Long-distance optical fiber communication
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. Utilizing light waves to transmit information, this technology offers signifi cant advantages, including high bandwidth, low attenuation, and minimal interference compared. In the demonstration experiment, we demonstrated a high-capacity transmission of 455 terabits per second over a transmission distance of 53. 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.
