A team of international researchers say they’ve set a new world speed record for an industrial standard optical fiber that’s as thick as a human hair and contains a groundbreaking 19 cores. All of the ...

OSAKA, Japan--(BUSINESS WIRE)--Sumitomo Electric Industries, Ltd. (TOKYO:5802)(ISIN:JP3407400005) has developed a new-type coupled multi-core optical fiber suitable for ultra-long-haul transmission, ...

- An optical fiber with 19 cores within a standard cladding diameter was developed, enabling a transmission capacity of 1.7 petabits per second. - Randomly coupled multi-core fibers require less power ...

Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit ...

Researchers have sent data at a record rate of 402 terabits per second using commercially available optical fiber. This beats their previous record, announced in March 2024, of 301 terabits or 301,000 ...

- 37.6 THz optical bandwidth achieved by combining 6 doped-fiber amplifier variants with lumped and distributed Raman-amplification to cover all of the low-loss transmission bands of silica fibers - ...

In Sept, 2025, Microsoft Azure announced it is scaling its hollow core fiber (HCF) production by outsourcing manufacturing to ...

What just happened? A few months ago, scientists at Aston University in the UK broke a world record for data transmission speed. They have now surpassed their previous work, achieving a new benchmark.

Japan-based optical communications partners KDDI Corp. and KDDI Research, Sumitomo Electric Industries, Furukawa Electric, and US-based OFS Laboratories have conducted successful experiments on ...
