“…Unfortunately, filtering functions are not ideal and the tighter the filtering granularities of a ROADM, the higher the filtering penalties [31] suggesting the use of a guard-band separating OFDM channels in order to minimize the penalties due to both filtering functions and the channel cross-talk. The higher the guard-band value, the lower the advantages of flex-grid networks with respect to fixed-grid [32].…”

“…The individual channels are aggregated into one spectrally-continuous super-wavelength optical path, which can be transmitted through the core network consisting of bandwidth-variable wavelength cross-connects (WXCs). In [80], a 420 Gb/s distance-adaptive super-channel with DQPSK and 8-APSK modulation was also demonstrated.…”

Abstract-Orthogonalfrequency-division multiplexing (OFDM) is a modulation technology that has been widely adopted in many new and emerging broadband wireless and wireline communication systems. Due to its capability to transmit a high-speed data stream using multiple spectral-overlapped lower-speed subcarriers, OFDM technology offers superior advantages of high spectrum efficiency, robustness against inter-carrier and inter-symbol interference, adaptability to server channel conditions, etc. In recent years, there have been intensive studies on optical OFDM (O-OFDM) transmission technologies, and it is considered a promising technology for future ultra-high-speed optical transmission. Based on O-OFDM technology, a novel elastic optical network architecture with immense flexibility and scalability in spectrum allocation and data rate accommodation could be built to support diverse services and the rapid growth of Internet traffic in the future. In this paper, we present a comprehensive survey on OFDM-based elastic optical network technologies, including basic principles of OFDM, O-OFDM technologies, the architectures of OFDMbased elastic core optical networks, and related key enabling technologies. The main advantages and issues of OFDM-based elastic core optical networks that are under research are also discussed.

“…The concept of a flexible optical network, in which various modulation formats are used flexibly to exploit spectral resources efficiently, has been the focus of attention in recent years [24]. We devised a flexible-format optical modulator with which we can select the optimum combinations of carrier number and modulation level according to the transmission conditions [14].…”

Abstract:We review our recent progress toward transmission speeds per channel of 100 Gbit/s and beyond, focusing on optical modulators and receivers for coherent transmission using PLC integration technology. We have used PLC-LiNbO 3 hybrid integration technology to develop optical multilevel modulators, including a DP-QPSK modulator and a 64 QAM modulator for 100 Gbit/s and post 100 Gbit/s. This technology provides practical performance and scalability for various advanced modulations. We have also developed flexible-format modulators for future elastic networks, which will enable the efficient use of the spectral resource. This modulator can select an optimum carrier number and modulation level according to the transmission conditions. In terms of receivers, we have developed integrated optical receiver front-ends for 100 Gbit/s DP-QPSK based on hermetically sealed O/E converters. PLC hybrid-integration technologies are promising for compact, practical, cost-effective, and highly reliable coherent optical modulators and receivers.
