Why data in optical fibre is 32% slower than lightData in fibre is often said to move at the speed of light. In standard fibre it moves at 204,107 km/s, 68.1% of it, because the glass slows the pulse.Co-Packaged Optics Is Killing the Pluggable TransceiverEveryone is cheering co-packaged optics for saving power. They are missing the real story: the pluggable transceiver, the most-swapped part in any AI data center, is being quietly executed.How Fiber Optics Went From Lab Experiment to Backbone of the InternetDiscover how fibre optic communication has reshaped modern communication and connected the world.Tesla vs Marconi: Who Really Invented Radio?Tesla vs Marconi: learn about the two brilliant minds who clashed in a fierce battle to develop wireless communication.Copper vs Fibre Cable: Speed, Reach and Bandwidth ComparedCopper or fibre for a data-centre link? How reach, channel checks, handling and quoted cost decide it, with three 100G examples.Is 6G a Thing? What Is Real and What Is HypeIs 6G a thing? Yes — standards work has officially started, but not the way the hype says. What is real in 2026, and what arrives by 2030.Hollow Core Fibres: How Novel Fibres Smashed Loss Records Through Air GuidanceHollow core fibres guide light in air, not glass, enabling huge leaps in speed and capacity and smashing loss records.
