A team of researchers from the National Institute of Information and Communications Technology (NICT) in Japan is at it again. After achieving a data transmission speed of 319 terabits per second (Tb/s) last year, the researchers have now absolutely smashed their own previous achievement by transmitting data at 1.02 petabits per second (Pb/s).

Since 1 petabits is 125,000 gigabytes, it means that the team could theoretically transmit more than 31,000 movies in 4K resolution every single second. To make the record even more impressive, it’s important to highlight that it was achieved using fiber-optic cables with four cores, which is exactly how many cores were used to set the previous record.

“NICT constructed the transmission system using 4-core MCF with standard 0.125 mm cladding diameter, WDM technology and mixed optical amplification systems. The system allowed a data transmission speed of 1.02 petabit per second over 51.7 km,” explained the researchers in the official press release.

The mind-blowing record was first presented in May at the International Conference on Laser and Electro-Optics (CLEO) 2022 in San Jose, California, one of the largest international conferences related to optical devices and systems.

Moving forward, the NICT team wants to continue exploring different ways to transmit data faster across fiber optic cables. Their main focus is on low-core-count multi-core fibers with standard cladding diameter because such cables are comparable to standard single-mode fibers and thus more attractive for early adoption.

With dozens of countries around the world actively moving from 4G to 5G broadband cellular networks, the massive amount of data being sent and received is guaranteed to continue increasing at a rapid pace. Research projects such as the one behind the latest record can pave the way for new fibers capable of meeting the growing demand and supporting new bandwidth-hungry services.

UAE’s Etihad Rail Launches In 2026 — What You Need To Know

A 1,200 km passenger network will transform public transport, with 11 connected cities, and high-speed trains cutting inter-emirate travel times.

Etihad Rail has confirmed that its long-anticipated passenger train service will officially launch in 2026, ushering in a new era of high-speed, inter-emirate travel. The UAE’s national railway developer shared the announcement on X (formerly Twitter), as work continues on a 1,200 km passenger network set to connect 11 cities across all seven emirates.

The news marks a major leap in public transportation for the country, with passenger trains designed to reach speeds of up to 200 km/h. Travel times will be significantly reduced — Abu Dhabi to Dubai is expected to take just under an hour, while the journey to Fujairah will be cut to around 105 minutes. A separate high-speed line, capable of reaching 350 km/h, is also in the works to link Abu Dhabi and Dubai in just 30 minutes.

The backbone of the network was completed in 2023, when Etihad Rail launched its 900 km freight service linking key industrial and logistics hubs across the UAE, including ports in Abu Dhabi, Dubai, and Fujairah. Now, the focus has shifted to passenger infrastructure.

The first station will be located in Sakamkam, Fujairah city centre, and a second is confirmed near University City in Sharjah. Dubai’s main station is expected to be adjacent to Jumeirah Golf Estates Metro Station, while Abu Dhabi’s is anticipated along the corridor separating Mussafah Industrial Area and Mohammed Bin Zayed City.

Once completed, the passenger network will link cities including Al Sila, Al Ruwais, Al Mirfa, Dubai, Sharjah, Al Dhaid, Abu Dhabi, Ras Al Khaimah and Fujairah. Integration with Oman is also part of the long-term vision. A new cross-border project — Hafeet Rail — will span 303 km between Sohar and Abu Dhabi’s Al Wathba area. Developed by Etihad Rail in collaboration with Oman Rail and Mubadala, the link is expected to deepen trade and tourism ties between the two countries.

Etihad Rail’s passenger trains will carry up to 400 passengers each and feature Wi-Fi, entertainment systems, charging points, and onboard food and beverage options to ensure a comfortable experience. To further simplify access, passengers will be able to pay with their nol cards, thanks to a partnership between Etihad Rail and Dubai’s Roads and Transport Authority (RTA). The collaboration aims to integrate fare payments and booking systems under one unified platform.
