At speeds of up to 5 Gbit/s, the USB 3.0 quickly becomes the new standard in data transmission technology for PCs and laptops. Some computers have only 10/100 Ethernet ports, while MacBook Airs and often ultrabooks do not have any Ethernet ports at all. The existing USB 2.0 Gigabit Ethernet adapters are limited by the USB 2.0 to a maximum data transfer speed of 480 Mbps, while our USB 3.0 adapter can achieve speeds of 5 Mbps. Enhance the 3.0 Ethernet connection to super-fast gigabit speeds, or introduce true USB Gigabit Ethernet connectivity on an ultrabook or MacBook Air. https://elecena.pl/product/18333123/eu-4308-docking-station-port-replicator-usb-type-c 2021-05-05 https://elecena.pl/product/18333123/eu-4308-docking-station-port-replicator-usb-type-c 2025-01-29
