Optical vs infrared
WebMar 29, 2024 · Fiber communication using infrared is used for 400 Gbit/s Ethernet (up to 40 km), with 800G and 1.6T currently being developed. For wireless, free-space optical (FSO) laser systems using infrared wavelengths are available for 1 and 10 Gbit/s, likely even faster. The reach is several km. Microwave commonly runs at 1 or up to 10 Gbit/s.
