Fiber Optic Systems for Telecommunications

A text that sheds much-needed light on one of telecommunication’s brightest technologies

Fiber optics has assumed a dominant place among the available technologies to slake the ever-growing worldwide thirst for bandwidth. As miles and miles of optical fiber cable is being buried underground and under the sea, the demand for those capable of designing and installing fiber-optic systems has also grown. This book gathers all the essential information needed by the network architects, engineers, and craftspeople who plan, install, and maintain fiber-optic systems.

Requiring only a basic math and physics background, Fiber-Optic Systems for Telecommunications acts as both a tutorial and practical reference on both theory and practical applications.

It discusses:

• Loss-limited and dispersion-limited fiber links
• Optical networking
• Availability and survivability of fiber-optic networks
• Dense wave-division multiplexing (DWDM)
• Light transmission impairments, including Brillioun scattering, Raman scattering, four-wave mixing, polarization mode dispersion (PMD), and other non-linear effects
• Hybrid fiber-coax CATV networks
• Fiber-optic link budgets and tradeoffs

The text stresses design methods for achieving advanced performance on fiber-optic systems inside cost-effective limits. At the same time, a good dose of practical application is provided to the reader. For example, there is an extensive section on the application of an OTDR (optical time domain reflectometer) for performance measurement and troubleshooting of optical systems.

The book examines the maximum capacity of high-quality single-mode fiber. Here, the ITU has made some major contributions in this arena in their G.650 and G.950 recommendations. The author describes the ITU "grid" or wavelength assignment chart for the 1550 nm band. How close can these light carriers be placed before serious performance degradation occurs? He describes ultimate bit rate capacity in this band alone in the hundred of terabits reaching a final bit rate capacity possibly in the low thousands of terabits per second. The author communicates the excitement of such research in his writing.

這本書提供了對於電信領域中最重要的技術之一——光纖通訊技術的深入解析。

光纖通訊技術已經成為滿足全球不斷增長的頻寬需求的主要技術之一。隨著越來越多的光纖電纜被埋設在地下和海底，對於設計和安裝光纖系統的能力也越來越受到需求的推動。這本書匯集了所有網絡架構師、工程師和技術人員所需的基本信息，他們負責規劃、安裝和維護光纖系統。

本書只需要基本的數學和物理背景知識，既是一本教程，也是一本關於理論和實際應用的實用參考書。它討論了以下內容：

- 限制於損耗和色散的光纖鏈路
- 光纖網絡
- 光纖網絡的可用性和可靠性
- 密集波分多工（DWDM）
- 光傳輸的影響，包括布里淚散射、拉曼散射、四波混頻、偏振模色散（PMD）和其他非線性效應
- 混合光纖同軸電視（CATV）網絡
- 光纖鏈路預算和權衡

本書強調在成本效益範圍內實現先進性能的設計方法。同時，本書還提供了大量的實際應用案例。例如，書中詳細介紹了光時域反射儀（OTDR）在光學系統性能測量和故障排除中的應用。

本書還探討了高品質單模光纖的最大容量。在這方面，國際電信聯盟（ITU）在其G.650和G.950建議中做出了重大貢獻。作者描述了ITU在1550納米波段的“網格”或波長分配圖。在嚴重影響性能的情況下，這些光載體可以放置得多接近？作者描述了僅在這個波段內的最終位元速率容量可能達到數百太比特，最終位元速率容量可能達到每秒數千太比特。作者通過他的寫作傳達了這項研究的激動人心之處。
