Compared to conventional metallic cables, optical fiber provides an advantage of low loss (~ 0. 2dB/km) and wide bandwidth (several hundred MHz to THz) to enable long-distance, high-capacity communication. 5km by applying large-scale MIMO 1 signal processing technology in a terrestrial field environment in which a 12-core fiber with the same diameter as existing. DWDM technology allows multiple optical carrier signals (each on a different wavelength/laser color) to be transmitted simultaneously on the same fiber. Think of it as turning a single-lane road into a massive, multi-lane super-highway. Utilizing light waves to transmit information, this technology offers signifi cant advantages, including high bandwidth, low attenuation, and minimal interference compared. In this press release, we announce the success of our transoceanic long-distance transmission experiment over 7,280 km using 12-core optical fiber.
