【 摘 要 】

References(6)We demonstrate a 100 Gbit/s real-time digital coherent transmission over a 32-km multi-mode graded-index fiber (GIF) with a 62.5 µm core diameter by compensating for modal dispersion with a digital signal processing (DSP). The DSP enables channel estimation and configuration as fast as 20 ms. Furthermore, the optical channel can be switched between GIF and a single-mode fiber (SMF) within 30 ms.
