At MWC Barcelona 2024, Huawei launched the Huawei OptiXtrans DC908 Pro, a new platform for Data Center Interconnect (DCI) designed for the intelligent era. This innovative platform ensures the efficient, secure, and stable transmission of data between data centers (DCs), setting a new standard for DCI networks. As AI continues to proliferate across various service scenarios, the demand for foundation models has intensified, leading to an explosion in data volume. DCs are now operating at the petabyte level, and DCI networks have evolved from single-wavelength 100 Gbit/s to single-wavelength Tbit/s.

In response to the challenges posed by massive data transmission in the intelligent era, Huawei introduces the next-generation DCI platform, the Huawei OptiXtrans DC908 Pro. Compared to its predecessor, the DC908 Pro offers higher bandwidth, reliability, and intelligence.

Jabil Inc., a global leader in design, manufacturing, and supply chain solutions, today announced it will take over the manufacture and sale of Intel's current Silicon Photonics-based pluggable optical transceiver ("module") product lines and the development of future generations of such modules.

"This deal better positions Jabil to cater to the needs of our valued customers in the data center industry, including hyperscale, next-wave clouds, and AI cloud data centers. These complex environments present unique challenges, and we are committed to tackling them head-on and delivering innovative solutions to support the evolving demands of the data center ecosystem," stated Matt Crowley, Senior Vice President of Cloud and Enterprise Infrastructure at Jabil. "This deal enables Jabil to expand its presence in the data center value chain."

Comcast, the nation's largest gig-speed Internet provider, today demonstrated the fastest-yet speeds it has achieved over a complete 10G connection on a live network, reaching download speeds faster than 8 gigabits per second (Gbps) and upload speeds faster than 5 Gbps. At an industry 10G event at CableLabs headquarters, Comcast also showed the 10G node technology that will help power its deployments and demonstrated how its network virtualization technology will seamlessly orchestrate mixed fiber and 10G deployments. 10G is the technology that will enable Comcast and other network operators to deliver multigigabit symmetrical speeds - combined with improved latency, security, and reliability - over the connections already installed in tens of millions of homes and businesses worldwide.

For the demo, Comcast connected a 10G-enabled Virtualized Cable Modem Termination System (vCMTS) linked by more than 80 kilometers of fiber to the demonstration site. The fiber terminated into a production switch, which connected to what is believed to be the world's first fully functional 10G-enabled Full Duplex DOCSIS 4.0 node, along with a 10G prototype modem at CableLabs headquarters. Today's demonstration is a first in a production-ready network environment, showing how live 10G deployments will work, orchestrated by Comcast's Distributed Access Architecture (DAA) technology, which is already widely deployed.

ADVA today announced that CSC - IT Center for Science, which operates the Finnish University and Research Network (FUNET) and the Swedish University Computer Network (SUNET), have conducted a world-first trial carrying data at 400Gbit/s over more than 10,000 km. Using both FUNET and SUNET, the demo harnessed the ADVA FSP 3000 TeraFlex CoreChannel to transmit services at unprecedented line speeds for a live ultra-long-haul network. The trial shows how data-intensive applications can be connected over inter-continental distances using existing links. This offers significant benefits to FUNET and SUNET customers in the R&E community who will be able to leverage high-throughput technologies and collaborate by sharing huge data sets over longer distances than ever before.

"Our multi-domain field trial with the ADVA FSP 3000 TeraFlex CoreChannel terminal evaluated flexibility and the terminal's capabilities to adapt to use cases where ultra-long-haul 400GbE services are needed. The results that were achieved - trans-oceanic reach over terrestrial systems - were far beyond our expectations and typical real-life service requirements," said Jani Myyry, senior network specialist at FUNET. "Nordic research and education networks are shifting towards a federated next-generation model where optical spectrum resources are shared within the region. We have already built multiple programmable cross-border interconnection links between the FUNET and SUNET ADVA open line systems to exchange spectrum transparently. The trial utilized these interconnection links and the FUNET and SUNET network footprint to create the extremely transparent optical routes used during the tests."

A joint team of researchers from Australia's Monash, Swinburne and RMIT universities have developed a new interpretation of the current fiber optic infrastructure - one that managed to deliver a 44.2 Tbps throughput via existing optical lines. The achievement, which delivers speeds in excess of 1 million times greater than the average home users' internet speed (50.2 megabits per second for the US), paves the way for upgrades on the existing fiber optic network that hugely decrease costs compared to the need to implement a wholly new infrastructure.

The feat was achieved using a microcomb - a device which is able to replace a number of the currently in-use lasers for the transmission of information. A microcomb is an optical device that generates very sharp and equidistant frequency lines in a tiny microphotonic chip, and it allows researchers to make use of not only the presence of light - as it's done with the usual lasers found in optical equipment - but the lack of light as well, in what researchers call "dark" pulses of light. While nowadays no user would ever need transmission speeds in the order of the 44.2 Tbps achieved by the researchers, advancement in processing, communication technologies, and supercomputing will eventually make use of these - and even higher - throughputs, which is why it's so important that this technology has been developed on top of existing infrastructure.
