And this corresponds to the 40G 科路network market burgeoned. From the 這們current market situation, Extreme, and 飛照Dell can be said to account for t訊筆he day, but other 雜上vendors release and no later. C習農isco, Juniper Networks, A冷好lcatel-Lucent, H3C, 錢技Rui Jie manufacturers are grad上話ually released products, the em火文erging vendors Arista and 日亮Mellanox solutions 舊船are also distinctive fea業相tures.

Deployment of 40G: those thi房森ngs you have to 紙女consider
The 40G network devices東習 has been presen放森ted, but the actual selection an還鐘d deployment process, you want to buil書地d a network need to consider a的畫 lot.

Another exa微議mple, should also be considered in the 黑土actual deployment pr站著ocess supporting systems, wiring, p短火ower supply and c雨空abinet with which to弟用 match.

In fact, "The most important fa黑外ctor is the actual user network bus林的iness needs, select the appropriate 妹樹interface bandwidth according 這大to the current traffic situation. Shou藍員ld give full con月音sideration to the future of技北 network upgrading明笑 and expansion of capacity."工又 Lu Guoqiang answer from the pre做來sent and future perspective explai理南ned. What means as defined criteri事山a?
"Generally, we see the Gigabit port 湖數density, enhance the美腦 access layer Gigabi就謝t port density, the自業 core layer 40G connection is the 資慢inevitable trend of dev高火elopment of the data center." The 西雜Ruijie Co., Ltd. Produ公工ct Marketing data 妹河center product manager Jiang wave s男區ay. Arista interna舞黃tional sales vice presid謝如ent Mark FOSS from內票 several aspects gives a more d外輛etailed answer: "First 科遠of all, depending on the dema鄉裡nd for network bandwi西機dth; Second, we m理雪ust consider the actual networ空唱king equipment interconnecti知坐on distance less than 150 meters 如也consider 40GbE/100GbE interconnect子購 distance is more than 150日讀 meters, it is sti笑睡ll mainly consider ad也廠opting 10GbE; once again to 車煙consider the flexibility of the 離司wiring for easy wir了微ing, simple, we can consider the 志間10, 40 or 100GbE, we must al公離so consider interconnect t藍區wisted-pair, dual coaxial到弟 cable or optical fiber. 樂藍To connect to the serv一服er using existing twisted-pair ca用中bling system, can consid動請er adopting 10GbE fi月見rst.

Mentioned in M報雨arks summary wiring is not the same a劇玩s the recommendations are given老刀 for different distances and flexib問月ility requirement事亮s, which is what causes 票們it? Wiring the field of p能西rofessional manufacturer些我s have the final say. "火大10G Ethernet fiber and copper t黑場ransmission standard has been rel他著eased, but 40G Ethernet tran林看smission purposes on西學ly fiber standard copper s頻票tandard." Simon Technical 志行Manager Chen Yuton報算g said. From the per男中spective of the dev厭是elopment of the wiring, in gene見歌ral, the copper standard is always b冷城ehind the application o做店f standards and fiber standards. 10G h這唱istory is the c離服ase. International Organization for wi厭線ring TIA and ISO have s筆鐘et up a Working Group on copper st到要andard. The name小花 of the TIA TIA 568-C.2-1, IS朋舞O name is ISO 11801-99-X, TIA standar冷厭d mentioned is 100 ohms to suppo的得rt the next generation of cabling s師金pecifications, but d有頻oes not explicitly 40G or 100門白G, and ISO clear in 遠森40G transmission areas. Men鐵術tioned several times in the previou房謝s QSFP + is actually a電公 short distance transmission. 公身In general, it is us光林ed to connect the ToR switches鐘呢, distance is no more than one cab水會inet. QSFP + and SFP + just to make u有個p the twisted pair supports v用店acuum. Chen Yutong think so. 鄉生Of course, some peo都友ple think that the fut雜煙ure QSFP + and SFP + will replace the雨還 existing twisted-pair wiring. QSFP + a上作nd SFP + shipping校老 gradually decreased,作書 and twisted pair gradual increase in草那 2013, the QSFP + and SFP +頻國 and 10GBase-T will be basically來謝 the same as, long ago, Inte文畫l released a forecast.
Since the wiring that is the cas匠日e, the user should make a 船外choice? Short distance can choose QSF技森P + and SFP +, can be considered船紅 long-distance optical fiber. Stand車計ard supports 100 m multimode fiber 大笑OM3, OM4 standard is 1有門50 meters, you will not encounte我低r single-mode fiber transmissio日是n distance. "Chen Yutong such 腦筆a suggestion.
