“…However, Rayleigh backscattering (RB) will be produced by the distributed optical carrier when single distribution/drop fiber is used. Different solutions to mitigate the RB noise, including: using carrier suppressed single sideband (CS-SSB) modulation at the RONU [5,6], using carrier suppressed subcarrier-amplitude modulated phase shift keying (CSS-AMPSK) [7], using phase-modulation induced spectral broadening [8] or using wavelength splitting [9] could be employed.…”

“…However, this condition dramatically varies because of the Rayleigh backscattering (RB) effect which is a common network topology in optical access which transmits up/down stream through a single fibre loopback link, especially in uplink transmission [10][11][12][13][14][15][16][17]. Consequently, the OFDMA-PON transmitters should estimate their CSI frequently with respect to catch up with fast-changing channel responses [18] and as a result it generates too much redundancy.…”

The authors have proposed and experimentally demonstrated a novel slow adaptive orthogonal frequency division multiple access (OFDMA)-based passive optical network (PON) uplink transmission scheme using a 1-GHz reflective semiconductor optical amplifier operating as an optical network unit (ONU) in combination with Rayleigh backscattering (RB) mitigation in a 20-km single fibre loopback link. This RB mitigation, which can dramatically stabilise the channel state information and enhance the total throughput so that the OFDMA-PON transmitters can operate in the slow adaptive concept and provides beyond 15-Gbit/s uplink transmission, is achieved by employing 10-MHz low-frequency dithering of an optical seed carrier cooperating with a gain-saturated semiconductor optical amplifier at an optical line terminal. In doing so, the proposed scheme could guarantee a 50% total throughput enhancement with a proof-of-concept multiple access scenario for two ONUs, compared to its counterpart that does not apply the RB mitigation technique.

“…Optical transparency is widely recognized to play a central role in next-generation optical networks and to offer significant networking advancements in terms of performance and cost [4]. The scalability of optical technology and the elimination of expensive opticalelectrical-optical (OEO) equipment is expected to significantly reduce the capital costs, whereas operational cost savings are expected to result from reduced power requirements and the flexibility of transparent service provisioning.…”

Abstract-Optical technologies are ubiquitous in telecommunications networks and systems, providing multiple wavelength channels of transport at 2.5 Gbit/sec to 40 Gbit/sec data rates over single fiber optic cables. Market pressures continue to drive the number of wavelength channels per fiber and the data rate per channel. This trend will continue for many years to come as electronic commerce grows and enterprises demand higher and reliable bandwidth over long distances. Electronic commerce, in turn, is driving the growth curves for single processor and multiprocessor performance in data base transaction and Web based servers. Ironically, the insatiable taste for enterprise network bandwidth, which has driven up the volume and pushed down the price of optical components for telecommunications, is simultaneously stressing computer system bandwidth increasing the need for new interconnection schemes and providing for the first time commercial opportunities for optical components in computer systems. The evolution of integrated circuit technology is causing system designs to move towards communication based architectures. We have presented the current tends of high performance system capacity of optical interconnection data transmission link in high performance optical communication and computing systems over wide range of the affecting parameters.
