Analyse the Potential Opportunities in Future Optical Communications Systems and in Viable Photonic Integration Processes.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/research/5ccec3/future_optical_com) has announced the addition of the "Future Optical Communications Optical communications The transmission of speech, data, video, and other information by means of the visible and the infrared portion of the electromagnetic spectrum. Systems" report to their offering. The communication equipment industry has survived the bubble and returned to health. Video is an important revenue generating platform for both cable and telecom service providers and will also impact heavily on the traffic management issue. The near term needs can be met by improving the performance of the present set of optoelectronics devices such as distributed feedback (DFB DFB acronym for dark, firm, dry meat. Called also dark cutting beef. ) laser arrays, tunable lasers, fast and complex modulators, arrayed waveguide gratings Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing a large number of wavelengths into a single optical fiber, thereby increasing the transmission capacity of (AWG (American Wiring Gauge) A U.S. measurement standard of the diameter of non-ferrous wire, which includes copper and aluminum. In general, the thicker the wire, the greater the current-carrying capacity and the longer the distance it can span. ), and reconfigurable optical add drop multiplexers (ROADM ROADM Reconfigurable Optical Add/Drop Multiplexer ROADM Reconfigurable Add Drop Multiplexing ). The use of electronic and optical compensation techniques and new signal encoding formats have extended the reach of directly modulated mod·u·late v. mod·u·lat·ed, mod·u·lat·ing, mod·u·lates v.tr. 1.

Low-cost optical-electrical-optical (OEO (Optical in Electrical processing Optical out) Refers to network devices that convert photonic transmission signals to electronic signals in order to analyze the traffic content for switching purposes. It then reconverts the signal to light for output. Contrast with OOO. ) conversions allow an alternate approach to network evolution. Coherent transmission eliminates signal impairments but presents multiple challenges. In the fiber to the home/curb environment, the potential for truly photonic integrated circuits A Photonic Integrated Circuit (PIC) is a device that integrates multiple photonic functions and as such is analogous to an Electronic Integrated Circuit. However the major difference between the two being that a photonic integrated circuit provides functionality for information to reduce assembly costs and simplify functionality is slowly becoming a reality. 100 Gb/s transport in the core is achievable to accommodate the Internet growth forecast in the short-term. However, there is no such optoelectronics device base for a terabit/s network (which we now refer to as 'terabit photonics'). We need to advocate the initiation of comprehensive R&D efforts to generate new device and system concepts over the next decade. In fact, we now expect the demand for high speed bandwidth to exceed our capacity significantly over the next decade. This implies that network-choking will be an ongoing problem similar to 'traffic jams' in major cities today. In addition, components suppliers need to furnish devices and/or modules with high per-formances and more functions at low cost to meet future requirements. This may mean that some device/module manufacturers will turn to the consumer market for volume scaling. The threat of display-choking (communicating in and out of the display with a remote processor) is emerging on the radar screens of many television manufacturers as they progress towards high-definition television high-definition television (HDTV) Any system producing significantly greater picture resolution than that of the ordinary 525-line (625-line in Europe) television screen. Conventional television transmits signals in analog form. (HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates ). By providing the consumer with an active cable solution with embedded optics, it may be possible to reduce 10 Gbps technology cost through volume production to ease the issues of display-choking. The conclusion of this forum is to pursue photonics integration. Only viable photonics integration processes can achieve this goal and keep up with future needs of communication systems beyond terabit/s. We must promote the adoption of viable integration processes to sustain progress. We also believe that photonics integration will positively impact the volume consumer market for interconnects in addition to the network edge.
