摘要

利用级联激光二极管泵浦/掺铒光放大器和高速多量子阱激光器，实验证明了通过标准单模光纤将编码为140 Mb/s的64个数字HDTV频道分配给262144个用户。采用直接检测技术的多千兆时分复用(TDM)方法。论证了利用光放大器和无源光网络将数字电视分配到数千用户的可行性。不使用光学滤光器，并且非常稀疏地使用光学隔离器，以降低每个用户的成本。

10 Gbit/s to 260000 subscribers using optical amplifier distribution network

The distribution of 64 digital HDTV channels coded at 140 Mb/s to 262144 subscribers via standard single-mode fiber was experimentally demonstrated using cascaded laser-diode-pumped/Er-doped optical amplifiers and a high-speed multiquantum-well laser. A multigigabit time division multiplexing (TDM) approach with direct detection technology was used. The feasibility of digital TV distribution to several thousand subscribers by using optical amplifiers and a passive optical network was shown. No optical filters were used and optical isolators were used very sparsely to reduce the cost per subscriber.<>
