“…The ISD can be increased to 1 b/s/Hz with optical sideband or narrow filtering. Vestigial sideband (VSB) OOK experiments have been reported with ISDs of from 0.64 to 1 b/s/Hz [10]- [15]. Moreover, return-to-zero (RZ) OOK pulses with duty cycles of 33%, 50%, and 67% (carriersuppressed RZ (CS-RZ)) can be generated using a pulse carver, typically a Mach-Zehnder modulator driven sinusoidally [16].…”

The ability to transmit signals with high information spectral density (ISD) using low-complexity and cost-effective transceivers is essential for short-and medium-haul optical communication systems. Consequently, spectrally efficient direct detection transceiver-based solutions are attractive for such applications. In this paper, we experimentally demonstrate the wavelength-division multiplexed (WDM) transmission of 7×12 GHz-spaced dispersion pre-compensated Nyquist pulse-shaped 16-QAM subcarrier modulated channels operating at a net bit rate of 24 Gb/s per channel, and achieving a net optical ISD of 2.0 b/s/Hz. The direct detection receiver used in our experiment consisted of a single-ended photodiode and a single analog-todigital converter. The carrier-to-signal power ratio at different values of optical signal-to-noise ratio was optimized to maximize the receiver sensitivity performance. The transmission experiments were carried out using a recirculating fiber loop with uncompensated standard single-mode fiber and EDFA-only amplification. The maximum achieved transmission distances for single channel and WDM signals were 727 and 323 km below the bit-error ratio of 3.8 × 10 −3 , respectively. To the best of our knowledge, this is the highest achieved ISD for WDM transmission in direct detection links over such distances.Index Terms-Digital signal processing, direct detection, information spectral density, Nyquist pulse shaping, optical fiber communication, single sideband signaling, subcarrier modulation, transceiver design, wavelength division multiplexing.

“…High-performance future telecommunication networks will be based on the dense wavelength division multiplexing (DWDM) [1,2] technique, and on signals that will be processed at node sites by means of all-optical devices such as optical cross connects (OXC), optical add drop multiplexers (OADM), and all-optical wavelength converters (AOWC) [3]. Furthermore, due to traffic growth and to the ever-increasing number of accomplishments within 40-Gbit/s field trials, we believe that future telecommunication transport networks, especially those operating over wide geographical areas, will be based on N × 40 Gbit/s transmission systems [4], even though the network design in this environment requires many ingenious contrivances [5][6][7].…”

“…3.2-Tb/s [1] and 2.5-Tb/s [2] WDM field transmission experiments based on 40 Gb/s per channel have already been reported, representing the ongoing progress and positive prospects for 40-Gb/s systems. Recently, the development of multi-terabit terrestrial transmission systems has focused on increasing the capacity per fiber and increasing the un-regenerated system reach using 40-Gb/s DWDM [3][4][5][6][7]. Using 100-km, single-fiber-type spans and 40-Gb/s line rate, 3.2-Tb/s transmission over 2000 km of fiber [5] and 2.5-Tb/s over 4000 km of fiber [6] have been demonstrated in laboratories, while 10 Tb/s transmission has also been demonstrated using S-, C-and L-bands [7].…”

“…As shown in [1][2][3][4][5][6][7], distributed Raman amplification is a powerful technique to ease noise performance and to increase available bandwidth. However, there are many issues to be considered in the system design, for example, the ratio of Raman gain, gain ripple, ASE noise, MPI and non-linearity.…”

As system architectures are pushed to the limit to provide ever-increasing capacities, 40-Gb/s DWDM appears to be the next technology that will be commercially deployed. This paper reviews some of the key enabling technologies for high capacity 40-Gb/s transmission, including distributed Raman amplification, new optical fibers, advanced modulation formats, and forward error correction. It will also explain system design trade-offs and discuss several recent large-scale system transmission experiments for multiple terabit ultra-long haul terrestrial networks.
