4G LTE 微細胞/皮細胞間通訊之關鍵零組件與系統之開發( II )

Abstract

隨著雲端運算和智慧型手機的興起，人類對有線、無線網路頻寬的須求也以驚 人的速度在成長。也因為這樣，在資料中心 (Data center)的網路匯流頻寬，和其 建築物本身之規模，電功耗量也是不斷的增加。然而要連接如此龐大的資料量， 使用傳統的電纜線連接在頻寬、距離、和電功耗量上，完全無法和使用光電元 件和光纖的主動光纜線 (Active optical cable; AOC) 技術競爭。光連接技術的興 起也顛覆了傳統光纖通信的概念。和傳統光纖通信的市場相比，主動光纜線將 會更接近消費性電子市場，而且其對功耗的須求更為嚴格。超低功耗才能必免 伺服器過熱並增加排線密度。，我們也預期其將成為光通信市場自2000 年泡沫 化後，真正再起的最後希望。 在目前市面上，主要的主動光纜線集中在4

Due to the blooms in the market of cloud computing and smart phone, the demanding of wired and wireless bandwidth for communication tremendously increases. This truth thus strongly boosts up the total data flow rate in the data center, its scale of area, and the required DC electrical power consumption. Compared with using the traditional electrical cable to connect such huge amount of data flow rate, using the active optical cable (AOC) exhibits a wider bandwidth, a loner transmission distance, and is more power-saving. In addition, compared with the market of traditional long-reach fiber communication, the demanding of AOC is more close to the consumer electronic market and it needs much lower power consumption to avoid the heating in server and increase the bus-line density. We can also expect that the scale of AOC market is much larger than that of the traditional fiber communication. Now, the major product of AOC is focusing on the spec. of 4
