As a synonym for high-speed and effective network, optical fiber networks are widely used in communication systems. Achieving transparent and high-survivability all-optical communication networks is the development goal of broadband communication networks. As an important basic technology in all-optical communication networks, the development and application of

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wir

Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of

The metropolitan area Optical cable line is mainly the pipeline optical cable, supplemented by the aerial and other laying way very few optical cables, its characteristics are: The line section is relatively short, can be divided into local trunking, user access network backbone and user to introduce optical cable,

Remember to enable the software drive and enable it again in CMOS to speed up the startup. The software drive is available, but not the optical drive. I saw the CD drive detected on the motherboard in CMOS. I think it must be a system problem. I checked the information on the Internet and found that, it is likely that the driver in the ide ata/atapi controller in the Device Manager has a problem. Program The device type in is changed to none. It turn

The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed. The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indi

Optical fiber category (1) There are many types of optical fibers and various classification methods. From the material point of view According to the materials used for optical fiber manufacturing, there are Z optical fiber, multi-component glass optical fiber, plastic pa

Principle and sensing process of Distributed Optical Fiber Temperature Measuring System The Distributed Optical Fiber Temperature measuring system can be divided into three types based on the backward scattering principle: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering D

Virtual optical drive is a kind of simulated optical drive (CD-ROM) tool software, you can generate and your computer installed on the optical drive function identical virtual optical drive, General optical drive can do the same thing virtual

Before giving you a detailed introduction to the optical fiber access technology, let us first understand the features of China's FTTH target market, and then fully introduce the importance of the FTTH technology risks, avoid blindly requiring full-service access. The existing FTTH technology mainly includes Passive Optical Network-PON (Passive Optical Network) A
