2.5.1损耗测量
光纤损耗测量有两种基本方法：一种是测量通过光纤的 传输光功率，称剪断法和插入法；另一种是测量光纤的后向 散射光功率，称后向散射法。
1. 光纤损耗系数由式(2.61a)确定， 即
a 10 lg p1 (dB / Km) L p2
式中，L为被测光纤长度(km)，P1和P2分别为输入光功率 和输出光功率(mW或W)。
本节介绍光纤损耗、带宽(色散)和截止波长的测量原理和 测量方法。这些特性参数的测量的共同的特点是用特定波长 的光通过光纤，然后测出输出端相对于输入端的光功率或幅 度、相位等物理量的变化，再经过相应的数据处理而实现的。 测量系统一般包括发射光源、注入装置和接收与数据处理设 备。测量仪器要求稳定、可靠，并有足够的精确度。测量的 详细技术规范由国际标准(例如ITU - T，即原CCITT G650)或 国家标准确定。

光纤主要参数的英文缩写
光纤主要参数的英文缩写Fiber optic cables are essential components of modern telecommunications networks, and understanding their key parameters is crucial for effective network design and maintenance. These parameters are often represented by various acronyms and abbreviations in the industry. In this article, we will explore some of the main parameters of fiber optic cables and their corresponding English abbreviations.1. Attenuation (Attn): This parameter measures the reduction in signal strength as light travels through the fiber. It is typically expressed in decibels per kilometer (dB/km). A higher attenuation value indicates a faster loss of signal strength, which can limit the transmission distance or require the use of optical amplifiers.2. Bandwidth: This refers to the range of frequencies or wavelengths that can be transmitted effectively through the fiber. Bandwidth is often specified in gigahertz (GHz)or terahertz (THz). A wider bandwidth allows for higher data transmission rates.3. Modal Dispersion (MD): This is a parameter specific to multi-mode fiber (MMF) that describes the spreading of light waves within the fiber core due to different propagation modes. Modal dispersion can limit the bandwidth and transmission distance of MMF.4. Chromatic Dispersion (CD): This parameter characterizes the change in propagation velocity of light waves with different wavelengths within the fiber. Chromatic dispersion can cause pulse broadening and intersymbol interference, limiting the transmission capacity and distance.5. Numerical Aperture (NA): This parameter is related to the acceptance angle of light into the fiber core. It is a measure of the fiber's ability to capture and transmit light. A higher numerical aperture allows for a wider range of angles, but it also increases the potential for optical losses and noise.6. Effective Area (Aeff): This parameter describes the cross-sectional area of the fiber core that is effectively used for light transmission. It is important for understanding the power handling capabilities of the fiber and for mitigating nonlinear optical effects such as self-phase modulation.7. Mode Field Diameter (MFD): This is a measure of the diameter of the light beam within the fiber core. It is particularly relevant for multi-mode fibers, wheredifferent modes have different propagation characteristics. The mode field diameter affects the coupling efficiency between the fiber and other optical components.In addition to these parameters, there are several other important considerations in fiber optic cables, including their mechanical properties (such as tensile strength and flexibility), environmental resistance (to factors like temperature and humidity), and compatibility with various connector types.Understanding these parameters and their abbreviations is crucial for effectively evaluating and selecting fiber optic cables for specific applications. It also helps in troubleshooting network issues and optimizing system performance. With the continued growth of data transmission demands, the importance of fiber optic cables and their parameters will continue to increase.。

光纤通信技术 英文教材
光纤通信技术英文教材English:Fiber optic communication technology is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. This technology provides high-speed data transmission and is widely used in telecommunications, internet, and networking. The core of a fiber optic cable is made of a very thin strand of glass or plastic that is capable of transmitting light waves over long distances with minimal loss of signal strength. The information is encoded into the light pulses and then decoded at the receiving end, allowing for secure and reliable communication. Compared to traditional copper wire communication, fiber optic technology offers higher bandwidth, greater resistance to electromagnetic interference, and increased security due to the difficulty of tapping into the signal without detection.中文翻译:光纤通信技术是一种通过光纤发送光脉冲来实现信息在不同地点之间传输的方法。

The nature of light The fabrication of optical fibers The structure of an optical fiber The propagation principle of light along a fiber The transmission character of fiber
CONTENT
In 1815, Fresnel gived the correct explanation of diffraction. In 1864, Maxwell theorized that light waves must be electromagnetic in nature. The observation of polarization effects indicated that light wave are transverse. It is no different from a radio wave except that the wavelength is much shorter.

图2.12示出三种不同光源对应的rms脉冲展宽ζ和折射率分
布指数g的关系。由图可见，rms脉冲展宽ζ随光源谱线宽度ζ 增大而增大，并在很大程度上取决于折射率分布指数g。 当 g=g0时，ζ达到最小值。g的最佳值g0=2+ε，取决于光纤结构 参数和材料的波长特性。当用分布反馈激光器时，最小ζ约为 0.018 ns，相应的带宽达到10 GHz· km。 3. 单模光纤的色散 色度色散 理想单模光纤没有模式色散，只有材料色散
其rms谱线宽度为ζλ，每个传输模式具有相同的功率， 经复杂 的计算，得到长度为L的多模光纤rms脉冲展宽为

光纤带宽的概念来源于线性非时变系统的一般理论。如果 光纤可以按线性系统处理，其输入光脉冲功率Pi(t)和输出光脉 冲功率Po(t)的一般关系为 Po(t)=
h(t t) pi (t)dt
当输入光脉冲Pi(t)=δ(t)时，输出光脉冲Po(t)=h(t)，式中δ(t)
为δ函数，h(t)称为光纤冲击响应。 冲击响应h(t)的傅里叶( Fourier)变换为 H(f)=
