Description

Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.

As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics:

- The transmitter and receiver for phase-modulated coherent lightwave systems

- Method for performance analysis of phase-modulated optical signals

- Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects

- Wavelength-division-multiplexed direct-detection DPSK signals

- Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal.

Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field.

描述

光纖通信系統已經改變了我們的電信基礎設施 - 目前幾乎所有的電話、手機和互聯網通信都必須通過某種形式的光纖進行。在這些傳輸系統中,光信號的相位和頻率都不攜帶信息 - 只有信號的強度被使用。為了在單個光載波中傳輸更多信息,必須探索光載波的相位。

因此,對於長距離光纖通信系統中的直接檢測DPSK信號,相位調變光通信重新引起了興趣。當使用光放大器來保持光纖鏈路中的某一信號水平時,系統受到放大器噪聲和光纖非線性的限制。《相位調變光通信系統》對這個新興的領域進行了調查,涵蓋了以下主題:

- 相位調變相干光波系統的發射機和接收機
- 相位調變光信號性能分析方法
- 受非線性相位噪聲和信道內效應影響的直接檢測DPSK信號
- 波長分組多路復用的直接檢測DPSK信號
- 多級相位調變光信號,如四相DQPSK信號。

研究生、專業工程師和研究人員都將從這本光通信領域中重要主題的最新研究中受益。
