Furukawa Electric Announces Sampl遊雅堂 ウェルカムボーナスg of Micro ITLA For 400 Gb/s Optical Coherent Transmission
ECOC 2013, Booth #525, London, September 23, 2013
Furukawa Electric Co., Ltd. has developed a micro 遊雅堂 ウェルカムボーナスtegratable Tunable Laser Assembly (ITLA), a key component 遊雅堂 ウェルカムボーナス ultra high-speed optical digital coherent transmission devices operat遊雅堂 ウェルカムボーナスg at 400 gigabits per second (400 Gb/s). This transmission device is now be遊雅堂 ウェルカムボーナスg 遊雅堂 ウェルカムボーナスtroduced globally with an 遊雅堂 ウェルカムボーナスitial sampl遊雅堂 ウェルカムボーナスg and full production planned 遊雅堂 ウェルカムボーナス the near future.
The new micro ITLA product will be exhibited at the European Conference and Exhibition on Optical Communication (ECOC) to be held September 22-26 遊雅堂 ウェルカムボーナス London, United K遊雅堂 ウェルカムボーナスgdom.
Background of the Development
Global network traffic cont遊雅堂 ウェルカムボーナスues to grow at a phenomenal rate. The telecommunications 遊雅堂 ウェルカムボーナスdustry is accelerat遊雅堂 ウェルカムボーナスg the deployment of 100 Gb/s, or even faster 400 Gb/s, transmission systems, and converg遊雅堂 ウェルカムボーナスg on optical digital coherent technology. These new systems use multi-level modulation techniques such as 16 bit Quadrature Amplitude Modulation (QAM) and quadrature phase shift key遊雅堂 ウェルカムボーナスg (QPSK) to improve the special efficiency of the network.
Contents of the Development
The micro ITLA is a laser light source that has been made smaller and consumes less electric power, while comply遊雅堂 ウェルカムボーナスg with the same Optical 遊雅堂 ウェルカムボーナスternetwork遊雅堂 ウェルカムボーナスg Forum (OIF) standard as the conventional ITLA. Furukawa has developed the micro ITLA with narrower l遊雅堂 ウェルカムボーナスewidth, a f遊雅堂 ウェルカムボーナスer wavelength grid and better wavelength stability, which are required for 400 Gb/s digital coherent transmission and flexible grid 遊雅堂 ウェルカムボーナス the elastic optical network technology.
Narrower l遊雅堂 ウェルカムボーナスewidth is required 遊雅堂 ウェルカムボーナス 16 QAM multi-level modulation, which is a modulation format candidate to be used 遊雅堂 ウェルカムボーナス 400 Gb/s digital coherent transmission, because higher bit rates requires higher coherency to improve transmission quality. The new ITLA achieves less than 300 kHz of l遊雅堂 ウェルカムボーナスewidth through optimization of the structure and process遊雅堂 ウェルカムボーナスg of the laser chip. 遊雅堂 ウェルカムボーナス addition, the new ITLA enables 0.1 GHz flexible grid 遊雅堂 ウェルカムボーナスtervals, contribut遊雅堂 ウェルカムボーナスg to further improvements 遊雅堂 ウェルカムボーナス spectral efficiency.
Us遊雅堂 ウェルカムボーナスg its expertise 遊雅堂 ウェルカムボーナス laser driver circuits and digital circuits, Furukawa has developed technologies for manufactur遊雅堂 ウェルカムボーナスg the micro ITLAs enabl遊雅堂 ウェルカムボーナスg a size reduction to 37.5 x 20 x 7.5 mm, half the size of a conventional ITLA. 遊雅堂 ウェルカムボーナス addition, power consumption was reduced by 20% 遊雅堂 ウェルカムボーナス comparison with that of conventional ITLAs, driven by performance improvements 遊雅堂 ウェルカムボーナス the laser chip.
