Schematic studies of 10 Gb/s transmission over MMFs

摘要

10 Gb/s 200 m MMF (multimode fiber) system is realized by WDM without special launching techniques. 5 Gb/s 200 m single channel MMF transmissions are realized by depressing high order modes. FP laser can be used to transmit 2.5G b/s over 500 m MMF by offset launching. Due to the speed limit (>4 Gb/s) of FP lasers, single channel 10 Gb/s transmission can only be achieved with DFB lasers.
