How to Leverage 400G ZR+ for Optical Network Innovation

Recorded on: 21 February 2024


Join us for an in-depth webinar where we unravel 400G ZR+ technology and discuss its transformative impact on data center interconnects. Our panel of experts from Edgecore Networks, Coherent, and IP Infusion will guide you through the nuances of leveraging this advanced optical solution to fuel network innovation and stay ahead in a competitive landscape.

What you Will Learn:

  • The impact of 400G ZR+ technology on traditional network architecture
  • Key design considerations for integrating high-power 400G optics into existing data center infrastructure.
  • The role of next-generation network operating systems in managing 400G environments.
  • The economic and operational benefits of direct pluggable optics compared to traditional transponder-based architectures.
  • Real-world case studies demonstrating the operational advantages of 400G solutions.


The qualification of transceivers is a multifaceted and resource-intensive undertaking. Together with our valued partners Edgecore and IP Infusion, we have done the qual for you.

Customers adopting 400G coherent transceivers on Edgecore switches and routers can be assured of functionality, efficiency and performance - the switch has been designed to protect the expensive optics. The hardware is powered by IP Infusion's OcNOS which since the 6.4 release has been developed to ensure plug-and-play integration with the 400G ZR+ transceivers.

Why 400G ZR+?

600km reach ZR+

400G ZR+ builds upon the 400G ZR standard by enabling transmissions over longer distances, potentially up to several hundred kilometers, without the need for inline optical amplification, such as Open WDM line systems.

This is particularly useful for service providers and enterprises looking to interconnect data centers that are geographically dispersed but not so far apart as to require a full-fledged long-haul optical transmission system, and offers massive CapEx savings.
The "+" in 400G ZR+ typically indicates enhancements such as:

  1. Increased reach: Potentially up to 400-1000 km, depending on the implementation and fiber conditions.
  2. Higher performance: Signal integrity can be maintained over longer distances.
  3. Flexibility: Adjustable power and performance parameters to optimize for specific network scenarios.

What sets Coherent's 400G ZR+ optics apart from competing solutions is that they operate at 0dBm transmit power, the optics are programmable to suit a wide range of networks and applications, there's a choice of line rates and choice of form factors CFP2 and QSFP-DD.

Next-Gen DCI: Mastering 400G ZR+ for Ultra-High-Capacity Networks

Podcast - Part 1

In Part 1, we delve into the transformative impact that 400G ZR+ technology is having on data center networking. The introduction of advanced 400G ZR+ optics eliminates layers of complexity in DCI, removing the need for separate transponder layers, and promises longer data transmission distances, enhanced efficiencies, sustainability and performance.


Podcast - Part 2

In Part 2 of the podcast we explore the software side of implementing 400G technology in data centers including how to manage and tune 400G transceivers. Our industry experts outline the qualification processes these high-performance components have undergone to build an interoperable plug-and-play 400G ZR+ solution, as well as the anticipated advancements in network management through AI and machine learning.
