translation.en: that look kind of like bluefin tuna, and every 50 miles they amplify the signal, and since the rate of transmission is incredibly fast, the basic unit is a 10-gigabit-per-second wavelength of light, maybe a thousand times your own connection, or capable of carrying 10,000 video streams, but not only that, but you'll put not just one wavelength of light through one of the fibers, but you'll put maybe 50 or 60 or 70 different wavelengths or colors of light
translation.zh: 它们看起来像蓝鳍吞拿 每50英里 它们会增强信号 由于传播速度 无比迅速 基本单位是每秒10千兆比特 光波 也许是你连接速度的一千倍 或能承载1万个视频流 但不止那样 你不会只把一个光波 放在一条光纤里 你也许会在一根光纤里放 50或60或70个不同波长或颜色的光波
