Abstract
We experimentally demonstrate a bit-rate of
47.4Gb/s over 100 m of perfluorinated multimode
graded-index plastic optical fiber (GI-POF) by exploiting discrete multitone
(DMT) modulation with rate-adaptive bit-loading. The maximum achieved
aggregate bit rate is 51.8 Gb/s including DMT transmission overhead (cyclic
prefix and preambles) and the standard of 7% of forward-error-correction
(FEC) overhead. This is achieved over an intensity-modulated
direct-detection (IM-DD) link using a directly-modulated DFB laser (1300-nm)
and a multimode fiber-coupled photodetector with a large diameter of 25-$\mu$m. The bandwidth requirement is only 12 GHz due to the use of
spectral-efficient modulation formats of up to 64-QAM.
