Abstract

We investigate C+L+S long-haul systems using a closed-form GN/EGN non-linearity model. We perform accurate launch power and Raman pump optimization. We show a potential 4x throughput increase over legacy C-band systems in 1000 km links, using moderate S-only Raman amplification. We simultaneously achieve extra-flat GSNR, within ±0.5 dB across the whole C+L+S spectrum.

利用封闭式 EGN 模型优化长途 C+L+S 系统

我们利用闭式 GN/EGN 非线性模型研究了 C+L+S 长途运输系统。我们进行了精确的发射功率和拉曼泵优化。我们表明，在 1000 公里链路中，使用适度的纯 S 拉曼放大，吞吐量可能比传统 C 波段系统提高 4 倍。同时，我们在整个 C+L+S 频谱上实现了 ±0.5 dB 范围内的超平 GSNR。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
