EXA partners with IOEMA
Early launch for China Telecom’s ADC
China Telecom has announced that the capacity of the Asia
EXA Infrastructure has been chosen by IOEMA as the landing partner for its new submarine cable in Leiston, UK. From the cable landing station EXA will also provide backhaul connectivity to major data centres, including London Telehouse and Equinix. Launched in May 2024, IOEMA is a 1,600 km repeated high-capacity submarine fibre optic network linking five key Northern European markets: the UK, Netherlands, Germany, Denmark, and Norway. This project is a game-changer,
landing stations, serves as a critical gateway between the UK and the Netherlands via the Concerto cable. It offers low-latency direct links to London, alternative routes to Dublin and northern UK regions bypassing London, and access to multiple transatlantic pathways, further strengthening connectivity to the Nordics. Steve Roberts, SVP of Strategic Investments and Product Management at EXA Infrastructure, stated, “Being selected as the landing partner for this advanced fibre optic project highlights our expertise in delivering complex subsea landing solutions. Our commitment to providing diversity and resiliency through our extensive owned fibre network in Europe, coupled with vital transatlantic routes, positions us as a market leader in enabling advanced connectivity.”
has taken a proactive approach by coordinating closely with all consortium members and suppliers to overcome unexpected challenges and difficulties. This collaborative effort, it says, has successfully brought ADC capacity into service two months ahead of schedule, significantly alleviating the strain on submarine cable resources. The coming online of ADC capacity will provide a robust foundation for the thriving development of artificial intelligence, cloud computing, and big data, while offering support for digital transformation across industries. Looking ahead, China Telecom says it will continue to expand its footprint in overseas markets, actively developing global network resources to make even greater contributions to the advancement of the global digital economy.
Direct Cable (ADC), an international submarine cable initiative led by the operator, has gone into service ahead of schedule, two months earlier than originally planned. This, says China Telecom, marks another significant milestone following the Ready for Service of the ADC wet segment last November. The ADC launch is particularly important, according to China Telecom, because over the past eight years, no new submarine cables had been brought into operation within the Asia- Pacific region, leaving existing resources nearly exhausted and creating a challenging situation in the market. As Co-chair of the ADC Consortium, China Telecom Global Limited

Zayo taps Infinera for US 1Tbps trial
DE-CIX taps Nokia for New York IX upgrade
Zayo and Infinera have successfully completed a live network trial using Infinera’s ICE7, a seventh- generation embedded optical engine, to deliver 1Tbps single 150GHz wavelength transmission over 1,391 kilometres on a major North American route between Sacramento, CA and Salt Lake City. This, says Zayo, achievement will enable it to deliver 32Tbps of C-Band capacity across this link, with the ability to double bandwidth to 64Tbps with L-Band. Infinera’s ICE7 optical engine features a 5-nm CMOS DSP and leverages the latest generation of advanced high-speed optics to deliver high-baud-rate (140+ Gbaud) and single-
Nokia and Internet Exchange (IX) operator, have announced the upgrade of the operator’s New York backbone network, which is the largest IX in NY and in the US Northeast region. The DE-CIX backbone will be upgraded to 400 Gigabit Ethernet (GE) using Nokia optical technology and redesigned in a ring topology, redundantly interconnecting the 10 data centre facilities where DE-CIX infrastructure is housed and enhancing the resiliency of the platform for all participants. The Nokia optical solution also enables 800GE support for anticipated further growth of the IX and employs
wavelength transmission of up to 1.2 Tbps, highlighting the improved capacity- reach and significantly reduced cost per bit, power consumption, and footprint of coherent optical transport. Zayo operates the largest independent network, spanning 132,000 route miles in North America alone, and one of the largest and most modern 400G networks in North America. The success of the trial demonstrates Zayo’s ability to seamlessly integrate innovative new solutions like Infinera’s ICE7 optical engine into its network to deliver the highest capacity, speed, and efficiency to meet the growing demands of its customers.
Reconfigurable Optical Add/Drop Multiplexer (ROADM) technology to ensure much greater routing flexibility, faster reaction times in the case of incidents, and a seamless customer experience without any service interruptions. Nokia says that within a DWDM system, the ROADM technology in Nokia’s 1830 Photonic Service Switch (PSS) makes it possible to automatically reroute waves at the optical layer in any direction around the backbone. This means that incidents at any location in the network can be mitigated more rapidly and less capacity is required at the IP layer to guarantee the same level of resilience.
