中文摘要 | 本文報告兩種主要之光傳送技術:分波多工(Wavelength Division Multiplexing, WDM) 及光時域多工(Optical Time division Multiplexing, OTDM)。WDM技術已商用化且歐美國家已 在骨幹網路中建置WDM系統,以提昇光纖之傳輸容量;因一方面,OTDM技術雖未成熟, 但研究指出其與WDM技術為互補且須混合使用,才能有效利用現有光纖設施。由於光網路 時代即將來臨,本文闡述光網路設備之特性及ITU-T正在研擬之光網接標準,並指出仍在考 慮與爭論中之議題。最後,本文提出光傳送網路之功能架構及管理功能,以掌握未來網管系 統之設計觀念。 |
英文摘要 | This paper discuss two main optical transport technologies: Wavelength Division Multiplexing (WDM) and Optical Time Division Multiplexing (OTDM). The WDM has been widely commercialized and applied to the backbone network in Europe and North America for increasing the transmission capacity of the optical fibers. OTDM, on the other had, is currently viewed as a longer-term solution because it relies on different an much less mature technologies. The studies show the WDM and OTDM are complimentary technologies which must be used together for most efficiently utilizing the existing fiber plant. The advanced optical technologies have announced the coming of optical networking. The paper describes the features of the optical network elements and the current state of optical networking standards developed by ITU-T, with emphasis on major issues under considerations. Finally, this paper presents the functional modeling and the management function of optical transport network to understand the design concepts of future network management system. |
