Cisco 800G ZR/ZR+ Coherent Optics
Transmit 800G wavelengths up to 120km with coherent ZR, and over 1000km with OpenZR+. QSFP-DD and OSFP form factors double the capacity of 400G links for AI and hyperscale data center interconnect.
Product Overview
800G Capacity
Double the bandwidth of 400G coherent optics with a single wavelength, maximizing fiber utilization for AI and hyperscale workloads.
ZR: Up to 120km
Standards-based 800G ZR for metro data center interconnect over amplified DWDM links up to 120km.
ZR+: Over 1000km
OpenZR+ extends reach beyond 1000km with enhanced FEC and flexible modulation for long-haul and regional networks.
Eliminates Transponder Shelves
Plug coherent optics directly into routers and switches, removing the need for external transponder chassis and reducing cost.
7nm DSP Technology
Advanced 7nm digital signal processing delivers high performance with low power consumption in a compact pluggable form factor.
Routed Optical Networking
Converge IP and optical layers into a single architecture, simplifying network operations and reducing total cost of ownership.
Features and Benefits
Next-generation coherent optics for AI-scale networks.
The 800G ZR/ZR+ pluggable optics deliver the highest capacity per wavelength in industry-standard form factors for data center interconnect and beyond.
800G Single Wavelength
16-QAM modulation delivers 800 Gbps on a single DWDM wavelength, doubling spectral efficiency over 400G.
Dual Form Factors
Available in both QSFP-DD and OSFP to match your platform and deployment requirements.
oFEC Error Correction
Open forward error correction provides superior coding gain for reliable transmission over extended distances.
IP-Optical Convergence
Collapse the optical transport layer into the router, reducing equipment, power, and operational complexity.
AI-Ready Bandwidth
Purpose-built for GPU cluster interconnects and distributed AI training that demand massive east-west bandwidth.
Power Efficient
7nm DSP technology minimizes power per bit, reducing cooling costs in high-density deployments.
