TL;DR: A possible methodology to evolve transport networks to encompass the potential that both WDM and OTDM have to offer is outlined and can be used to achieve extremely high data-rate bit interleaved systems.
Abstract: The recent advances in optical time division multiplexed (OTDM) systems and components research show the technique to be highly suited to the generation and transmission of high capacity data on a single optical carrier. This approach uses a single wavelength to carry capacities of at least 40 Gb/s. Such systems are based on a clock frequency and tributary data rates which are easily accessible using electronic components. Short optical pulses are used in a return-to-zero data transmission format with temporal interleaving to map a number of optical data channels into a single electronic clock cycle. It is an approach that can be used to achieve extremely high data-rate bit interleaved systems. This article summarizes the developments in this field and outlines a possible methodology to evolve transport networks to encompass the potential that both WDM and OTDM have to offer. >

TL;DR: In this article, the authors discuss the requirements for realizing long-haul DSDM transport systems using multicore and/or multimode fiber, including power and space efficient amplification schemes, the use of fibers with large effective areas and transmission lines with low intercore crosstalk, low differential mode delay (DMD), and low mode dependent loss (MDL).
Abstract: In this paper, we review recent progress on space division multiplexed (SDM) transmission and our proposal of dense SDM (DSDM) with more than 30 spatial channels toward capacities beyond petabit/s. Furthermore, we discuss the requirements for realizing long-haul DSDM transport systems using multicore and/or multimode fiber, including power and space efficient amplification schemes, the use of fibers with large effective areas and transmission lines with low intercore crosstalk, low differential mode delay (DMD), and low mode dependent loss (MDL). Graded index heterogeneous 12-core × 3-mode fiber with low crosstalk, low DMD, and low MDL, parallel multiple-input and multiple-output signal processing, low mode dependent gain Erbium-doped fiber amplifiers, and MDL equalization technologies are significant as regards extending the reach of multicore and multimode transmission. We review our long-distance transmission experiment on polarization-division multiplexed 16-quadrature amplitude modulation signaling over 12-core × 3-mode fiber.

TL;DR: A directly modulated 850nm VCSEL-based optical link operating error free (BER <; 1E-12) at 64Gb/s over 57m of OM4 multimode fiber is reported.
Abstract: We report a directly modulated 850nm VCSEL-based optical link operating error free (BER < 1E-12) at 64Gb/s over 57m of OM4 multimode fiber. At 60Gb/s, the error free distance increases to 107m.

TL;DR: By combining a special dispersion map that has nearly constant path-average dispersion, a hybrid amplification scheme involving backward-pumped Raman gain, and sliding-frequency guiding filters, this work has demonstrated massive wavelength-division multiplexing at 10 Gbits/s per channel, error free, without the use of forward error correction, over greater than 9000 km.
Abstract: By combining a special dispersion map that has nearly constant path-average dispersion, a hybrid amplification scheme involving backward-pumped Raman gain, and sliding-frequency guiding filters, we have demonstrated massive wavelength-division multiplexing at 10 Gbits/s per channel, error free (bit-error rate, ≤1×10-9 for all channels), without the use of forward error correction, over greater than 9000 km, using dispersion-managed solitons. The number of channels (27) was limited only by a temporary lack of amplifier power and gain flatness. Terabit capacities are to be expected in the near future.

TL;DR: Space-division multiplexing (SDM) is bound to become an important optical networking technology over the next decade because of its importance in reducing cost, footprint, and energy consumption, and integration-induced crosstalk.
Abstract: Optical networks have economically enabled an unabated exponential traffic growth over the past decades, with commercial wavelength-division multiplexed (WDM) systems carrying over 20 Tb/s of traffic per fiber, closely approaching the nonlinear Shannon limit. Looking at all physical dimensions available for further capacity scaling, it becomes clear that tapping into the spatial dimension is the only long-term scalable solution to overcome the looming optical network capacity crunch. As such, space-division multiplexing (SDM) is bound to become an important optical networking technology over the next decade. Integration of SDM components will be key in reducing cost, footprint, and energy consumption, while integration-induced crosstalk may be compensated through the use of digital signal processing similar to that of vectoring used in digital subscriber lines (DSL) or multiple-input-multiple-output (MIMO) techniques used in long-term evolution (LTE) wireless systems.
