100 Gbit/s Transmission using Single-Band Direct-Detection Optical OFDM

Abstract: We experimentally demonstrate a single-band direct-detection polmux OFDM system using novel colorless transmitter and pol-mux receiver architectures. We transmit 100 Gbit/s over 500 km of standard SMF with a spectral efficiency of 3.57 bit/s/Hz.

“…However, in systems where optical front-end complexity is considered a problem, such as with short-haul links, heterodyne systems may deserve consideration. Moreover, heterodyne systems require the same electro-optic bandwidths as virtual carrier direct detection systems [19,28,29], and so can be directly compared in a fair manner.…”

“…At optimum operating condition, this required spectral gap needs to be either equal to or greater than the OFDM signal bandwidth [10,11]. Therefore, in a DDO-OFDM system, at least half of the signal bandwidth remains unused, reducing the effective optical spectral efficiency (SE) enormously [12,13].…”

“…Different approaches have been proposed recently to increase the spectral efficiency of DDO-OFDM systems [12][13][14][15]. The first approach [12] introduces techniques to either avoid or use less spectral gap by applying an iterative signal processing algorithm that reduces the beat noise from the detected signal.…”

“…Since then, extensive investigations of OOFDM transceivers of various configurations have been reported in long-haul [4,5], MANs [6] and LANs [7]. However, all experimental works published so far have been undertaken using non-real-time signal processing approaches, which do not consider the limitations imposed by the precision and speed of practical digital signal processing (DSP) hardware.…”
