We experimentally demonstrate the joint use of OFDM and channel flattening effect provided by a Fabry-Perot filter to allow higher than 25 Gbit/s direct intensity modulated, directly detected transmission  ...  We use adaptively modulated orthogonal frequency division multiplexing (OFDM) to assess the benefits brought by a Fabry-Perot (FP) filter to the DIMDD channel thanks to bit and power loading algorithms  ...  This equivalent transmitter leads to a flatter DIMDD frequency response that allows up to 25% increase of the OFDM bit-rate at 50 km SSMF and beyond 25 Gbit/s transmission over up to 75 km SSMF.  ...

Terabit-Rate Transmission Using Optical Frequency Comb Sources

Jörg Pfeifle
Such frequency combs provide a large number of carriers. The equidistance of the comb lines helps to minimize spectral guard bands.  ...  A symbol rate of 12 GBd was used for the super-channels based on the 12.5 GHz comb leading to a sub-channel line rate of 48 Gbit/s and 96 Gbit/s for the two modulation formats employed.  ...  In Refs [132] , [133] such a comb source has been used to transmit several channels operating at 10 Gbit/s and 40 Gbit/s, respectively, in a passive optical network (PON) with coherent detection.  ...

Chip-scale optical frequency comb sources for terabit communications

Pablo Marin-Palomo
With typical distances from a few kilometers to 100 km, these links require the use of a high number of WDM channels. The associated transceivers should have low cost and footprint.  ...  The scalability of the number of channels, however, is still limited by the lack of adequate optical sources.  ...  As a reference, the plot indicates the minimum OSNR required for transmission of a net data rate of 400 Gbit/s or 600 Gbit/s per WDM channel using 16QAM or 64QAM as a modulation format, respectively.  ...
