Shawline HDMI AOC 21

48Gbps – That ain't British horse power but the Chord Company's upgraded Shawline HDMI AOC 21 cable's super-fast transfer rate over active glass fiber. It's capable of "full 8K at 60Hz or 4K at 120Hz" and available in 1m [£250], 2m, 3m, 5m, 8m, 10m, 15m and 20m standard lengths. Custom lengths up to 50m are available by special order. "Unlike Toslink which carries the entire signal on optical fibres, our HDMI AOC is an advanced hybrid of seven copper cables and four optical fibres. The advantage of optical fibre is that it doesn't pick up HF noise. This potential weakness coupled with longer cable lengths means that HF noise on the signal earth is inevitable. Even though this is a digital 'optical' cable, Chord Company's engineers have ensured that the copper elements are fully protected from external HF noise pollution. Therefore beneath the external PVC jacket sits a double aluminium foil shielding system for even greater performance."
