    作為介質共享的樹形網路， apon需要介質訪問控制協議（ mac ）協調各終端對上行通道的訪問，避免沖突。
  4. We focus on study and design of medium access control ( mac ) protocol used in apon. the mac protocol must have excellent performance to certify as small transfer delay ( td ) and cell delay variation ( cdv ) as possible to meet all kinds of services besides no collision between cells

    我們在本論文研究的重點就是設計一個媒質接入控制協議，使得用戶上行信元有序到達olt而不發生碰撞，同時保證各業務所要求的傳輸時延（ td ）和信元時延抖動（ cdv ） 。
  5. In all kinds of alternatives, atm based passive optical network ( apon ) has the most promising prospect, which supports broadband service and service transparency. in addition, it combines the advantages of multi - service and multi - bit rate capabilities of atm and the advantages of wide bandwidth and low cost of pon

    在各種可能的接入方案中，長遠看基於atm的無源光接入網（ apon ）是最具市場潛力的接入方案，它支持寬帶接入業務，業務透明，結合了atm的多業務、多比特率技術和無源光接入網的寬帶寬、低成本優勢。
  6. The network architecture of point - to - multipoint and the working mode of tdma ( time division multiple address ) of apon make the upstream signal works in burst mode

    Apon的這種點到多點的網路結構和時分多址的工作方式決定了其上行信號是以「突發」方式工作的。
  7. The method of random access is rather simple and easy to expand, but it cannot satisfy the rigorous delay and throughput requirements of telecommunication network. so it is not available for apon

    隨機接入控制方法雖然具有簡單和易於擴展的特點，但是無法滿足電信級的時延和吞吐量要求，因而不適用於apon系統。
  8. Beacause apon ’ s efficiency is low and epon could not provide quality assurance for real - time services, network inspection, operation management and network control, gpon was proposed by fsan in september 2002, which can provide gigabit speed, high efficiency, transparent transmission of multi - services and specific quality of service. at present, the gpon standards, g. 984. 1, g. 984. 2, g. 984. 3 and g. 984. 4, have been established by itu - t

    Fsan組織考慮到apon的低效率和epon的無法對傳送實時業務提供質量保證、缺乏電信級的網路監測和業務管理等方面的不足，於2002年9月提出了具有gbit / s級的高速率、高效率，支持多業務透明傳輸，能夠提供明確的服務質量保證和服務級別，具有電信級的網路監測和業務管理能力的光纖接入網gpon 。
  9. Apon is a passive optical network where atm is adopted to transmit broadband and narrowband cells via the sdh frame structure. the service node interface is stm - n. the statistical multiplexing feature of atm enables a concentrated transmission of broadband services in apon

    Apon是在無源光網路中採用atm傳送技術，利用sdh幀結構傳送各種寬帶和窄帶業務的信元，業務節點介面採用stm - n介面。
  10. Presently, the apon system adopts tdma as the access mode on the uplink. it requires not too much in terms of optical performance, but it requires more complex electronic equipment ( e. g., complex synchronized timing, ranging and delay control technolgies ) to avoid the collision of uplink information packets

    目前apon系統在上行通道中採用時分多址的接入方式，它對光性能方面的要求不高，但它要求更復雜的電子設備，如要求復雜的同步定時、測距和延時控制技術，以避免上行信息分組產生碰撞。
  11. Firstly, apon needs to solve the ranging problem

    首先， apon要解決的問題是測距問題。
  12. Passive optical network apon

    無源光網路
  13. Chapter 2 analyzes the principle of the apon system and the key technologies used in it

    第2章深入研究了apon系統的原理及關鍵技術。
  14. Secondly, apon needs to address the fast synchronization of burst cells on the uplink

  15. The design of burst mode receiver should take into accounts of some technical questions in apon

    突發式接收模塊的設計應考慮apon系統中的若干技術問題而設計。
  16. Due to its high - splitting and high - delay, mac protocols for apon are not available for superpon

    由於其多用戶和大時延的特點， apon的mac協議並不適用於superpon 。
  17. What is more, apon also needs to address the key technology relating to the sending and receiving of bursts

    另外， apon還需要解決突發發送和接收的技術關鍵問題。
