European consortium IOEMA 1 Holding has partnered with advisory firm APTelecom to develop IOEMA-1, a petabit-class subsea cable spanning 1,600 kilometers across the Netherlands, Germany, Denmark, Norway, and the United Kingdom. The 24-fiber-pair system, designated a strategic project by the European Union, is targeted for service in Q1 2029. The initiative competes alongside Japan’s NEC and NTT, who successfully trialled multicore fiber transmitting hundreds of terabits over 7,280 kilometers, and Meta’s Project Waterworth, as surging AI-driven bandwidth demand accelerates the global race for next-generation submarine infrastructure.

European consortium IOEMA 1 Holding has announced a strategic partnership with advisory firm APTelecom to advance a petabit-class subsea cable system.
This planned 24-fiber-pair network spans roughly 1,600 kilometers across five Northern European nations, aiming to connect digital hubs in the Netherlands, Germany, Denmark, Norway, and the United Kingdom.
The consortium expects this underwater cable system to become ready for service during the first quarter of 2029.
Japanese corporations NEC and NTT have already successfully trialled a revolutionary submarine cable technology utilizing 12-core multicore fiber, which packs twelve optical signal transmission paths within a standard outer diameter optical fiber.
Existing submarine cables typically rely on single-core fiber with only one transmission path.
The Japanese team transmitted hundreds of terabits across a staggering distance of 7,280 kilometers, with a sophisticated algorithm solving the interference problem known as crosstalk between neighboring cores.
NEC developed a demodulation algorithm utilizing MIMO technology to separate overlapping signals accurately, and NTT simultaneously created a coupled multicore fiber transmission line that manages signal delay non-uniformity.
Similarly, Meta is building subsea infrastructure across the globe to relocate information for billions of daily utilizers.
The company employs submarine cable systems engineers who work conclude-to-conclude on these massive projects.
Their responsibilities span capacity planning, route design, ocean surveys, manufacturing oversight, and deployment strategy.
More than 95% of intercontinental internet traffic rides on subsea cable systems today, and reliability is not optional for a company operating at Meta’s enormous scale.
The company is pursuing Project Waterworth, which would become the world’s longest subsea cable system.
Each of these efforts faces different technical and financial hurdles on its own timeline.
The Japanese technology has been demonstrated successfully, but full commercial deployment remains unproven at scale, and European infrastructure projects often face regulatory delays that push tarobtain dates years beyond initial estimates.
Meta has not publicly committed to a specific completion date or petabit capacity for Waterworth.
The explosion of artificial innotifyigence demand for bandwidth is real and pressing for operators, however, submarine cables typically take five to seven years from planning to actual operation underwater.
Subsea cable development
The European Union has recognized this cable as a project of European interest under its Connecting Europe Facility.
“Partnering with APTelecom brings additional deep expertise and wide-ranging market access at an important juncture in IOEMA’s development of our first cable system, IOEMA-1,” stated Andrew Parsons, Chief Commercial and Strategy Officer of IOEMA.
APTelecom declares it will contribute advisory expertise in carrier engagement, infrastructure strategy, and market strategy.
“IOEMA-1 is a strategically important project that addresses the growing demand for resilient, high-capacity connectivity across Northern Europe,” stated Sean Bergin, President of APTelecom.
“We are excited to support the team in engaging the market and driving the project toward successful delivery.
