OIF publishes 400ZR implementation agreeement

OIF published the Implementation Agreement (IA) for a low-cost, 400ZR coherent optical interface.

OIF launched the 400ZR project in response to requests from large-scale data center operators and their suppliers for an interoperable coherent interface that transports 400 Gigabit Ethernet over longer distances. Traditional network operators also became interested in 400ZR for their metro needs. Based on their different requirements, OIF developed specs and tweaked the channel requirements so the IA would benefit both data center and network operators. While developing the IA, OIF collaborated closely with other standards bodies.

The 400ZR IA addresses two applications:

  • Amplified, point-to-point DWDM links with reaches of 120 km or less
  • Unamplified, single wavelength links with a loss budget of 11dB


The IA aims to enable interoperable, cost-effective, 400Gbps implementations based on single-carrier coherent DP-16QAM modulation, low-power DSPs supporting absolute (Non-Differential) phase encoding/decoding, and a Concatenated FEC (C-FEC) with a post-FEC error floor <1 .0e-15.="" 400gbase-r="" 400zr="" a="" as="" operates="" p="" phy.="">

No restriction on the physical form factor is implied by the IA (QSFP-DD, OSFP, COBO, CFP2, CFP8), but the specifications target a pluggable DCO architecture with port densities equivalent to grey client optics.

“As a member driven organization, OIF’s work toward the 400ZR IA was the combination of significant interest from network operator members and component supplier members responding to that demand,” said Karl Gass, OIF Physical and Link Layer (PLL) Working Group – Optical Vice Chair. “The 400ZR IA is the culmination of this significant effort by OIF member companies and is critical for managing cost and driving interoperability for the industry.”

“400ZR is a key enabler of Microsoft’s regional architecture for the 400G generation,” said Mark Filer, Principal Optical Engineer in Microsoft Azure. “The creation of a multi-vendor, interoperable coherent interface to meet these needs would not have been possible without the extensive work and cooperation of OIF members and leadership.”

“The 400ZR IA is an example of OIF’s ability to quickly and effectively mobilize opinion and to bring interoperability to a rapidly evolving world,” said Andrew Schmitt, Directing Analyst at Cignal AI. “The 400ZR specification is the organization’s first step to establish broader interoperability among coherent transport interfaces.”

Vodafone tests Metaswitch's 5G convergence Access Gateway Function

Vodafone has successfully tested Metaswitch's Access Gateway Function (AGF) solution - the industry’s first implementation of the 5G Wireless Wireline Convergence (WWC) AGF standard.

Metaswitch said its Access Gateway Function (AGF), which is part of its 5G Fusion Core, is a true cloud-native solution in which all functional elements, including User Plane Function (UPF) and Access Gateway Function (AGF), are deployed in containers and orchestrated by Kubernetes to ensure strong performance and network deployment flexibility for service providers.

5G Wireless Wireline Convergence offers a path to a fully converged broadband access network that serves both wireline and mobile subscribers from a single technology stack. This facilitates the use of common credentials, authentication and a unified approach to applying network policy.  When fully implemented, WWC seamlessly integrates fixed and wireless services, simplifying service provider offerings, reducing the overall complexity of subscriber and service management, and promoting always-on services through converged connectivity.

The Metaswitch Fusion Core 5G WWC solution includes an Access Gateway Function built to align with the new Broadband Forum TR-456 specification, in addition to other 5G packet core functions including the world’s highest-performance software UPF. The Fusion Core UPF and AGF are both powered by Metaswitch’s Composable Network Application Processor (CNAP) software packet processing technology, which in recent tests conducted with Intel demonstrated 500 Gbps UPF throughput on a single two-socket industry-standard server.

The trial system was deployed remotely at Vodafone Labs in the UK, taking advantage of the automation capabilities of Kubernetes and Helm, and has successfully demonstrated the attachment of standard fixed network residential gateways (FN-RG) to the 5G packet core, with mapping between wireline broadband and 5G authentication, authorization and session establishment procedures performed in the AGF.

“We have been very active in supporting the Wireless Wireline Convergence activity in the Broadband Forum,” said Gavin Young, Head of Fixed Access Centre of Excellence at Vodafone Group, “and we are proud to be hosting the world’s first operator test of this technology. Working with Metaswitch, we have been able to prove that the technology works in practice, and we have been very impressed both by the performance of the AGF in Metaswitch’s 5G Fusion Core solution and its cloud native architecture. This trial more than justifies our faith in the value and the practicality of broadband convergence.”
