power consumption < 22W

The combination of 400G OpenZR+ and high-density routing platform provides a more stable and efficient solution for data center interconnection. Therefore, it is also very important to optimize the integration of DWDM and routing, which can improve network transmission efficiency and reduce data center operating costs. FIBERSTAMP compact DCI BOX coherent transmission subsystem is a service platform specially designed for data center interconnects and metro network wavelength division multiplexing applications. Meet various needs and provide high-speed and large-capacity solutions for DCI.
