Компания Huawei разработала концепт магистральной передачи 400G DWDM


Технологии передачи данных не стоят на месте, крупные и не очень компании продолжают предлагать новые решения в этой области. Так, компания Huawei на днях представила свой проект магистральной передачи 400G DWDM. По словам разработчиков, это первая подобная система в мире. Данная технология позволяет передавать данные со скоростью вплоть до 20 Тбит/с по одному оптоволокну (в пределах С-диапазона) на расстояние вплоть до 1000 км без необходимости внедрения электрической регенерации. Это позволяет вывести технологию за рамки стандарта 100G.

Фактически, говорят разработчики, 400G DWDM представляет собой систему DWDM следующего поколения. Такую систему можно будет применять в сфере создания ультраширокополостных сетей с так называемым повсеместным охватом. Система была разработана благодаря сочетанию сразу нескольких современных наработок. Во-первых, это новейший метод когерентного приема. Во-вторых, это новый алгоритм SD-FEC. В-третьих, это использование производительных оптических модулей.

Компания смогла показать подключение услуг 400GE и 4×100GE, плюс новую наработку — технологию OTN на уровне OTU-5.

«Передовое решение 400G DWDM отвечает требованиям операторов по увеличению полосы пропускания сети в будущем. Компания разрабатывает инновационные решения, помогая заказчикам в достижении их бизнес-целей. Мы рады, что даем операторам возможность успешно решить задачу увеличения полосы пропускания», — сообщил Кристиан Чуа (Christian Chua), президент направления оборудования для транспортных сетей компании Huawei.

    Huawei вообще молодцы. С ними нельзя не считаться теперь. Не скажу, что они активнее циски двигают современный телеком вперёд, но заслуги их огромны.
    Ну а внедрения 400 Gb в жизнь, в реальные сети можно ждать лет через 5-7, потому что даже 100G, которые ещё не начали поставлять во большому счёту стоят каких-то баснословных денег.

    The summer temperatures on Nevis are also good, being only 3 F higher than the winter, averaging 82 F (27.8 C). Winds are usually less strong in the summertime, except of course during tropical storms or hurricanes. Because there is less wind, the ocean water is calmer and slightly warmer, so summer is ideal for diving. And because the climate on Nevis never gets very hot or very humid, summer is also a good time for people from the southern parts of the USA to leave behind all that stifling heat and humidity. Nevis beaches are never crowded, and both airline rates and hotel rates are cheaper in the summer.

    Hooded garments weren’t always shrouded in nefarious intent, though their function of obscuring the wearer goes back to the Middle Ages, when monks and scholars wore hoods to shield their faces. Hoods served as protective items for farmworkers into the 19th century, worn as part of jackets or overcoats, said Mark Evan Blackman, assistant professor of apparel design at New York’s Fashion Institute of Technology.

    It doesn’t hold true with regard to knock offs. There’s an adage that you receive what you pay for. This is completely true with brand name apparel as well as accessories. These are generally a little overvalued. No one would confuse Oakley having a knock off if the two were observed side by side.

    Shared reading is a critically important factor in a young child’s reading development. This was recognized and reflected in the National Curriculum, by means of the new National Literacy Hour. This has made a huge impact on the way literacy is taught in our schools. The first 15 minutes of every Literacy Hour is now spent with shared reading, which includes the whole class. During this literacy hour it became apparent that every child, including the less confident readers would be highly motivated to participate with the reading itself and improve as a result. Through targeted questioning and interaction of the text an encouragement for participation unveils and a child subsequently improves within their reading skills as well as in social skills and confidence. Another advantage found from using this technique was the offering of a fluent reading pace as well as the fundamental benefits of practice and reinforcement that occurred during this method.

    Re » Carmen Basilio: Middleweight boxing champion beat Robinson ,» Obituary, Nov. 9 So sorry to learn of Carmen Basilio’s passing. He was a true sportsman and gentleman. Thanks for publishing a real sports photo. Basilio and Sugar Ray in the middle of the ring it doesn’t get any better than that. The skill, effort and dedication to the craft is palpable. Over the last few years, so many «sports» photos depict «celebrations» and other non athletic activities. Tuesday at Mount Sinai Memorial Park and Mortuary in the Hollywood Hills. I can only poorly paraphrase. Art had been knocked to the canvas, one of many times, at the Olympic Auditorium and the referee needed to see if the bout should be continued. Standing over Aragon, the ref asked his name and the Golden Boy replied correctly. He asked if he knew where he was and Art was indeed aware he was at the Olympic. Through sunglasses in the dark office, he stares through the window at passers by on Victory Boulevard. The phone rings. «HelloAragon,» he mumbles. He listens briefly, then mumbles again, «Sorry, no collect calls,» and abruptly hangs up. A visitor asks who it was. «Some guy in jail,» he says. I am a boxing fan from way back and very well remember the days of the Art Aragon fights. I have seen him take some merciless beatings and keep coming back for more. He always gave his fans their money’s worth. Jim Murray deserves great praise from boxing fans of the Art Aragon days. MURRAY KOPELLE Culver CityNames in the News

    Before the dust had settled, I had signed two confessions (haltingly written in kanji by the oldest, slowest member of the force), lost my composure even more times and satisfied my questioners curiosity about my sunglasses (in contrast to many fashionable Japanese men, I wear them during the day and take them off at night). I was finally free to go, but not before the senior officer attempted to shake my hand, as though the last several hours had been a grand old time that we had all enjoyed immensely. I wouldnt be surprised if he has one of my signed confessions on his office wall to this day.

    Age related macular degeneration (AMD): AMD is one of the leading causes of new blindness in the United States and although scientists are still investigating the relationship, it is known that the retina is extremely susceptible to photochemical damage from continuous light exposure and regional studies show that people that have more exposure in the sun also have a higher incidence of macular degeneration. More recently, short wavelength light (blue) has been getting more attention as it is found to cause significant stress to the cells in the macula so sun protection in the form of sunglasses for people with risk of developing this disease is extremely important.

    Obviously, more crimes are committed at night than in the day, presumably for the sheer fact that it’s easier to get away. But oddly enough, even otherwise law abiding people make moral choices based on how bright the lighting is regardless of whether other people can still see them. Dim light simply makes people less honest and more likely to cheat.

    I found what I wanted and headed toward the checkout stand. In front of me was a little lady, probably about 80 years old, examining a display of eyeglasses. These were not sunglasses. They had clear lenses like you’d want to use to read small print or do needlework. This lady tried on two or three pairs of glasses, each time carefully checking the focus by looking at a card on the display case that had different sizes of print. Obviously she was very eager to select the perfect pair.
