DP光纤看连接器的的作用

date:On November 24, 2017 Source:  

   说到使用光纤的连接器的作用是怎样的呢,有着怎样的作用?作为DP光纤延长器来看,连接器的作用原理是否一致,它的结构是怎样的,作为很多用户来说只是使用过,然而也没有真正的去了解光纤连接器的真正工作原理是怎样的。

Speaking of the role of the use of optical fiber connector is what, what kind of role? As a DP fiber extender, the principle of the connector is the same, its structure is like, as many users just used, but there is no real way to understand the true working principle of the optical fiber connector is what.


   光纤连接器随着光纤技术的不断成熟而逐渐发展。铜线连接器对AV系统信号丢失的影响一般不会很大,而光纤连接则不同,它对传输系统中的每个接口都会起着非常大的影响作用。让我们来看看光纤物理连接中所产生的一些问题,光纤传输设备自身可指令连接,但在有些情况下,大部分或几乎所有的光纤传输连接选择都是人为亲自进行。光纤线缆在信号传输过程中所丢失的信号量主要由所采用的光纤线缆的质量和类型所决定,每个连接端都会产生一定的信号丢失。

Optical fiber connector with the fiber technology continues to mature and gradually developed. The effects of copper connectors on AV system signal loss are generally not significant, whereas fiber optic connections are different and can have a significant impact on every interface in a transmission system. Let's take a look at some of the problems with fiber optic physical connections that can be instructed by fiber optic transmission equipment itself, but in some cases most or almost all of the fiber optic transmission connections are man-made. The amount of signal lost during fiber optic cable transmission is primarily determined by the quality and type of fiber optic cable used, with some loss of signal at each connector.


   电力电源一样,光纤电源通常也是用dB,-3dB来衡量。在铜线电路中,无论是数字信号还是模拟信号,连接器的信号丢失基本上都是“零”,也就是说,与整体线缆产生的信号丢失量相比,由于连接器接触电阻造成的欧姆丢失通常都可以忽略不计。而在大多数的光纤安装系统中,情况则截然相反。在AV应用中,小于1000英尺的光纤线缆信号丢失基本都会小于3dB。在几公里远距离传输情形下,多模光纤色散就变得非常重要,因此,最好采用低信号丢失的单模光纤。但无论是近距离传输还是远距离传输,接触传输信号的每个连接器接口都会产生大量的信号丢失,通常,最大部分的信号丢失都发生在输出端,安装一套好的光纤连接器的关键就是尽量将互相连接的光纤之间的接口信号丢失最小化,保持信号丢失在一定的估算范围之内,为系统的长期运行提供稳定性。连接器接口的信号丢失也是用dB衡量。因为光纤末端连接不恰当,光路的中断会导致一定量的信号丢失,如光纤表面差、非平行端连接等情况也会让信号丢失率远远大于预期信号丢失量。

The same as the power supply, fiber optic power supply is usually measured in dB, -3dB. In a copper circuit, whether digital or analog signals, the connector loss of signal is basically "zero", that is, compared with the amount of signal loss caused by the overall cable, due to the connector contact resistance Ohm losses are usually negligible. In most fiber-optic installations, the situation is the opposite. In AV applications, less than 1000 feet of fiber optic cable signal loss will be basically less than 3dB. Multimode fiber dispersion becomes very important for several kilometers of transmission, so it is best to use single-mode fiber with low signal loss. However, no matter whether it is a short-range transmission or a long-distance transmission, a large amount of signal loss occurs on each connector interface that contacts the transmission signal. Usually, the largest part of the signal loss occurs at the output. The key to installing a good optical fiber connector It is to minimize the signal loss between the interconnected optical fibers and to keep the signal loss within a certain range of estimation for the long-term stability of the system. Signal loss at the connector interface is also measured in dB. Because fiber ends are not properly connected, the interruption of the optical path can result in loss of a certain amount of signal, such as poor optical fiber surfaces and non-parallel end connections, which can result in far less signal loss than expected signal loss.
