OIF kicks off new projects: 224G PAM4, 1600ZR

OIF has kicked off four new projects:

224G PAM4 protocol agnostic link training for electrical interfaces project

Electrical interface link training holds considerable significance throughout the industry. This project will define communication method, messaging format and contents, training patterns, states and sequences, diagnostics and fault handling, etc. for link training of a 224G PAM4 class electrical link. The objective is to enhance overall link performance, a critical factor, particularly under challenging conditions, to establish a functional connection.

As part of this initiative, the CEI (Common Electrical IO) framework will be expanded with an additional tool to encompass a comprehensive solution, reinforcing OIF's leadership in the electrical/SERDES domain.

“This project is critical for OIF, yielding a standardized solution that seamlessly fosters SERDES interoperability and implementation, transcending the boundaries of specific applications,” said David Stauffer, OIF Physical & Link Layer Working Group Chair and Kandou Bus, S.A. “Through collaborative efforts with other industry groups, we aim to forge a consistent industry-wide solution that simplifies implementation.”

1600ZR Project

The 1600ZR project will define a power optimized solution for a multi-vendor interoperable 1600 Gbps coherent optical interface, with a focus on Data Center Interconnect (DCI) scenarios. This Implementation Agreement (IA) will create a comprehensive electrical/protocol/optical framework that facilitates realization into pluggable modules. It will also establish a reference point for additional applications that contribute to the growth of the coherent ecosystem.

“It has become clear that multiple evolution paths from 400ZR will be required in DCI transport,” said Ian Betty, OIF Board Member and Ciena. “While the 800ZR IA development is still ongoing, the group has started a parallel project to address the complexities of supporting 1.6T Ethernet clients in single span DCI applications for reaches of at least 80km. OIF is leading the industry by creating an IA for an interoperable 1.6T Ethernet coherent line interface designed for ZR/DCI applications. This project further validates that OIF is the platform for next-generation coherent line interface discussions and to facilitate the development of innovative applications and architectural solutions. We encourage network operators to actively participate in these efforts to help shape the specifications to best meet their needs.”

Data Center Storage and Optical Multi-layer Coordination

Transaction failures in the financial industry are sometimes attributed to network issues such as jitter, intermittent disconnection and bit errors, caused by unstable DCI links. Fast fault detection and recovery of optical connections can be leveraged to address these issues and support new DC applications, by coordinating between the application layer and optical connections in the DCI network. This project will result in a white paper that will delineate anticipated scenarios, crucial technical requirements, and potential multi-layer protection solutions, and provide a comprehensive gap analysis regarding the coordination of storage and optical connections.

“This project stands as a testament to OIF’s mission to develop interoperable solutions for challenging optical interworking applications like DCI,” said Jia He, OIF Networking & Operations Working Group Chair and Huawei Technologies Co., Ltd.

System Vendor Requirements Document for Energy Efficient Interfaces

This project will result in a requirements document for Energy Efficient Interfaces (EEI) through input gathered by system vendors from end users and provide a list of prioritized applications and a basic set of requirements for the next generation of energy efficient electrical and optical links. A primary objective of this work is to provide guidance to the EEI Framework Project and future IAs based on the framework at the OIF or other standards organizations.

“This project introduces a new area of standards for the OIF, expanding its ecosystem and industry influence,” said Jeffery Maki, OIF Physical Layer User Group Chair and Juniper Networks. “A key objective of this project is to outline user-driven prerequisites that will shape the trajectory of future EEI initiatives within the organization.”

The announcement follows OIF's hybrid Q3 Technical and MA&E Committees Meeting, which was held last monght in Vancouver.

CyrusOne plans 7th data center campus in Frankfurt

CyrusOne announced plans for its seventh data center campus in Frankfurt, named FRA7, located on a 63,000 square meter plot at FRANKFURT WESTSIDE; a 73-hectare commercial and industrial mixed-use regeneration project managed by BEOS AG and Swiss Life Asset Managers Deutschland.

This latest news from CyrusOne follows a competitive selection process in which CyrusOne was the favored partner to deliver a data center scheme that prioritizes sustainability, provides re-used waste heat to the WESTSIDE campus, and is aligned to BEOS’ commitment to create spaces that support; creativity, innovation, progress and productivity. CyrusOne’s partnership with BEOS and Swiss Life Asset Managers marks an important step in the company’s ongoing commitment to European expansion and a sustainable future.

The new facility will start with a total capacity of 81 megawatts delivered across nine data halls in two 3-story buildings. CyrusOne aims for an annualised PUE of <1.3 in advance of European energy efficiency directive targets for 2030. It will also fall in line with the anticipated energy efficiency targets proposed by German legislation.

The facility will be powered by renewable energy, as has CyrusOne’s entire operational portfolio in Europe since June 2021. In addition, specific practices are being implemented throughout the design and construction phase to source sustainable materials and lower CO2 emissions.

Sparkle activates BlueMed between Palermo, Genoa, and Milan

Sparkle activated commercial service in the first section of the BlueMed submarine cable connecting Palermo with Genoa to Milan. Service is available at multiples of 100 or 400 Gbps with a latency reduced by 50% compared to the terrestrial cables connecting Sicily with Milan today. 

BlueMed is Sparkle's new cable that will connect Italy with France, Greece and several countries bordering the Mediterranean Sea all the way to Aqaba in Jordan. The cable is part of the Blue & Raman Submarine Cable Systems, built in partnership with Google and other operators and that will extend to Mumbai. It is fully integrated with Sparkle's network, BlueMed.

Each fiber pair is lit with innovative transmission platform with throughput of 30 Tbps, which is currently the highest submarine backbone capacity per fiber pair in service in the Mediterranean region, destined to increase as the technology evolves further. 

Some additional notes:

  • The Sicily Hub neutral data center in Palermo - technological heart and intelligence of the Sparkle network, already connected with eighteen international cables landing in Sicily - is enriched with this new and innovative route to continental Europe for the benefit of service providers in Africa and the Middle East as well as of content providers exchanging traffic and digital applications on the island.
  • The Genoa Digital Hub in Lagaccio - an open and neutral colocation facility, new interconnection point for terrestrial networks and international submarine cables including Blue & Raman Submarine Cable Systems - sees the first traffic flows activated with potential to develop the city's ecosystem. The hub is also set for significant growth thanks to the Genoa Landing Platform - infrastructure designed to ensure, in addition to BlueRaman and BlueMed, the sustainable landing of up to six new submarine cables seeking diversified access to major European hubs - and the newly established Ge-DIX exchange point.
  • The fiber optic system ends its journey at the Milan hub, which has become a rich, high-growth digital ecosystem in recent years. The submarine system's attestation is developed within the STACK campus in Siziano, that offers a wide range of connectivity solutions and can connect all data centers in the Milan area as well as major national and international providers.

After the Palermo-Genoa-Milan route, activations will follow to Pomezia (Rome), Golfo Aranci (Sardinia), Bastia (Corsica) and Marseille planned by the end of 2023, and then during 2024 the other routes in the Central and Eastern Mediterranean.
