TL;DR: An optical backplane ecosystem is described and demonstrated that is capable of multi-Tb/s bandwidth and is based on embedded polymer waveguides, passive Optical backplane connectors, and midboard optical transceivers with bandwidth up to 28 Gb/S per lane.
Abstract: An optical backplane ecosystem is described and demonstrated that is capable of multi-Tb/s bandwidth and is based on embedded polymer waveguides, passive optical backplane connectors, and midboard optical transceivers with bandwidth up to 28 Gb/s per lane. These systems provide the highest bandwidth-density, lowest power consumption, while maintaining the signal integrity. Ecosystems built around this architecture will provide the bandwidth-density required for next generation fabric interconnect for storage, switching, and routing applications in future high capacity generations of Data Centers and HPC systems. To demonstrate the applicability of this technology, it was used to provide embedded optical connectivity within a functional data storage enclosure.

TL;DR: In this article, the authors proposed a novel fiber link loss monitoring method for a WDM passive optical network based on the optical signal comparison between a reference amplified spontaneous emission signal and its reflection from an optical reflector.
Abstract: We propose and demonstrate a novel fiber link loss monitoring method for a wavelength-division-multiplexed (WDM) passive optical network. This method is based on the optical signal comparison between a reference amplified spontaneous emission signal and its reflection from an optical reflector. Therefore, we can calculate the link loss exactly and also measure the characteristics of upstream optical signals without suspending the in-service channels. Since this scheme does not use narrow-band wavelength-dependent components such as fiber Bragg gratings, it is cost-effective in implementation and maintenance within a real optical network. We experimentally demonstrate that the link quality of upstream signals as well as fiber link faults on all WDM channels can be monitored in real time

10 Oct 2011TL;DR: In this article, an optical transport network based on multimode/multicore fibers includes a mode-multiplexer to multiplex independent data streams from one or more transmitters, a multimode erbium-doped fiber amplifier (MM EDFA) to compensate for MMF loss, and a multi-modal optical add-drop multiplexer (MM OADM) to add and/or drop multimode channels in multimode networks.
Abstract: An optical transport network based on multimode/multicore fibers includes a mode-multiplexer to multiplex independent data streams from one or more transmitters; a multimode erbium-doped fiber amplifier (MM EDFA) to compensate for MMF loss; a multimode optical add-drop multiplexer (MM OADM) to add and/or drop multimode channels in multimode networks; a multimode optical cross-connect; and a mode-demultiplexer to separate various mode streams to one or more receivers.

TL;DR: This paper is a tutorial reviewing research and development performed over the last few years to extend the reach of passive optical networks using technology such as optical amplifiers.
Abstract: We discuss recent progress in the development of optically amplified, long reach passive optical networks, which aim to significantly reduce network complexity and cost by integrating metro and access into a single, all-optical communication system.

TL;DR: Some basic transmission considerations relating to system operation over wide optical bandwidths for both local and longer distance networks are reviewed, and the present status of experimental optical networks and the components they use are discussed.
Abstract: Optical network technology will soon allow wavelength-multiplexed optical channels to be carried to multiple terminals, giving rise to new broadband network architectures and protocols. Two stages of evolution are anticipated, with transmission-only structures appearing first and networks with optical switching appearing later. Some basic transmission considerations relating to system operation over wide optical bandwidths for both local and longer distance networks are reviewed, and the present status of experimental optical networks and the components they use are discussed. >
