First tests of manycore fibres hailed as success over oceanic distances
The two will detail their efforts at next week's Optical Fiber Communication Conference – the world's pre-eminent forum on the topic. On Thursday theyAs the partners explained, current submarine cables"use single-core fiber, which has a single optical transmission path called a core within a single fiber."
But optical networking boffins are working on multicore fibers that add more paths, without increasing the 0.125 millimeter diameter of each strand. NTT and NEC worked with fibers that packed a dozen cores into that tiny space.If only it weren't for those pesky laws of physics, which mean crosstalk occurs between cores and degrades communications.
NEC and NTT reckon they could have this tech ready to deploy in the 2030s – just in time to help networkers handle the flood of data expected to be created by the debut of 6G networks. ®FCC ups broadband benchmark speeds, says rural areas still underservedUnderwater cables in Red Sea damaged months after Houthis 'threatened' to do just that
