OIF published its new 800ZR coherent interface implementation agreement (IA).
The 800ZR IA provides a framework for an 800G coherent line interface over single-span, amplified Dense Wavelength Division Multiplexing (DWDM) links of 80-120 km, optimized for data center interconnect (DCI) applications. Updates to the foundational 400ZR IA also address key performance parameters, aiming to enhance interoperability in existing 400ZR deployments.
The 800ZR IA specifies Ethernet client interfaces from 100GE up to 800G aggregate bandwidth, detailing required client mappings, frame formats, forward-error correction (FEC), modulation, and optical properties for low-power, compact coherent solutions in pluggable modules. OIF demonstrated the first multivendor interoperability for 800ZR at ECOC 2024, underscoring the readiness of 800G DCI solutions for broader adoption. The new 400ZR IA (3.0) revisions also clarify parameters to support seamless 400ZR deployments across industry networks.
- 800ZR IA supports up to 800G bandwidth for DCI on single-span DWDM links (80-120 km).
- Features low-power coherent solutions in high-density pluggable modules.
- 400ZR IA (3.0) updates focus on improving interoperability and clarifying parameters.
- Demonstrated multivendor interoperability at ECOC 2024.
- Significant uptake of 400ZR for cost-effective, interoperable DCI solutions.
“Building on the success of our 400ZR, the 800ZR IA expands capacity and efficiency for next-gen data center interconnects,” said Karl Gass, Vice Chair of OIF’s PLL Optical Working Group.
