networks of fiber communications 中文意思是什麼

networks of fiber communications 解釋
光纖通信網路
  1. The advent of vlsi technology and fiber optics material science has enabled us to design massively parallel processing computer systems and fast and complicated communications networks

    超大規模集成電路技術和光纖材料科學的發展使我們有能力設計大型并行處理計算機系統和快速、復雜的通信網路。
  2. Optical code division multiple access ( ocdma ) is a communication mode which introduces the code division multiple access ( cdma ) technology into optical fiber communication system. besides providing asynchronous communications access, ocdma system has many advantages, such as high capacity, security against interception, suppression of narrow band disturbances, capability in forming variable bit rate networks and multi - rate networks. it implies a great challenge for the development of future communication networks, especially all optical networks

    光碼分多址（ ocdma ）是將碼分多址（ cdma ）技術與大容量的光纖通信技術相結合的一種通信方式，其主要優點表現在如下幾個方面：允許多個用戶隨機地接入同一通道：可構成真正「透明」的全光通信網路；具有良好的安全性；允許可變速率或多速率傳輸，並可同時提供多種業務支持；具有優良好的抗干擾能力，並能夠充分地利用石英光纖的可用帶寬。
  3. Infrastructure / communications : poor. however, the government is attempting to strengthen telecom infrastructure and build fiber - optic networks in city centers of software activity, as well as providing uninterrupted power supply

    基礎設施/通信：差。不過，政府正在加強電信基礎設施和在軟體業發達的中心城市建設光纖網路，同時提供無中斷地電力供應。
