摘要

In August of 2020, engineers at University College London (UCL) in the United Kingdom reported a new record for transmitting data through a single optical fiber, hitting 178 terabits per second (Tbps) and beating the old mark by 20% [1]. And in June 2020, two US telecommunications companies, Sunnyvale, CA-based Infinera and Little Rock, AK-based Windstream, reached another milestone. For the first time, the collaborators maintained an 800 gigabits per second (Gbps) transmission rate in one fiber over a long distance, using a line running more than 730 km from San Diego, CA, to Phoenix, AZ, USA [2].
