Cisco, Microsoft tap Acacia for 800Gbps subsea services
Ubiquity, Fujitsu partner for last-mile support
Fujitsu Network Communications, Inc. says that digital infrastructure
and associated economic development. Fujitsu’s managed network services include fault monitoring, notification, troubleshooting and onsite dispatching. As a result, Ubiquity has realised accelerated visibility into and management of sustainable infrastructure, delivering premium broadband services faster to new markets cost- effectively. “We relied on Fujitsu’s experienced staff and efficient processes to meet our aggressive monitoring and resiliency needs to deliver the future of sustainable digital infrastructure,” said Ajay Ghanekar, co-founder and co-CEO, Ubiquity. “Fujitsu support made it possible for us to keep pace with our significant build plan, support a varied set of customers and maintain a consistent set of quality on our fibre service.”
Cisco and Microsoft have successfully
transmitted over 12,469 kilometres for a trans-Atlantic loopback configuration. This is the first time a 140Gbaud single carrier signal was demonstrated live, and is the longest distance ever reported at single carrier 600G DWDM transmission on an SDM cable. Amitié submarine cable features Space Division Multiplexing (SDM) technology with 16 fibre pairs, more than traditional subsea cables, with repeater power shared across the fibre pairs to deliver the highest cable capacity. Cisco adds that the need for greater subsea network capacity, which requires advanced coherent transmission systems that support higher performance is largely being driven by the continued growth of cloud and explosion of AI services.

transmitted 800Gbps on the Amitié transatlantic communications cable, which runs 6,234 kilometres from Boston, Massachusetts to Bordeaux, France. The trial was performed with the Cisco NCS 1014 platform enabled by Acacia’s Coherent Interconnect Module 8 (CIM 8), which is powered by its Jannu digital signal processor and advanced silicon photonics. Cisco says this real-time field trial exceeded any industry trial performance to date with Dense Wavelength Division Multiplexing (DWDM) 800G in a 150GHz channel spacing, equivalent to a spectrum efficiency of 5.33bps/Hz and a maximum spectral efficiency of 5.6bps/ Hz. In addition, 600G was
Centre (NOC) to support last-mile, fibre broadband infrastructure in four major U.S. markets. Fujitsu provides Ubiquity with 24x7 managed network services from their carrier-class NOC in Texas. Ubiquity is a digital infrastructure owner, developer and operator with the nation’s largest and fastest-growing open access, fibre-to-the-premise (FTTP) network. With a commitment to delivering high-capacity broadband networks, Ubiquity enables fast-growing suburban communities as well as underserved communities to reap the benefits of affordable, high- speed connectivity options
Top firms trial hollow core fibre
Telia Lithuania taps Ciena for 800Gbps wavelength service
lyntia, Nokia, OFS|Furukawa Solutions and Digital Realty (Interxion) have successfully carried out a field trial in a real environment to demonstrate the potential of hollow core fibre technology. Prior to implementing the technology in a real environment, pilot
The recently completed field trial in Madrid confirms the feasibility and effectiveness of hollow core technology. The trial demonstrated a round-trip latency reduction of 4.287μs over a 1.386km link; a latency reduction of more than 30% relative to conventional single mode fibre. The capacity deployed during the field trial was 6x100Gbps on a single 600Gbps wavelength, and 10x10Gbps on a single 100Gbps wavelength. lyntia’s strategic location in Madrid served as the starting point from which a 1.4km link was deployed to a Digital Realty (Interxion) data centre using AccuCore® HCF fibre optic cable developed by OFS| Furukawa Solutions. In addition, Nokia provided the transmission equipment and field and lab testing.
Telia Lithuania, a Telia Company subsidiary, is deploying Ciena’s WaveLogic 5 Extreme
Ciena optical and network management solutions including Ciena 6500 packet-optical platform powered by WL5e and WaveLogic Ai programmable coherent optics Ciena says the upgrade will mean increased capacity, network reach, and power efficiency; faster wavelength restoration with the 6500’s flexible photonics and intelligent Layer 0 control plane; quicker issue resolution and improved timing distribution for applications requiring highly reliable synchronisation; and simpler service deployment and network operations with Navigator Network Control Suite (Navigator NCS).
(WL5e) coherent optics to upgrade its countrywide network to support 400G and higher services and deploy the first 800Gbps wavelength service between major cities in Lithuania. With this deployment, Telia Lithuania says it will be able to deliver more flexible, higher-capacity, and cost- effective transport services with the resiliency and power efficiency required by 5G, Internet of Things (IoT), and other bandwidth- intensive applications. Telia Lithuania’s new network will also utilise additional
tests were carried out in a laboratory in Paris by
Nokia Bell Labs. The initial results showed a significant reduction in latency by more than 30% and a considerable decrease in non-linear effects compared to traditional optical fibre. The pilot tests in Paris demonstrated data rates of 800 Gbps and 1.2 Tbps. The results showed that hollow fibres have the potential to break through the non-linear Shannon capacity limit of solid-core fibres.
