The recent announcement from ZTE and MASORANGE feels like a real leap in global telecom tech. In Madrid, on February 27, 2025, the two companies unveiled the world’s first commercial deployment of 800G coherent optical modules integrated with SRv6 in an IP backbone network.
This upgrade could totally change how high-capacity networks handle speed, scale, resilience, and security. It’s setting a new bar for the internet’s backbone—maybe even a whole new playbook for the future.
A Game-Changing Step in Network Evolution
ZTE and MASORANGE teamed up to blend the latest in optical transport with the efficiency of SRv6 (Segment Routing over IPv6). They’re running this on ZTE’s ZXR10 M6000-SE routers, which support up to 256 ports of 800G.
That’s a first for commercial networks. With this much capacity, you get ultra-high-speed data and flexible setups that make infrastructure less of a headache.
Breaking the Speed and Capacity Barrier
The 800G optical modules let network operators hit congestion-free connectivity and ultra-low latencies. It’s not just about going faster—it’s a rethink of how core networks move data.
This boost directly tackles the bandwidth explosion from 5G, soon 6G, IoT, AI workloads, and the sprawling cloud. These demands just keep piling up.
Optimizing Network Infrastructure
One of the standout features here is how the tech splits the optical and IP layers. That lets operators fine-tune resources and scale up without tearing everything apart.
Adjustable wavelength modules also help, trimming down both the physical mess and day-to-day operational hassle.
Reduced Costs and Energy Savings
ZTE claims the new 800G modules slash energy use and costs by simplifying the setup and cutting power draw by up to 80%. That’s a big deal for sustainability, not just performance.
It’s a move that lines up with the ICT sector’s growing environmental responsibilities. Future-proofing networks this way seems pretty crucial for meeting ESG goals these days.
SRv6: A Backbone for Future-Ready Networks
Speed isn’t the only story. With SRv6 in the mix, the core IP backbone gets a serious upgrade in resilience, security, and smarts.
Segment Routing over IPv6 lets operators control paths precisely, which means better rerouting and fewer headaches during failures or maintenance.
Resilience That Keeps the World Connected
SRv6 can reroute around failed network links almost instantly. Even during outages, critical data flows keep moving.
This kind of reliability matters for things like financial transactions, telemedicine, and industrial IoT—stuff you really don’t want going down.
Enhanced Security and Traffic Management
With today’s cyber threats, you can’t skimp on backbone security. SRv6 gives operators tools to:
- Control and define specific traffic flows
- Enforce firewall-based routing policies
- Prioritize traffic for quality-of-service
- Mitigate some cyberattacks by steering paths
These features help protect sensitive services and keep mission-critical networks safe from ever-evolving threats.
Looking Ahead: MWC Barcelona Showcase
ZTE and MASORANGE will show off the full power of their 800G + SRv6 solution at MWC Barcelona on March 4, 2025. This public demo should give everyone a real sense of what next-generation networks might actually do for global connectivity in the coming years.
The digital economy keeps speeding up, and data use is hitting record levels. Networks now have to be faster, smarter, greener, and more secure just to keep up.
ZTE and MASORANGE are trying to meet those challenges together. Their work could help lay the groundwork for what tomorrow’s hyperconnected world really needs.
